  • Is it OK to repeat code for unit tests?

    - by Pete
    I wrote some sorting algorithms for a class assignment and I also wrote a few tests to make sure the algorithms were implemented correctly. My tests are only like 10 lines long and there are 3 of them but only 1 line changes between the 3 so there is a lot of repeated code. Is it better to refactor this code into another method that is then called from each test? Wouldn't I then need to write another test to test the refactoring? Some of the variables can even be moved up to the class level. Should testing classes and methods follow the same rules as regular classes/methods? Here's an example: [TestMethod] public void MergeSortAssertArrayIsSorted() { int[] a = new int[1000]; Random rand = new Random(DateTime.Now.Millisecond); for(int i = 0; i < a.Length; i++) { a[i] = rand.Next(Int16.MaxValue); } int[] b = new int[1000]; a.CopyTo(b, 0); List<int> temp = b.ToList(); temp.Sort(); b = temp.ToArray(); MergeSort merge = new MergeSort(); merge.mergeSort(a, 0, a.Length - 1); CollectionAssert.AreEqual(a, b); } [TestMethod] public void InsertionSortAssertArrayIsSorted() { int[] a = new int[1000]; Random rand = new Random(DateTime.Now.Millisecond); for (int i = 0; i < a.Length; i++) { a[i] = rand.Next(Int16.MaxValue); } int[] b = new int[1000]; a.CopyTo(b, 0); List<int> temp = b.ToList(); temp.Sort(); b = temp.ToArray(); InsertionSort merge = new InsertionSort(); merge.insertionSort(a); CollectionAssert.AreEqual(a, b); }

  • Part 3 of 4 : Tips/Tricks for Silverlight Developers.

    - by mbcrump
    Part 1 | Part 2 | Part 3 | Part 4 I wanted to create a series of blog post that gets right to the point and is aimed specifically at Silverlight Developers. The most important things I want this series to answer is : What is it?  Why do I care? How do I do it? I hope that you enjoy this series. Let’s get started: Tip/Trick #11) What is it? Underline Text in a TextBlock. Why do I care? I’ve seen people do some crazy things to get underlined text in a Silverlight Application. In case you didn’t know there is a property for that. How do I do it: On a TextBlock you have a property called TextDecorations. You can easily set this property in XAML or CodeBehind with the following snippet: <UserControl x:Class="SilverlightApplication19.MainPage" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <TextBlock Name="txtTB" Text="MichaelCrump.NET" TextDecorations="Underline" /> </Grid> </UserControl> or you can do it in CodeBehind… txtTB.TextDecorations = TextDecorations.Underline;   Tip/Trick #12) What is it? Get the browser information from a Silverlight Application. Why do I care? This will allow you to program around certain browser conditions that otherwise may not be aware of. How do I do it: It is very easy to extract Browser Information out a Silverlight Application by using the BrowserInformation class. You can copy/paste this code snippet to have access to all of them. string strBrowserName = HtmlPage.BrowserInformation.Name; string strBrowserMinorVersion = HtmlPage.BrowserInformation.BrowserVersion.Minor.ToString(); string strIsCookiesEnabled = HtmlPage.BrowserInformation.CookiesEnabled.ToString(); string strPlatform = HtmlPage.BrowserInformation.Platform; string strProductName = HtmlPage.BrowserInformation.ProductName; string strProductVersion = HtmlPage.BrowserInformation.ProductVersion; string strUserAgent = HtmlPage.BrowserInformation.UserAgent; string strBrowserVersion = HtmlPage.BrowserInformation.BrowserVersion.ToString(); string strBrowserMajorVersion = HtmlPage.BrowserInformation.BrowserVersion.Major.ToString(); Tip/Trick #13) What is it? Always check the minRuntimeVersion after creating a new Silverlight Application. Why do I care? Whenever you create a new Silverlight Application and host it inside of an ASP.net website you will notice Visual Studio generates some code for you as shown below. The minRuntimeVersion value is set by the SDK installed on your system. Be careful, if you are playing with beta’s like “Lightswitch” because you will have a higher version of the SDK installed. So when you create a new Silverlight 4 project and deploy it your customers they will get a prompt telling them they need to upgrade Silverlight. They also will not be able to upgrade to your version because its not released to the public yet. How do I do it: Open up the .aspx or .html file Visual Studio generated and look for the line below. Make sure it matches whatever version you are actually targeting. Tip/Trick #14) What is it? The VisualTreeHelper class provides useful methods for involving nodes in a visual tree. Why do I care? It’s nice to have the ability to “walk” a visual tree or to get the rendered elements of a ListBox. I have it very useful for debugging my Silverlight application. How do I do it: Many examples exist on the web, but say that you have a huge Silverlight application and want to find the parent object of a control.  In the code snippet below, we would get 3 MessageBoxes with (StackPanel first, Grid second and UserControl Third). This is a tiny application, but imagine how helpful this would be on a large project. <UserControl x:Class="SilverlightApplication18.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <StackPanel> <Button Content="Button" Height="23" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> </StackPanel> </Grid> </UserControl> private void button1_Click(object sender, RoutedEventArgs e) { DependencyObject obj = button1; while ((obj = VisualTreeHelper.GetParent(obj)) != null) { MessageBox.Show(obj.GetType().ToString()); } } Tip/Trick #15) What is it? Add ChildWindows to your Silverlight Application. Why do I care? ChildWindows are a great way to direct a user attention to a particular part of your application. This could be used when saving or entering data. How do I do it: Right click your Silverlight Application and click Add then New Item. Select Silverlight Child Window as shown below. Add an event and call the ChildWindow with the following snippet below: private void button1_Click(object sender, RoutedEventArgs e) { ChildWindow1 cw = new ChildWindow1(); cw.Show(); } Your main application can still process information but this screen forces the user to select an action before proceeding. The code behind of the ChildWindow will look like the following: namespace SilverlightApplication18 { public partial class ChildWindow1 : ChildWindow { public ChildWindow1() { InitializeComponent(); } private void OKButton_Click(object sender, RoutedEventArgs e) { this.DialogResult = true; //TODO: Add logic to save what the user entered. } private void CancelButton_Click(object sender, RoutedEventArgs e) { this.DialogResult = false; } } } Thanks for reading and please come back for Part 4.  Subscribe to my feed CodeProject

  • Enum types, FlagsAttribute & Zero value – Part 2

    - by nmgomes
    In my previous post I wrote about why you should pay attention when using enum value Zero. After reading that post you are probably thinking like Benjamin Roux: Why don’t you start the enum values at 0x1? Well I could, but doing that I lose the ability to have Sync and Async mutually exclusive by design. Take a look at the following enum types: [Flags] public enum OperationMode1 { Async = 0x1, Sync = 0x2, Parent = 0x4 } [Flags] public enum OperationMode2 { Async = 0x0, Sync = 0x1, Parent = 0x2 } To achieve mutually exclusion between Sync and Async values using OperationMode1 you would have to operate both values: protected void CheckMainOperarionMode(OperationMode1 mode) { switch (mode) { case (OperationMode1.Async | OperationMode1.Sync | OperationMode1.Parent): case (OperationMode1.Async | OperationMode1.Sync): throw new InvalidOperationException("Cannot be Sync and Async simultaneous"); break; case (OperationMode1.Async | OperationMode1.Parent): case (OperationMode1.Async): break; case (OperationMode1.Sync | OperationMode1.Parent): case (OperationMode1.Sync): break; default: throw new InvalidOperationException("No default mode specified"); } } but this is a by design constraint in OperationMode2. Why? Simply because 0x0 is the neutral element for the bitwise OR operation. Knowing this singularity, replacing and simplifying the previous method, you get: protected void CheckMainOperarionMode(OperationMode2 mode) { switch (mode) { case (OperationMode2.Sync | OperationMode2.Parent): case (OperationMode2.Sync): break; case (OperationMode2.Parent): default: break; } This means that: if both Sync and Async values are specified Sync value always win (Zero is the neutral element for bitwise OR operation) if no Sync value specified, the Async method is used. Here is the final method implementation: protected void CheckMainOperarionMode(OperationMode2 mode) { if (mode & OperationMode2.Sync == OperationMode2.Sync) { } else { } } All content above prove that Async value (0x0) is useless from the arithmetic perspective, but, without it we lose readability. The following IF statements are logically equals but the first is definitely more readable: if (OperationMode2.Async | OperationMode2.Parent) { } if (OperationMode2.Parent) { } Here’s another example where you can see the benefits of 0x0 value, the default value can be used explicitly. <my:Control runat="server" Mode="Async,Parent"> <my:Control runat="server" Mode="Parent">

  • What's new in EJB 3.2 ? - Java EE 7 chugging along!

    - by arungupta
    EJB 3.1 added a whole ton of features for simplicity and ease-of-use such as @Singleton, @Asynchronous, @Schedule, Portable JNDI name, EJBContainer.createEJBContainer, EJB 3.1 Lite, and many others. As part of Java EE 7, EJB 3.2 (JSR 345) is making progress and this blog will provide highlights from the work done so far. This release has been particularly kept small but include several minor improvements and tweaks for usability. More features in EJB.Lite Asynchronous session bean Non-persistent EJB Timer service This also means these features can be used in embeddable EJB container and there by improving testability of your application. Pruning - The following features were made Proposed Optional in Java EE 6 and are now made optional. EJB 2.1 and earlier Entity Bean Component Contract for CMP and BMP Client View of an EJB 2.1 and earlier Entity Bean EJB QL: Query Language for CMP Query Methods JAX-RPC-based Web Service Endpoints and Client View The optional features are moved to a separate document and as a result EJB specification is now split into Core and Optional documents. This allows the specification to be more readable and better organized. Updates and Improvements Transactional lifecycle callbacks in Stateful Session Beans, only for CMT. In EJB 3.1, the transaction context for lifecyle callback methods (@PostConstruct, @PreDestroy, @PostActivate, @PrePassivate) are defined as shown. @PostConstruct @PreDestroy @PrePassivate @PostActivate Stateless Unspecified Unspecified N/A N/A Stateful Unspecified Unspecified Unspecified Unspecified Singleton Bean's transaction management type Bean's transaction management type N/A N/A In EJB 3.2, stateful session bean lifecycle callback methods can opt-in to be transactional. These methods are then executed in a transaction context as shown. @PostConstruct @PreDestroy @PrePassivate @PostActivate Stateless Unspecified Unspecified N/A N/A Stateful Bean's transaction management type Bean's transaction management type Bean's transaction management type Bean's transaction management type Singleton Bean's transaction management type Bean's transaction management type N/A N/A For example, the following stateful session bean require a new transaction to be started for @PostConstruct and @PreDestroy lifecycle callback methods. @Statefulpublic class HelloBean {   @PersistenceContext(type=PersistenceContextType.EXTENDED)   private EntityManager em;    @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)   @PostConstruct   public void init() {        myEntity = em.find(...);   }   @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)    @PostConstruct    public void destroy() {        em.flush();    }} Notice, by default the lifecycle callback methods are not transactional for backwards compatibility. They need to be explicitly opt-in to be made transactional. Opt-out of passivation for stateful session bean - If your stateful session bean needs to stick around or it has non-serializable field then the bean can be opt-out of passivation as shown. @Stateful(passivationCapable=false)public class HelloBean {    private NonSerializableType ref = ... . . .} Simplified the rules to define all local/remote views of the bean. For example, if the bean is defined as: @Statelesspublic class Bean implements Foo, Bar {    . . .} where Foo and Bar have no annotations of their own, then Foo and Bar are exposed as local views of the bean. The bean may be explicitly marked @Local as @Local@Statelesspublic class Bean implements Foo, Bar {    . . .} then this is the same behavior as explained above, i.e. Foo and Bar are local views. If the bean is marked @Remote as: @Remote@Statelesspublic class Bean implements Foo, Bar {    . . .} then Foo and Bar are remote views. If an interface is marked @Local or @Remote then each interface need to be explicitly marked explicitly to be exposed as a view. For example: @Remotepublic interface Foo { . . . }@Statelesspublic class Bean implements Foo, Bar {    . . .} only exposes one remote interface Foo. Section 4.9.7 from the specification provide more details about this feature. TimerService.getAllTimers is a newly added convenience API that returns all timers in the same bean. This is only for displaying the list of timers as the timer can only be canceled by its owner. Removed restriction to obtain the current class loader, and allow to use java.io package. This is handy if you want to do file access within your beans. JMS 2.0 alignment - A standard list of activation-config properties is now defined destinationLookup connectionFactoryLookup clientId subscriptionName shareSubscriptions Tons of other clarifications through out the spec. Appendix A provide a comprehensive list of changes since EJB 3.1. ThreadContext in Singleton is guaranteed to be thread-safe. Embeddable container implement Autocloseable. A complete replay of Enterprise JavaBeans Today and Tomorrow from JavaOne 2012 can be seen here (click on CON4654_mp4_4654_001 in Media). The specification is still evolving so the actual property or method names or their actual behavior may be different from the currently proposed ones. Are there any improvements that you'd like to see in EJB 3.2 ? The EJB 3.2 Expert Group would love to hear your feedback. An Early Draft of the specification is available. The latest version of the specification can always be downloaded from here. Java EE 7 Specification Status EJB Specification Project JIRA of EJB Specification JSR Expert Group Discussion Archive These features will start showing up in GlassFish 4 Promoted Builds soon.

  • Do you know your DNS server?

    - by John Paul Cook
    If you don’t know your DNS server is valid, you need to find out before July 9. The FBI found rogue DNS servers and replaced them with clean, safe DNS servers to protect the public. These safe, clean servers will be turned off on July 9, 2012. If your computer was compromised to use the rogue servers, it will stop resolving DNS queries on July 9 when the clean servers are turned off. The FBI has provided full technical details at http://www.fbi.gov/news/stories/2011/november/malware_110911/DNS-changer-malware.pdf...(read more)

  • How do you make a bullet ricochet off a vertical wall?

    - by Bagofsheep
    First things first. I am using C# with XNA. My game is top-down and the player can shoot bullets. I've managed to get the bullets to ricochet correctly off horizontal walls. Yet, despite using similar methods (e.g. http://stackoverflow.com/questions/3203952/mirroring-an-angle) and reading other answered questions about this subject I have not been able to get the bullets to ricochet off a vertical wall correctly. Any method I've tried has failed and sometimes made ricocheting off a horizontal wall buggy. Here is the collision code that calls the ricochet method: //Loop through returned tile rectangles from quad tree to test for wall collision. If a collision occurs perform collision logic. for (int r = 0; r < returnObjects.Count; r++) if (Bullets[i].BoundingRectangle.Intersects(returnObjects[r])) Bullets[i].doCollision(returnObjects[r]); Now here is the code for the doCollision method. public void doCollision(Rectangle surface) { if (Ricochet) doRicochet(surface); else Trash = true; } Finally, here is the code for the doRicochet method. public void doRicochet(Rectangle surface) { if (Position.X > surface.Left && Position.X < surface.Right) { //Mirror the bullet's angle. Rotation = -1 * Rotation; //Moves the bullet in the direction of its rotation by given amount. moveFaceDirection(Sprite.Width * BulletScale.X); } else if (Position.Y > surface.Top && Position.Y < surface.Bottom) { } } Since I am only dealing with vertical and horizontal walls at the moment, the if statements simply determine if the object is colliding from the right or left, or from the top or bottom. If the object's X position is within the boundaries of the tile's X boundaries (left and right sides), it must be colliding from the top, and vice verse. As you can see, the else if statement is empty and is where the correct code needs to go.

  • Runtime error on UVa Online Judge on Erdos Number

    I am solving the Erdos number problem from the programming challenges in JAVA. The code runs perfectly in my machine. However on the online judge it results in a runtime error.

  • What are different ways to reduce latency between a server and a web application? [closed]

    - by jjoensuu
    this is a question about a web application that provides SOAP web services. For the sake of this question, this web app is hosted on a server SERVER B which is located in California. We have an automated, scheduled, process running on a server SERVER A, located in New York. This scheduled process is supposed to send SOAP messages to SERVER B every so often, but this process typically dies soon after starting. We have now been told by the vendor that reason why the process dies is because of the latency between SERVER A and SERVER B. The data traffic is routed through many diffent public networks. There is no dedicated line between SERVER A and SERVER B. As a result I have been asked to look into ways to reduce the latency between SERVER A and SERVER B. So I wanted to ask, what are the different ways to reduce latency in a situation like this? For example, would it help to switch from HTTPS to some other secure protocol? (the thought here is that perhaps some other alternative would require fewer handshakes than HTTPS). Or would a VPN help? If a VPN would reduce the latency, how would it do that? NOTE: I am not looking for an explicit answer that would work in my specific situation. I am more like looking just for a simple list of what technologies could be used for this. I will still have to evaluate the technologies and discuss them internally with others, so the list would just be a starting point. Here I am assuming that there exists very few ways to reduce latency between two servers that communicate across public networks using HTTPS. Feel free to correct me if this assumption is wrong and please ask if there is a need for specific information. NOTE 2: A list of technologies is a specific answer to the question I stated in the title. NOTE 3: Its rather dumb to close this question when it is after all about me looking for information and furthermore this information can clearly be useful for others. Anyway luckily there are other sites where I can ask around. StackExchange seems to attached to their own philosophical principles. Many thanks

  • Olympic clock stops after a few hours: can this even be a software problem? [closed]

    - by mvexel
    I fail to understand how something uncomplicated as a countdown clock can fail - to much public humiliation of sponsor and renowned clock maker Omega - after only a few hours of operation. The clock, which was 'developed by our experts and fully tested' according to a spokesperson who goes on to say that is 'not immediately apparent what has caused the problem'. Can this even be a software problem? What has gone wrong here?

  • Key Promoter for NetBeans

    - by Geertjan
    Whenever a menu item or toolbar button is clicked, it would be handy if NetBeans were to tell you 'hey, did you know, you can actually do this via the following keyboard shortcut', if a keyboard shortcut exists for the invoked action. After all, ultimately, a lot of developers would like to do everything with the keyboard and a key promoter feature of this kind is a helpful tool in learning the keyboard shortcuts related to the menu items and toolbar buttons you're clicking with your mouse. Above, you see the balloon message that appears for each menu item and toolbar button that you click and, below, you can see a list of all the actions that have been logged in the Notifications window. That happens automatically when an action is invoked (assuming the plugin described in this blog entry is installed), showing the display name of the action, together with the keyboard shortcut, which is presented as a hyperlink which, when clicked, re-invokes the action (which might not always be relevant, especially for context-sensitive actions, though for others it is quite useful, e.g., reopen the New Project wizard). And here's all the code. Notice that I'm hooking into the 'uigestures' functionality, which was suggested by Tim Boudreau, and I have added my own handler, which was suggested by Jaroslav Tulach, which gets a specific parameter from each new log entry handled by the 'org.netbeans.ui.actions' logger, makes sure that the parameter actually is an action, and then gets the relevant info from the action, if the relevant info exists: @OnShowingpublic class Startable implements Runnable {    @Override    public void run() {        Logger logger = Logger.getLogger("org.netbeans.ui.actions");        logger.addHandler(new StreamHandler() {            @Override            public void publish(LogRecord record) {                Object[] parameters = record.getParameters();                if (parameters[2] instanceof Action) {                    Action a = (Action) parameters[2];                    JMenuItem menu = new JMenuItem();                    Mnemonics.setLocalizedText(                            menu,                             a.getValue(Action.NAME).toString());                    String name = menu.getText();                    if (a.getValue(Action.ACCELERATOR_KEY) != null) {                        String accelerator = a.getValue(Action.ACCELERATOR_KEY).toString();                        NotificationDisplayer.getDefault().notify(                                name,                                 new ImageIcon("/org/nb/kp/car.png"),                                 accelerator,                                 new ActionListener() {                            @Override                            public void actionPerformed(ActionEvent e) {                                a.actionPerformed(e);                            }                        });                    }                }            }        });    }} Indeed, inspired by the Key Promoter in IntelliJ IDEA. Interested in trying it out? If there's interest in it, I'll put it in the NetBeans Plugin Portal.

  • StringBuffer behavior in LWJGL

    - by Michael Oberlin
    Okay, I've been programming in Java for about ten years, but am entirely new to LWJGL. I have a specific problem whilst attempting to create a text console. I have built a class meant to abstract input polling to it, which (in theory) captures key presses from the Keyboard object and appends them to a StringBuilder/StringBuffer, then retrieves the completed string after receiving the ENTER key. The problem is, after I trigger the String return (currently with ESCAPE), and attempt to print it to System.out, I consistently get a blank line. I can get an appropriate string length, and I can even sample a single character out of it and get complete accuracy, but it never prints the actual string. I could swear that LWJGL slipped some kind of thread-safety trick in while I wasn't looking. Here's my code: static volatile StringBuffer command = new StringBuffer(); @Override public void chain(InputPoller poller) { this.chain = poller; } @Override public synchronized void poll() { //basic testing for modifier keys, to be used later on boolean shift = false, alt = false, control = false, superkey = false; if(Keyboard.isKeyDown(Keyboard.KEY_LSHIFT) || Keyboard.isKeyDown(Keyboard.KEY_RSHIFT)) shift = true; if(Keyboard.isKeyDown(Keyboard.KEY_LMENU) || Keyboard.isKeyDown(Keyboard.KEY_RMENU)) alt = true; if(Keyboard.isKeyDown(Keyboard.KEY_LCONTROL) || Keyboard.isKeyDown(Keyboard.KEY_RCONTROL)) control = true; if(Keyboard.isKeyDown(Keyboard.KEY_LMETA) || Keyboard.isKeyDown(Keyboard.KEY_RMETA)) superkey = true; while(Keyboard.next()) if(Keyboard.getEventKeyState()) { command.append(Keyboard.getEventCharacter()); } if (Framework.isConsoleEnabled() && Keyboard.isKeyDown(Keyboard.KEY_ESCAPE)) { System.out.println("Escape down"); System.out.println(command.length() + " characters polled"); //works System.out.println(command.toString().length()); //works System.out.println(command.toString().charAt(4)); //works System.out.println(command.toString().toCharArray()); //blank line! System.out.println(command.toString()); //blank line! Framework.disableConsole(); } //TODO: Add command construction and console management after that } } Maybe the answer's obvious and I'm just feeling tired, but I need to walk away from this for a while. If anyone sees the issue, please let me know. This machine is running the latest release of Java 7 on Ubuntu 12.04, Mate desktop environment. Many thanks.

  • What is the most appropriate testing method in this scenario?

    - by Daniel Bruce
    I'm writing some Objective-C apps (for OS X/iOS) and I'm currently implementing a service to be shared across them. The service is intended to be fairly self-contained. For the current functionality I'm envisioning there will be only one method that clients will call to do a fairly complicated series of steps both using private methods on the class, and passing data through a bunch of "data mangling classes" to arrive at an end result. The gist of the code is to fetch a log of changes, stored in a service-internal data store, that has occurred since a particular time, simplify the log to only include the last applicable change for each object, attach the serialized values for the affected objects and return this all to the client. My question then is, how do I unit-test this entry point method? Obviously, each class would have thorough unit tests to ensure that their functionality works as expected, but the entry point seems harder to "disconnect" from the rest of the world. I would rather not send in each of these internal classes IoC-style, because they're small and are only made classes to satisfy the single-responsibility principle. I see a couple possibilities: Create a "private" interface header for the tests with methods that call the internal classes and test each of these methods separately. Then, to test the entry point, make a partial mock of the service class with these private methods mocked out and just test that the methods are called with the right arguments. Write a series of fatter tests for the entry point without mocking out anything, testing the entire functionality in one go. This looks, to me, more like "integration testing" and seems brittle, but it does satisfy the "only test via the public interface" principle. Write a factory that returns these internal services and take that in the initializer, then write a factory that returns mocked versions of them to use in tests. This has the downside of making the construction of the service annoying, and leaks internal details to the client. Write a "private" initializer that take these services as extra parameters, use that to provide mocked services, and have the public initializer back-end to this one. This would ensure that the client code still sees the easy/pretty initializer and no internals are leaked. I'm sure there's more ways to solve this problem that I haven't thought of yet, but my question is: what's the most appropriate approach according to unit testing best practices? Especially considering I would prefer to write this test-first, meaning I should preferably only create these services as the code indicates a need for them.

  • How does juju expose work?

    - by user84471
    If I expose my service, for instance teamspeak server, on what address it will be running? On my server address? For example: my server has an address of 158.37.15.167. If I deploy teamspeak from my local network (10.0.0.0) connected to the server, how will it be seen in the 158.37.15.167 network? When I run juju status I get this: public-address: nodeTWO.localdomain instead of an IP address. My juju status: http://pastebin.com/z99Bhx9G

  • Are you reporting Visual Studio 2012 issues to Microsoft correctly?

    - by Tarun Arora
    Issues you may run into while using Visual Studio need to be reported to the Microsoft Product Team via the Microsoft connect site. The Microsoft team then tries to reproduce the issue using the details provided by you. If the information you provide isn’t sufficient to reproduce the issue the team tries to contact you for specifics, this not only increases the cycle time to resolution but the lack of communication also results in issues not being resolved. So, when I report an issue one part of me tells me to include as much detail about the issue as I can clubbing screen shots, repo steps, system information, visual studio version information,… the other half tells me this is so time consuming, leave it for now and come back to fill all these details later. Reporting a bug but not including the supporting information is an invitation to excuses like …     Microsoft has absolutely changed this experience for VS 2012. The Microsoft Visual Studio Feedback tool is designed to simplify the process of providing feedback and reporting issues to Microsoft that you may encounter while using Microsoft Visual Studio 2012. Note – The Microsoft Visual Studio 2012 Feedback client currently only works for VS 2012 and not any other versions of Visual Studio. Setting up the Microsoft Visual Studio 2012 Feedback client Open Visual Studio, from the Tools menu select Extension and Updates. In the Extension and Updates window, click Online from the left pane and search using the text ‘feedback’, download and Install Microsoft Visual Studio 2012 Feedback Tool by following the instructions from the wizard. Note - Restarting Visual Studio after the install is a must! How to report a bug for Visual Studio 2012? Click on the Help menu and choose Report a Bug You should see an icon Microsoft Visual Studio 2012 Feedback Tool come up in the system tray icon area You’ll need to accept the Privacy statement. You have the option of reporting the feedback as private or public. Microsoft works with several Partners, MVP’s and Vendors who get access to early bits of Microsoft products for valuation. This is where it becomes essential to report the feedback privately. I would choose the Public option otherwise. After all if it’s out there in the public, others can discover and add to it easily. You now have the option to report a new issue or add to an existing issue. Should you choose to add to an existing issue you should have the feedback ID of the issue available. This can be obtained from the Microsoft Connect site. For now I am going to focus on reporting a new feedback privately. Filling out the feedback details You will notice that VsInfo.xml and DxDiagOutput.txt are automatically attached as you enter this screen (more on that later).  Feedback Type Choose the feedback type from (Performance, Hang, Crash, Other) Note – The record button will only be enabled once you have enabled once you have chosen the feedback type, Bug-repro recording is not available for Windows Server 2008.     Effective Title and Description Enter a title that helps us differentiate the bug when it appears in a list, so that we can group it with any related bugs, assign it to a developer more effectively, and resolve it more quickly. Example: Imagine that you are submitting a bug because you tried to install Service Pack 1 and got a message that Visual Studio is not installed even though it is. Helpful:  Installed Visual Studio version not detected during Service Pack 1 setup. Not helpful:  Service Pack 1 problem. Tip: Write the problem description first, and then distil it to create a title. Example Description: Helpful: When I run Service Pack 1 Setup, I get the message "No Visual Studio version is detected" even though I have Visual Studio 2010 Ultimate and Visual C++ 2010 Express installed on my machine. Even though I uninstalled both editions, and then first reinstalled Ultimate and then Express, I still get the message. Record: Becoming a first class citizen Often a repro report is invaluable to describe and decipher the issue. Please use this feature to send actionable feedback. The record repro feature works differently depending on the feedback type you selected. Please find below details for each recording option. You can start recording simply by selecting a feedback type, and clicking on the “Record” button. When "Performance" is the bug type: When the Microsoft Visual Studio trace recorder starts, perform the actions that show the performance problem you want to report and then click on the "Stop Recording" button as soon as you experience the performance problem. Because the tool optimizes trace collection, you can run it for as long as it takes to show the problem, up to two hours. Note that, you need to stop recording as soon as the performance issue occurs, because the tool captures only the last couple minutes of your actions to optimize the trace collection. After you stop the recording, the tool takes up to two minutes to assemble the data and attach an ETLTrace.zip file to your bug report. The data includes information about Windows events and the Visual Studio code path. Note that, running the Microsoft Visual Studio trace recorder requires elevated user privilege. When "Crash" is the bug type: When the dialog box appears, select the running Visual Studio instance for which you want to show the steps that cause a crash. When the crash occurs, click on the "Stop Record" button. After you do this, two files are attached to your bug report - an AutomaticCrashDump.zip file that contains information about the crash and a ReproSteps.zip file that shows the repro steps. Repro steps are captured by Windows Problem Steps Recorder. Note that, you can pause the recording, and resume later, or for a specific step, you can add additional comments. When "Hang" is the bug type: The process for recording the steps that cause a hang resembles the one for crashes. The difference is, you can even collect a dump file after the VS hangs; start the VSFT either from the system tray or by starting a new instance of VS, select "Hang" as feedback type and click on the "Record" button. You will be prompted which VS to collect dump about, select the VS instance that hanged. VSFT collects a dump file regarding the hang, called MiniDump.zip, and attaches to your bug report. When "Other" is the bug type: When the problem step recorder starts, perform the actions that show the issue you want to report and then choose the "Stop” button. You can pause the recording, and resume later, or for a specific step, you can add additional comments. Once you’re done, ReproSteps.zip is added to your bug report. Pre-attached files It is essential for Microsoft to know what version of the the product are you currently using and what is the current configuration of your system. Note – The total size of all attachments in a bug report cannot exceed 2 GB, and every uncompressed attachment must be smaller than 512 MB. We recommend that you assemble all of your attachments, compress them together into a .zip file, and then attach the .zip file. Taking a screenshot Associate a screen shot by clicking the Take screenshot button, choose either the entire desktop, the specific monitor (useful if you are working in a multi monitor configuration) or the specific window in question. And finally … click Submit If you need further help, more details can be found here. You can view your feedback online by using the following URL “">https://connect.microsoft.com/VisualStudio/SearchResults.aspx?SearchQuery=<feedbackId>” Happy bug logging

  • Curating projects of deceased friends

    - by Ant
    A very good friend of mine, and an avid programmer, recently passed away. He left nearly 40 projects on BitBucket. Most of them are public, but a few of them are marked as private. I've decided to take on curation duties for the projects rather than leave his work to disappear. If you have been in the same situation, what did you do? Did you open-source everything? Continue development? Delete it all? I'm very interested to hear other people's experiences. There are a few reasons why some of the projects are marked as private (private projects on BitBucket are visible only to invited users and the original creator): One of them is an iOS web app that was free in the app store. I've had to remove the app from the store as I'm shutting down his web sites as a favour to his widow. However, I've already made the app public under the GPL v3 (he was a big GPL supporter). One of them contains proprietary code. It can't be open-sourced. Others are very much work-in-progress. I don't know if he intended to make them into hosted, paid services or if he wanted to give the code away under an open-source licence when they were finished. Here's a list of the private projects: Some kind of living cell simulator that uses SBML along with Runge-Kutta and Euler algorithms to do... something. There's a fair amount of code here but I don't know what it does or how far along it is. No docs. An accountacy application; it seems to have a solid DB design behind it but there's little code on top of that. A website whose purpose is to suggest good restaurants. Built on yii. Seems to have a lot of code but I'd need to set up a WAMP stack to see how far along it is. A website intended to host memorials to people who suffered from the same problem he was. Built on Joomla. I'm not sure how much of the code is just Joomla and how much is custom; again, I'd need to get Joomla running to find out. I'd just introduced him to Mercurial and BitBucket. All of the private projects are single commits of codebases he wasn't using version control with/was previously using SVN. I don't have the SVN repositories so I can't see the commit logs.
