• JUnit - Testing a method that in turn invokes a few more methods

  - by stratwine

  Hi, This is my doubt on what we regard as a "unit" while unit-testing. say I have a method like this, public String myBigMethod() { String resultOne = moduleOneObject.someOperation(); String resultTwo = moduleTwoObject.someOtherOperation(resultOne); return resultTwo; } ( I have unit-tests written for someOperation() and someOtherOperation() seperately ) and this myBigMethod() kinda integrates ModuleOne and ModuleTwo by using them as above, then, is the method "myBigMethod()" still considered as a "unit" ? Should I be writing a test for this "myBigMethod()" ? Say I have written a test for myBigMethod()... If testSomeOperation() fails, it would also result in testMyBigMethod() to fail... Now testMyBigMethod()'s failure might show a not-so-correct-location of the bug. One-Cause causing two tests to fail doesn't look so good to me. But donno if there's any better way...? Is there ? Thanks !

• unit testing methods with arrays as argument

  - by Ryan

  I am porting over some C++ assembly to VB that performs demodulation of various waveforms. I decided to go the unit test route instead of building a test app to get a feel for how testing is performed. The original demodulation code accepts an array that is the waveform along with some other arguments. How should one go about performing a test on something that has an array as an argument? Is it acceptable to generate fake data in a file and read it in at the beginning of the test? On a side note - The original C++ code was written because we were performing math that we couldn't do in VB6 so we had to cross boundaries between C++ and VB6 and arrays were used. Is there a "better" way of handling large amounts of data in the .NET world that us VB6 programmers may not yet be privy to? Or if we aren't crossing that managed/un-managed boundary, should we be representing our data as objects instead? Thanks all!

• C# Gui setting control.Enabled to false fires OnClick event???

  - by Daniel

  For some really weird reason when i set the .Enabled property to false on a simple text box on a small GUI, it fires a radio buttons OnClick event and its causing lots of problems. I have breakpointed the txtBox.Enabled = false; and after stepping over OR into it i jump straight to the OnClick event of the radio button control Here is the call stack as that happened: TestGUI.exe!TestGUI.frmMain.radiobuttonClicked(object sender = {Text = "Download Single Episode" Checked = true}, System.EventArgs e = {System.EventArgs}) Line 67 C# System.Windows.Forms.dll!System.Windows.Forms.Control.OnClick(System.EventArgs e) + 0x70 bytes System.Windows.Forms.dll!System.Windows.Forms.RadioButton.OnClick(System.EventArgs e) + 0x27 bytes System.Windows.Forms.dll!System.Windows.Forms.RadioButton.OnEnter(System.EventArgs e = {System.EventArgs}) + 0x3e bytes System.Windows.Forms.dll!System.Windows.Forms.Control.NotifyEnter() + 0x20 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.UpdateFocusedControl() + 0x195 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.AssignActiveControlInternal(System.Windows.Forms.Control value = {Text = "Download Single Episode" Checked = true}) + 0x54 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.ActivateControlInternal(System.Windows.Forms.Control control, bool originator = false) + 0x76 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.SetActiveControlInternal(System.Windows.Forms.Control value = {Text = "Download Single Episode" Checked = true}) + 0x73 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.SetActiveControl(System.Windows.Forms.Control ctl) + 0x33 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.ActiveControl.set(System.Windows.Forms.Control value) + 0x5 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.Select(bool directed, bool forward) + 0x1b bytes System.Windows.Forms.dll!System.Windows.Forms.Control.SelectNextControl(System.Windows.Forms.Control ctl, bool forward, bool tabStopOnly, bool nested, bool wrap) + 0x7b bytes System.Windows.Forms.dll!System.Windows.Forms.Control.SelectNextControlInternal(System.Windows.Forms.Control ctl, bool forward, bool tabStopOnly, bool nested, bool wrap) + 0x4a bytes System.Windows.Forms.dll!System.Windows.Forms.Control.SelectNextIfFocused() + 0x61 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.Enabled.set(bool value) + 0x42 bytes What the hell?

• ASP.NET Unit Testing - WatiN and Windows 7 / Internet Explorer 8

  - by tyndall

  Any tricks in getting WatiN to run on Win7/IE8? My code: browser = new IE(); browser.GoTo("http://testserver"); browser.TextField(Find.ByName("txtUser")).TypeText("tyndall"); The third line never really runs and I get an error back: System.Runtime.InteropServices.COMException : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) The second line seems to run. IE8 appears and is navigated to the correct URL.

• Testing bash scripts

  - by nimcap

  We have a system that has some bash scripts running besides Java code. Since we are trying to "Test Everything That Could Possibly Break" and those bash scripts may break, we want to test them. The problem is it is hard to test the scripts. Is there a way or a best practice to test bash scripts? Or should we quit using bash scripts and look for alternative solutions that are testable?

I wont something I can just drop an 'agent' on the servers, and then do all the config and monitoring and notifications on a nice slick 3rd party system. So essential Zabbix Meats New Relic meets Pingdom. Any ideas?

• Bit by bit comparison of using Java or Python for unit testing frameworks and Selenium

  - by Anirudh

  Currently we are in the process of finalizing which language out of Java, Python should be used for Automation using selenium webdriver and a suitable unit testing frameworks. I have made use of Junit, TestNG and webdriver while using with Java and have designed frameworks without much fuss before. I am new to python though I came across pyhton's unit testing frameworks like unittest, pyunit, nose e.t.c but I have doubts if they would be as successful as testNG or Java. I would like to analyze point by point when used with selenium webdriver as below: 1)I have read that as Python is an interpreted language hence it's execution is slower, so say if I have to run 1000 test cases which take about 6 hours to run in Java, would python take considerably longer time for the same test cases like 8 hours? 2)Can the Python unit testing framework be as flexible as a Java unit testing framework like testNG in terms or Grouping the tests, parallel execution, skipping test. e.t.c 3)Also one point that I think of is that Python with selenium webdriver doeasn't have as big or learned community as we have for Java with webdriver, say if I run into trouble with something I am more likely to find an answer for Java as compared to python? 4)Somewhat related to point 3, is it safe to rely on tools, plugins or even webderiver's python's binding as a continuously well maintained? 5)One major drawback as I see while using python's unit testing framework is lack of boilerplate code or libraries for nicely illustrative HTML reports preferably historical reports with Pie charts, bar graphs and timelines as we have in case of Java like Allure, TestNG's default reports, reportNG or Junit reports with the help of ANT as shown below Allure Reports Junit Historical reports Also I would like to emphasize on the fact if there is a way for one to write the framework in java and make libraries or utilities according to out application in webdriver which can easily be called or integrated in with python code or modules? That would actually solve the problem for us as the client would be able to use the code we write in Java and make use of the same or call it from their python modules?

• What is the best way to go about testing that we handle failures appropriately?

  - by Earlz

  we're working on error handling in an application. We try to have fairly good automated test coverage. One big problem though is that we don't really know of a way to test some of our error handling. For instance, we need to test that whenever there is an uncaught exception, a message is sent to our server with exception information. The big problem with this is that we strive to never have an uncaught exception(and instead have descriptive error messages). So, how do we test something what we never want to actually happen?

• use networkmanager without system tray

  - by Yaakov Belch

  I use the minimal "fast lightweight window manager" (fwlm) which doesn't have a system tray. I need a simple program to manage my WIFI and virtual private netwok connection --- and found the NetworkManager. The problem is that the NetworkManager is a system-tray icon: I cannot see it or click on it in my fwlm windows manager. Hence, I ask: Is there any way to start the NetworkManager directly without using the system tray?

• What type of code is suitable for unit testing?

  - by RPK

  In Test Driven Development, what type of code is testable? I am using a Micro-ORM (PetaPoco) and I have several methods that interact with the database like: AddCustomer UpdateRecord etc. I want to know how to write a test for these methods. I searched YouTube for videos on writing a test for DAL, but I didn't find any. I want to know which method or class is testable and how to write a test before writing the code itself.

• A new name for unit tests

  - by Will

  I never used to like unit testing. I always thought it increased the amount of work I had to do. Turns out, that's only true in terms of the actual number of lines of code you write and furthermore, this is completely offset by the increase in the number of lines of useful code that you can write in an hour with tests and test driven development. Now I love unit tests as they allow me to write useful code, that quite often works first time! (knock on wood) I have found that people are reluctant to do unit tests or start a project with test driven development if they are under strict time-lines or in an environment where others don't do it, so they don't. Kinda like, a cultural refusal to even try. I think one of the most powerful things about unit testing is the confidence that it gives you to undertake refactoring. It also gives new found hope, that I can give my code to someone else to refactor/improve, and if my unit tests still work, I can use the new version of the library that they modified, pretty much, without fear. It's this last aspect of unit testing that I think needs a new name. The unit test is more like a contract of what this code should do now, and in the future. When I hear the word testing, I think of mice in cages, with multiple experiments done on them to see the effectiveness of a compound. This is not what unit testing is, we're not trying out different code to see what is the most affective approach, we're defining what outputs we expect with what inputs. In the mice example, unit tests are more like the definitions of how the universe will work as opposed to the experiments done on the mice. Am I on crack or does anyone else see this refusal to do testing and do they think it's a similar reason they don't want to do it? What reasons do you / others give for not testing? What do you think their motivations are in not unit testing? And as a new name for unit testing that might get over some of the objections, how about jContract? (A bit Java centric I know :), or Unit Contracts?

• System beeps continuously if both RAM sticks inserted

  - by JGB146

  I have two sticks of OCZ 2GB PC2 9600 RAM. When I attempt to boot with both sticks inserted, I am met with a continuous string of system beeps (and no bootup). The system boots fine when only one stick is inserted, but obviously that leaves me with less RAM than I'd like to have. What could the problem be? System specs are: Gigabyte GA-EP45-UD3L Intel Core 2 Quad Q9400 Sticks of OCZ 2GB PC2 9600 RAM Zotac GeForce GTS 250 1GB 2x Seagate 500GB SATA HDs

• Shared block device file system (cluster file system without networking)

  - by fungs

  Is there any file system that can be mounted multiple times and supports concurrent file access for Linux? Basically I want something like a cluster file system but without the need to have a running network for a distributed lock manager. That can be very handy in connection with virtual machines that can share data with the host or another VM without the need to create a network link. This I want to avoid to keep the network architecture secure (virtual machine in DMZ) but share large files. No need to scale it up, just two machines that mount the same block device. Shouldn't it be possible to have file locking information right on the disk?

• Access denied on file system for System Administrator

  - by NLV

  Hello Yesterday I got win32.Saltiy virus and did some damage before my Kaspersky suite caught it. Now I've cleaned all the viruses using Kaspersky but I believe the changes it did to the registry/policies are still there. I'm not able to have write access on the entire file system. It is showing up the access denied the error. I'm in the local system administrators group. I've tried removing and re-adding it (with a reboot). But still no luck. Any ideas on how can I fix this?

• Will multivariate (A/B) testing applied with 302 redirects to a subdomain affect my Google ranking?

  - by Lior

  I want to do an A B test of an entire site for a new design and UX with only slight changes in content (a big brand site that has good Google rankings for many generic keywords. My idea of implementation is doing a 302 redirect to the new version (placing it on www1 subdomain) and allowing only user agents of known browsers to pass. The test version will have disallow all in the robots text. Will Google treat this favorably or do I have to use Google Website Optimizer (which will give me tracking headaches)?

• What we have to measure for measuring server performance If we can't measure the server processing time from client side?

  - by AsadYarKhan

  If we can not measure the server processing time from client side then which attributes will be good to measure in client side for measuring server side performance and What attributes are important ? I know we can get the server response time, latency and Throughput etc,but how do we understand/interpret the result of server side from these attrubutes. How can we analyse that whether my code is taking lots of time,whether Web Server, whether it is because of Server Machine(H/W).how would i know that which thing needs to be upgrade or improve.Please tell me any article or any book something that I need to study or explain here If you can so I can interpret the result of server side using these attributes response time, latency and throughput.You can tell other performance attribute if I need to understand the server result.

• System reserved

  - by arun sidharth

  I have a HP laptop. I upgraded to windows 7 ultimate from home basic. Now I'm trying to upgrade to Windows 8 but when I do I get a message saying not enough system partition. So I opened the disk manager and increased the size of system reserved partition and it was of no use I still got the same error. Then I unfortunately deleted the 100MB system reserved partition by right clicking it and clicking format in the disk manager! Now I am not able to boot any CD's from the startup including OS and recovery CD. Whenever I press esc it always goes to the login screen and it doesn't say anything about the boot from CD option. Now I could not even use my recovery CD. I have 3 questions: Is it necesseary to create a system reserved partition if so how to create it? How to use my recovery cd How to install win 8
