• How to configure Visual Studio 2010 code coverage for ASP.NET MVC unit tests

  - by DigiMortal

  I just got Visual Studio 2010 code coverage work with ASP.NET MVC application unit tests. Everything is simple after you have spent some time with forums, blogs and Google. To save your valuable time I wrote this posting to guide you through the process of making code coverage work with ASP.NET MVC application unit tests. After some fighting with Visual Studio I got everything to work as expected. I am still not very sure why users must deal with this mess, but okay – I survived it. Before you start configuring Visual Studio I expect your solution meets the following needs: there are at least one library that will be tested, there is at least on library that contains tests to be run, there are some classes and some tests for them, and, of course, you are using version of Visual Studio 2010 that supports tests (I have Visual Studio 2010 Ultimate). Now open the following screenshot to separate windows and follow the steps given below. Visual Studio 2010 Test Settings window. Click on image to see it at original size.  Double click on Local.testsettings under Solution Items. Test settings window will be opened. Select “Data and Diagnostics” from left pane. Mark checkboxes “ASP.NET Profiler” and “Code Coverage”. Move cursor to “Code Coverage” line and press Configure button or make double click on line. Assemblies selection window will be opened. Mark checkboxes that are located before assemblies about what you want code coverage reports and apply settings. Save your project and close Visual Studio. Run Visual Studio as Administrator and run tests. NB! Select Test => Run => Tests in Current Context from menu. When tests are run you can open code coverage results by selecting Test => Windows => Code Coverage Results from menu. Here you can see my example test results. Visual Studio 2010 Test Results window. All my tests passed this time. :) Click on image to see it at original size.  And here are the code coverage results. Visual Studio 2101 Code Coverage Results. I need a lot more tests for sure. Click on image to see it at original size.  As you can see everything was pretty simple. But it took me sometime to figure out how to get everything work as expected. Problems? You may face some problems when making code coverage work. Here is my short list of possible problems. Make sure you have all assemblies available for code coverage. In some cases it needs more libraries to be referenced as you currently have. By example, I had to add some more Enterprise Library assemblies to my project. You can use EventViewer to discover errors that where given during testing. Make sure you selected all testable assemblies from Code Coverage settings like shown above. Otherwise you may get empty results. Tests with code coverage are slower because we need ASP.NET profiler. If your machine slows down then try to free more resources.

• Types of semantic bugs, logic errors [closed]

  - by C-Otto

  I am a PhD student and currently focus on automatically finding instances of new types of bugs in (Java) programs that cannot be found by existing tools like FindBugs. The existing tool currently is used to prove/disprove termination of (Java) programs. I have some ideas (see below), but I could need more input from you (experienced programmers, potential users of my tool). What kind of bugs do you wish to find? What types of bugs exist and might be suitable for my analysis? One strength of the approach I use is detailled information about the heap. So in contrast to FindBugs, I can work with knowledge of the form "variable x and variable y are disjoint on the heap" or "variable z is not cyclic". It is also possible to see if a method might have side effects (and if so, which variables may/may not be affected by it). Example 1: Vacuous call: Graph graphOne = createGraph(); Graph graphTwo = createGraph(); Node source = graphTwo.getRootNode(); for (Node n : graphOne.getNodes()) { if (areConnected(source, n)) { graphTwo.addNode(n); } } Imagine createGraph() creates a fresh graph, so that graphOne and graphTwo are disjoint on the heap. Then, because source is taken from graphTwo instead of graphOne, the call to areConnected always returns false. In this situation I could find out that the call areConnected is useless (because it does not have any side effect and the return value always is false) which helps finding the real bug (taking source from the wrong graph). For this the information that x and y are disjoint (because graphOne and graphTwo are disjoint) is crucial. This bug is related to calling x.equals(y) where x and y are objects of different classes. In this scenario, most implementations of equals() always return false, which most likely is not the intended result. FindBugs already finds this bug (hardcoded to equals(), semantics of implementation is not checked). Example 2: Useless code: someCode(); while (something()) { yetMoreSomething(); } moreCode(); In the case that the loop (so the code in something() and yetMoreSomething()) does not modify anything visible outside the loop, it does not make sense to run this code - the program has the same behaviour as someCode(); moreCode() (i.e., without the loop). To find this out, one needs detailled information about the side effects of the (possibly useless) code. If I can prove that the code does not have any side effect that can be observed afterwards (in the example: in moreCode() or later), then the code indeed is useless. Of course, here Input/Output of any form must be seen as a side effect, so that a System.out.println(...) is not considered useless. Example 3: Ignored return value: Instead of x = foo(); and making use of x, the method is called without storing the result: foo();. If the method does not have any side effect, its invocation is useless and can be dropped. Most likely, the bug here is that the returned value should have been used. Here, too, detailled information about side effects are needed. Can you think of similar types of bugs that might be detected (only) with detailled information about the heap, side effects, semantics of called methods, ...? Did you encounter bugs related to the ones shown below in "real life"? By the way, the tool is AProVE and Java related publications can be found on my homepage. Thanks a lot, Carsten

• Is there a PowerShell code formatter / pretty printer?

  - by Sleepless

  I'm looking for a source code beautifyer for PowerShell programs. Ideally, it would be CLI based, but any solution is acceptable. I would like to avoid configuring a generic pretty printer tool; I'd like a solution that works for PowerShell out of the box. Is there such a thing?

• OWB 11gR2 &ndash; Flexible and extensible

  - by David Allan

  The Oracle data integration extensibility capabilities are something I love, nothing more frustrating than a tool or platform that is very constraining. I think extensibility and flexibility are invaluable capabilities in the data integration arena. I liked Uli Bethke's posting on some extensibility capabilities with ODI (see Nesting ODI Substitution Method Calls here), he has some useful guidance on making customizations to existing KMs, nice to learn by example. I thought I'd illustrate the same capabilities with ODI's partner OWB for the OWB community. There is a whole new world of potential. The LKM/IKM/CKM/JKMs are the primary templates that are supported (plus the Oracle Target code template), so there is a lot of potential for customizing and extending the product in this release. Enough waffle... Diving in at the deep end from Uli's post, in OWB the table operator has a number of additional properties in OWB 11gR2 that let you annotate the column usage with ODI-like properties such as the slowly changing usage or for your own user-defined purpose as in Uli's post, below you see for the target table SALES_TARGET we can use the UD5 property which when assigned the code template (knowledge module) which has been modified with Uli's change we can do custom things such as creating indices - provides The code template used by the mapping has the additional step which is basically the code illustrated from Uli's posting just used directly, the ODI 10g substitution references also supported from within OWB's runtime. Now to see whether this does what we expect before we execute it, we can check out the generated code similar to how the traditional mapping generation and preview works, you do this by clicking on the 'Inspect Code' button on the execution units code template assignment. This then  creates another tab with prefix 'Code - <mapping name>' where the generated code is put, scrolling down we find the last step with the indices being created, looks good, so we are ready to deploy and execute. After executing the mapping we can then use the 'Audit Information' panel (select the mapping in the designer tree and click on View/Audit Information), this gives us a view of the execution where we can drill into the tasks that were executed and inspect both the template and the generated code that was executed and any potential errors. Reflecting back on earlier versions of OWB, these were the kinds of features that were always highly desirable, getting under the hood of the code generation and tweaking bit and pieces - fun and powerful stuff! We can step it up a bit here and explore some further ideas. The example below is a daisy-chained set of execution units where the intermediate table is a target of one unit and the source for another. We want that table to be a global temporary table, so can tweak the templates. Back to the copy of SQL Control Append (for demo purposes) we modify the create target table step to make the table a global temporary table, with the option of on commit preserve rows. You can get a feel for some of the customizations and changes possible, providing some great flexibility and extensibility for the data integration tools.

• Show raw Text Code from a URL with CodePaste.NET

  - by Rick Strahl

  I introduced CodePaste.NET more than 2 years ago. In case you haven't checked it out it's a code-sharing site where you can post some code, assign a title and syntax scheme to it and then share it with others via a short URL. The idea is super simple and it's not the first time this has been done, but it's focused on Microsoft languages and caters to that crowd. Show your own code from the Web There's another feature that I tweeted about recently that's been there for some time, but is not used very much: CodePaste.NET has the ability to show raw text based code from a URL on the Web in syntax colored format for any of the formats provided. I use this all the time with code links to my Subversion repository which only displays code as plain text. Using CodePaste.NET allows me to show syntax colored versions of the same code. For example I can go from this URL: http://www.west-wind.com:8080/svn/WestwindWebToolkit/trunk/Westwind.Utilities/SupportClasses/PropertyBag.cs To a nicely colored source code view at this Url: http://codepaste.net/ShowUrl?url=http%3A%2F%2Fwww.west-wind.com%3A8080%2Fsvn%2FWestwindWebToolkit%2Ftrunk%2FWestwind.Utilities%2FSupportClasses%2FPropertyBag.cs&Language=C%23 which looks like this:   Use the Form or access URLs directly To get there navigate to the Web Code icon on the CodePaste.NET site and paste your original URL and select a language to display: The form creates a link shown above which has two query string parameters: url - The URL for the raw text on the Web language -  The code language used for syntax highlighting Note that parameters must be URL encoded to work especially the # in C# because otherwise the # will be interpreted by the browser as a hash tag to jump to in the target URL. The URL must be Web accessible so that CodePaste can download it and then apply the syntax coloring. It doesn't work with localhost urls for example. The code returned must be returned in plain text - HTML based text doesn't work. Hope some of you find this a useful feature. Enjoy…© Rick Strahl, West Wind Technologies, 2005-2011Posted in .NET   Tweet (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Books on Code Contracts in C# 4.0

  - by devoured elysium

  Altough I've known Code Contracts for some time, as I've used it a bit in Java, I would like to start using them in C#, now that they are part of C# 4.0. I am looking on learning material, books or vids. Altough tutorials are also welcome, I'd like to have something comprehensive to read, not the typical "here's how you use Requires and here's how you use Ensures". I am looking for something that really stands out in this area. Thanks

• Updated list of refactoring support for different IDEs

  - by Vargen

  Does anyone know of an updated list of refactoring support for different IDEs? How many of Fowlers refactorings have tool support in popular IDEs? And does any IDE use code smells to any greater extent? I guess one would have to use addons for some IDEs, so even if i did find an updated list of refactoring support for say Eclipse, that would probably not be representative.

• XCode code generation

  I was wondering if there is a tool (automator script or a third party) to generate code for simple scenarios like add another property. I don't like going to two or three places and write the same thing over and over again. instead I want to say "I want a new property of type int with name X" and it generates the lines in .h and .m files for me in one go.

  I recently began to start using functions to make casting easier on my fingers for one instance I had something like this ((Dictionary<string,string>)value).Add(foo); and converted it to a tiny little helper function so I can do this ToDictionary(value).Add(foo); Is this a code smell? (also I've marked this language agnostic even though my example is C#)

• Python Code Introspection and Analysis

  Hi, I am trying to write a Python code analyzer, and I am trying to avoid having to parse bare Python text files. I was hoping that once the Python compiler/interpreter parses the code there's a way to get to the object code or parse tree from within a running Python program. Is there anyway to do this? Thank you
