NUnit in Team Foundation Build

Not everyone have embraced Microsofts testing platform, but prefer to use other tools for unit testing, for instance NUnit. Because this is such a common scenario there is lots of information and components to help with integrating NUnit in Team Foundation Build.

The easiest solution is to use two add-on components. MSBuild Community Tasks to make configuration easier and NUnit for Team Build to integrate the testresults in the build log and get the results in reports. Both of these components are open source and free to download.

Begin with installing NUnit, MSBuild Community Tasks and NUnit for Team Build. After that only some changes in TFSBuild.proj are needet to get a really nice integration of NUnit in Team Foundation Server.

Import MSBuild Community Tasks by adding the following row:

<Import Project="$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.targets" />

Now we have the possibility to use every task that is defined in the imported file, but the one we are interested in here is only the one that concerns NUnit. To add an NUnit task, add the following at the bottom of TFSBuild.proj:

<Target Name="AfterCompile">
    <!-- Create a Custom Build Step -->
    <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Name="NUnitTestStep" Message="Running Nunit Tests">
        <Output TaskParameter="Id" PropertyName="NUnitStepId" />
    </BuildStep>

    <!-- Get Assemblies to test -->
    <ItemGroup>
        <TestAssemblies Include="$(OutDir)\**\cs-*.dll" />
    </ItemGroup>

    <!-- Run NUnit and check the result -->
    <NUnit ContinueOnError="true" Assemblies="@(TestAssemblies)" OutputXmlFile="$(OutDir)nunit_results.xml" ToolPath="$(ProgramFiles)\Nunit 2.4.7\bin\">
        <Output TaskParameter="ExitCode" PropertyName="NUnitResult" />
    </NUnit>
    <BuildStep Condition="'$(NUnitResult)'=='0'" TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(NUnitStepId)" Status="Succeeded" />
    <BuildStep Condition="'$(NUnitResult)'!='0'" TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(NUnitStepId)" Status="Failed" />

    <!-- Regardless of NUnit success/failure upload the results to TFS. -->
    <Exec Command="&quot;$(MSBuildProjectDirectory)\NUnitTFS.exe&quot; -n &quot;$(OutDir)nunit_results.xml&quot; -t &quot;$(TeamProject)&quot; -b &quot;$(BuildNumber)&quot; -f &quot;%(ConfigurationToBuild.FlavorToBuild)&quot; -p &quot;%(ConfigurationToBuild.PlatformToBuild)&quot; -x &quot;$(MSBuildProjectDirectory)\NUnitToMSTest.xslt&quot;" />

    <!-- If NUnit failed it's time to error out -->
    <Error Condition="'$(NUnitResult)'!='0'" Text="Unit Tests Failed" />
</Target>

If you would like to run the test with a specific App.config like a testrunconfig file, it is possible to put the App.config file in the Source Control tree in the same directory as TFSBuild.proj. By running a copy command in the test task the special App.config could be copied with the current build. Add the following row for the concerned test DLL:s before the NUnit step:

<Exec Command="copy &quot;$(MSBuildProjectDirectory)\App.config&quot; &quot;$(OutDir)\MyTest.dll.config&quot; /y" />

Note the /y attribute which means that an existing file will be overwritten automatically.

The Cornball goes to Brunch with Chaplin

Lately I've been working pretty hard on different projects but not really stumbling upon anything blogworthy. The most recent project is quite interesting though, a single page, touch friendly, web application using the latest and greatest technologies. We've ended up with using Brunch with Chaplin , which is a very neat way of setting up a Backbone based single page web project with Brunch and Chaplin . Aside from this, I have my own little project that has lived on for almost 15 years already, The Cornball . From being a plain Windows application written i C an Win32 API, it has been ported to .NET using WPF, and is currently a Silverlight application hosted on Windows Azure. I could not find a better time to reanimate this project and create a new web based version, touch friendly, super optimized, awesome in any way. So I did... So please follow my journey at Github . It's going to take a while, I assure you, but I already have some ground work done. Meanwhile,...

Bindable RichTextBox with HTML conversion in WPF

In WPF , the RichTextBox  control is not really like other controls. Due to its flexible nature, there is no built in way of binding a property to the content. In this case, I wanted a simple  RichTextBox  control with a binding to an HTML formatted string to be able to use the built-in formatting features of the  RichTextBox  and allow users to create simple HTML formatted content. First, doing the conversion on-the-fly proved to have major performance issues, so I ended up binding the content to a XAML string. The XAML to HTML conversion can be performed at any time. I created a UserControl with a bindable Text-property. The view contains a  RichTextBox  control. <RichTextBox x:Name="richTextBox" TextChanged="OnRichTextBoxChanged"> The source code for the user control contains the Text property and the methods to handle the binding. public static readonly DependencyProperty TextProperty = DependencyProperty.Register( "Te...

Using ASP.NET MVC with MEF

I wrote this post almost a year ago, but never published it for some reason. Anyway, here is a little MVC/MEF magic. By default a controller in MVC must have a parameterless constructor. When using MEF a good practice is to inject the services via constructor parameters. These two in combination obviously creates an issue where the following scenario will not work out of the box, since there is no parameterless constructor for  MVC  to use. Note that the PartCreationPolicy is set to NonShared since a new controller have to be initialized for each request. [Export] [PartCreationPolicy(CreationPolicy.NonShared)] public class HomeController : Controller {     private readonly IServiceClient _service;     [ImportingConstructor]     public HomeController(IServiceClient service)     {         _service = service;     }     public ActionResult Index()     {         ...
