MSBuild is the build system for Microsoft and Visual Studio. It is completely transparent in processing and building software, enabling developers to build products in development environments where Visual Studio is not present.

MSBuild uses a simple and extensible XML file format that is fully supported by Microsoft. It enables developers to fully describe what items need to be built and how they need to be built in different configurations. MS Build tasks are units of executable code to perform build operations. Once created, tasks can be shared among different developers to be reused in different projects.

This topic demonstrates how to integrate Telerik® JustMock with an MSBuild task. If you would like to learn more about MSBuild, refer to MSDN Library.

## How to Run Unit Tests from a MSBuild Task

1. Open your MSBuild project and under the Project node include JustMock targets file. This file is named JustMock.targets and can be found in the installation directory under the Libraries folder (by default C:\Program Files (x86)\Progress\Telerik JustMock\Libraries).

  <Import Project="JustMock.targets" />


Remember to change the path to the .targets file to the one specific for your system.

2. Add the following two tasks under the Project node to start and stop JustMock before and after the tests run, respectively:

<Target Name="BeforeTestConfiguration">
<JustMockStart />
</Target>

<Target Name="AfterTestConfiguration">
<JustMockStop />
</Target>


<JustMockStart LinkProfilers="JustTrace; Visual Studio 2012 Code Coverage/IntelliTrace" />

When you don't have the possibility for installing JustMock, you can setup MSBuild to run the profiler by providing the path to the profiler assembly of JustMock. The <JustMockStart/> MSBuild task has the attribute ProfilerPath, which must be set to the full path to the profiler DLL. Usually, there is a build variable that holds the absolute path to the source code root folder. If we assume that variable is called $(SourceDir), then we can set the profiler path like so: <JustMockStart ProfilerPath="$(SourceDir)\path\to\Telerik.CodeWeaver.Profiler.dll" />
