Code Coverage and the Auto-Build

[Steve Barker]

Hi all,

I have a team project with continuous integration enabled. I have enabled
running of the unit tests when the build fires. I originally enabled running
of tests in a list, using the TFSBuild.proj file as follows:

<MetaDataFile Include="$(BuildProjectFolderPath)/../../Test/Test.vsmdi">
<TestList>Main</TestList>
</MetaDataFile>

…which worked fine, and produced code coverage metrics. Then I decided to
extend this to include all tests in any DLL called “*test*.dll”, so that
tests that developers forget to add to the Main test list would also be run,
by including the following additional command:

<TestContainer Include="$(OutDir)\%2aTest%2a.dll" />

This works well, so I decided that I should take out the MetaDataFile
section altogether and just use the TestContainer tag, as this would ensure
that all tests would be run and no tests would be repeated.

Code coverage metrics are calculated when tests are run using the
MetaDataFile tag, but unfortunately, the coverage is not calculated when
using just TestContainer. Is there something I need to enable/change to allow
calculation of code coverage metrics when using just TestContainer?

Many thanks,

Steve.

Hi Steve,

Thanks for your post.

If your TFS version is 2008, please follow the steps below to enable code
coverage:

1. Open build definition (TFSBuild.proj file) of your project
2. In PropertyGroup, add a property element as below:
<RunConfigFile>Location to testrunconfig file</RunConfigFile>
For example: if the testrunconfig file is located at server path:
$TeamProject1\Solution1\LocalTestRun.testrunconfig, it should be configured
in RunConfigFile element as:
$(SolutionRoot)\Solution1\LocalTestRun.testrunconfig.
Before that, you must configure the testrunconfig to enable code coverage.
3. Save the TFSBuild.proj and check into the server.
4. Trigger a build and you will see the code coverage in the build report.

In addition, if you encounter any error after adding the RunConfigFile
property. Please open the BuildLog.txt file and search for "Mstest.exe".
Checking if it has switch "/runconfig:" and if the path after it is the
correct path of testrunconfig file. Or you can directly send the
BuildLog.txt file to my email box so that I can check them for you.

Please let me know if there is anything unclear. I will try my best to
support

I think this problem is related to the other problem we're discussing, so
I'll send the files now...
