Why is my VSTest Runner test results file not being written to where I configured it?

Hi David,

If you take a look at the agent logs what do you see? The directory may not have been able to be created or move the result to the result directory. 

Take a look at the logs around 12-Dec-2017 13:38:33 and see if there are any errors related to the directory you specified.  Let me know what you find.

Cheers,

Branden

vstest.console.exe doesn't allow to specify output filename so Bamboo executes it at temporary folder and then copies generated *.trx file to folder specified by user. It's not clear from build logs, but it works like this from source code perspective: https://bitbucket.org/atlassian/bamboo-dotnet-plugin/src/d2788e3b641ccd5e5895d1adc7f115c1046df5f2/src/main/java/com/atlassian/bamboo/plugin/dotnet/tests/vstest/VSTestRunnerTaskType.java?at=default&fileviewer=file-view-default

According to the --help output on my version of vstest.console.exe you can specify the trx file name with the /logger option:

--logger|/logger:<Logger Uri/FriendlyName>
Specify a logger for test results. For example, to log results into a
Visual Studio Test Results File (TRX) use /logger:trx[;LogFileName=<Defaults to unique file name>]
Creates file in TestResults directory with given LogFileName.

So the command line:

"C:\Program Files (x86)\Microsoft Visual Studio\2017\TestAgent\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe" /logger:trx;LogFileName=MyResults.trx org.example.tests\bin\Debug\org.example.tests.dll

Will create output in:

MyResults.trx

Important: Contary to the help output shown above, if no trx file name is specified none will be created!

Unfortunately the Java code linked to in the post does not seem to allow for a user specified trx file name:

command.add("/logger:Trx");

My guess is that changing this line to the logical equivalent of the following psudo code

command.add("/logger:Trx;<resultFileName>");

 i.e. adding the string ";<resultFileName>" part where a file is specified, or a suitable default if not, would create the desired trx file.

Update: We found that using the vstest.console.exe installed as part of a Visual Studio install fixed our problems.
