0011 Test Session Timeout

Summary

Allow user to specify timeout which will terminate a test session when it exceeds a given timeout.

Motivation

The test platform should have the ability for users to specify a test run level timeout which allows users to terminate a test session when it exceeds a given timeout. This ensures that resources are well consumed and test sessions are constrained to a set time.

Detailed Design

User would specify timeout using runsetting or through commandline.

User can specify timeout using runsettings as follows:

<RunSettings>
  <RunConfiguration>
     <!-- Specify timeout in milliseconds. A valid value should be greater than 0 -->
     <TestSessionTimeout>10000</TestSessionTimeout>
  </RunConfiguration>
</RunSettings>

User can specify timeout using commandline as follows:

vstest.console <testContainersList> -- RunConfiguration.TestSessionTimeout=10000

Overview of changes

Testplatform will cancel the current test run if it has exceeded given TestSessionTimeout. It will also make sure that testhost is getting test cancel request. Finally it will conclude the run with whatever test run till that point.

Exit Code of vstest.console

It will be a failed test and exit code will be 1
