Reading runtime parameters in VSTest based C++ tests

Question

How can I read the runtime parameters passed to C++ unit tests when it is running under vstest.console.exe or as VSTest task in Azure DevOps build pipeline?

I am trying to read the runtime parameters set in .runsettings file or passed through overrideTestrunParameters but unable to find a way to do this.

Looks like TestContext is available only for C# based tests and not available to unmanaged C++ unit tests.

In Azure Devops, you could directly use the PowerShell task to read the runtime parameters in .runsettings file:

Here is an example:

test.runsettings

  <!-- Parameters used by tests at runtime -->
  <TestRunParameters>
    <Parameter name="webAppUrl" value="http://localhost" />
    <Parameter name="webAppUserName" value="Admin" />
    <Parameter name="webAppPassword" value="Password" />
  </TestRunParameters>

Pipeline PowerShell task InLine Script:

[xml]$DSConfig = gc "$(build.sourcesdirectory)/test.runsettings" #file path

# Select <parameters> nodes
$ParametersNode = $DSConfig.SelectNodes('//Parameter')


foreach($Node in $ParametersNode)
{
   echo  Name: $Node.name Value: $Node.value
  
}

Result:
