Conversation
Smoke tests were not running against the VSIX-packaged vstest.console that ships into Visual Studio. Add useVsixRunner: true to the data source attributes so these tests also validate the VSIX runner. - DiscoveryTests.MultipleSourcesDiscoverAllTests (Acceptance) - ExecutionTests.RunMultipleMSTestAssembliesOnVstestConsoleAndTesthostCombinations3 (Acceptance) - RunTests.RunAllTestsFromDlls (Library) - DiscoverTests.DiscoverTestsUsingDiscoveryEventHandler2AndTelemetryOptedIn (Library) DotnetTestTests.RunDotnetTestWithCsproj is skipped as it uses dotnet test, not vstest.console directly.
