Data Collector Errors Cause TRX Result to be Failed

[hankweber]

We have tests where all of the tests pass, but there are data collector errors which then cause the overall result of the trx file to be marked as failed. Is there a way to bypass this logic and treat data collector errors as warnings?

[nohwnd]

I don't think there is a generic option to treat all collector errors as warnings. Is there a specific collector that you are having problems with? Maybe they have an option for this.

I think I have the same thing here. I run a test suite twice (sequentially) firstly targeting net8.0, then net462. Locally everything works, trx files are created with no errors, but in my CI run Blame works fine on the first test run (net8.0) but crashes on net462 after every tests passed.

This is my dotnet setup:

        DotNetTest(s => s
                    .SetProjectFile(E2ETestsProjectFile)
                    .SetConfiguration(Configuration)
                    .EnableNoBuild()
                    .SetFramework("net8.0")
                    .SetLoggers("console;verbosity=detailed")
                    .SetProcessArgumentConfigurator(args => args.Add($"--blame-hang-timeout 5m --logger:trx;LogFileName={dateTimeNow}_net8_0_test_results.trx"))
                );

        DotNetTest(s => s
                    .SetProjectFile(E2ETestsProjectFile)
                    .SetConfiguration(Configuration)
                    .EnableNoBuild()
                    .SetFramework("net462")
                    .SetLoggers("console;verbosity=detailed")
                    .SetProcessArgumentConfigurator(args => args.Add($"--blame-hang-timeout 5m --logger:trx;LogFileName={dateTimeNow}_net462_test_results.trx"))
                ); 

This is my error:

22:31:41 [ERR] The active test run was aborted. Reason: Test host process crashed
22:31:41 [DBG] Data collector 'Blame' message: The specified inactivity time of 5 minutes has elapsed. Collecting hang dumps from testhost and its child processes.
  Error: Data collector 'Blame' message: Data collector caught an exception of type 'System.IO.FileNotFoundException': 'Collect dump was enabled but no dump file was generated.'. More details: Blame: Collecting hang dump failed with error...
22:31:41 [ERR] Data collector 'Blame' message: Data collector caught an exception of type 'System.IO.FileNotFoundException': 'Collect dump was enabled but no dump file was generated.'. More details: Blame: Collecting hang dump failed with error...

  Error: Test Run Aborted.
 22:31:41 [ERR] Test Run Aborted.

 22:31:41 [DBG] Results File: /home/runner/work/Project/Tests/E2E/TestResults/20241106_222415_net462_test_results.trx

So the trx is created, my 7 tests passed, but the test run is marked as failure. Am I missing something obvious?

NOTE: It was working fine when I only had one test run (only net8.0)

Not sure what to do with that..

Hmm, I actually saw something funny. I just noticed that locally, my runtime is Microsoft.NET\Framework64\v4.0.30319 (works fine) and in my linux CI, the runtime is mono/4.5 (hangs). testhost versions also don't match between net8 and net462

On my net8 run, the testhost.dll is using version 17.11.1 with runtime Microsoft.NETCore.App/8.0.10,

I also noticed at the end of the runs

And it just loops on the polling untill I reach my timeout. So the hang is actually caused by the test host and not my tests. Any idea what's happening? Any known issues between mono and your testhost?

@nohwnd Would you like that I create a new issue? Or do you need more info? Thank you! :)
