This will break $res = & ./test.ps1 (when the run fails) because exit will only exit the script, so in that case $res would contain the object prior to this PR. See https://github.com/pester/Pester/issues/2300#issuecomment-1426897882

But is this intended to work or just luck? I'd lean towards merging this, because Run.Exit says Exit with non-zero exit code when the test run fails. so I wouldn't expect to be able to post-process anything.

Exit in powershell is defined as exiting the script with the error code, not the engine. So $res = & ./test.ps1 should imho assign the value, rather than not.

Or am I misinterpreting what you are saying here?

I think we agree. There's two sides here and I'm not sure if fixing one is worth breaking the other, which is why I left this without ready to merge. The question is if anyone's gonna be missing the part being broken. Current behavior:

Catching output from script Running $res = & ./test.ps1 you'd keep the pipeline and result-object even on failure. But would anyone process it for a failed run while using -CI/Run.Exit? Or would they immediately check $? -eq $false and break? Personally I'd use $res = Invoke-Pester inside the test.ps1 script (and that script would exit either way), not catch the script output itself. However I can't exclude that others might do something else.

Calling Pester directly Users invoking Pester directly would get their process terminated by exit and the result-object would be printed as string (noise) in the CI-logs etc. Unless they do called Pester through a child-process like $a = pwsh -noprofile -command { Invoke-Pester ..., which seems unlikely.

Close or keep? I agree with your reasoning above that neither case is preferable, so maybe just keep the current one and close this?

I'd say merge in v6. Easy rollback if necessary.

I'm struggling to see when someone would combine Run.Exit with processing script output. If so they could just drop Run.Exit and add a check in their script to get the previous behavior.
