Add option to fail Publish Test Results task when test result file is not found

Question, Bug, or Feature?
Type: Feature

Enter Task Name: PublishTestResults@2

Environment

• Server - Azure Pipelines

Issue Description

I imagine it is a common pattern to have a test task (with continueOnError: true) followed by a publish task. I’ve run into the issue a couple times where we will have our test task fail due to setup issues (e.g. not test failures), but the junit output file will not be published. The PublishTestResults task will warn it cannot find the file, but it will not fail the task. I find myself relying heavily on failTaskOnFailedTests: true, and wish that I could make this task fail if no output files are found.

Task logs

For our build setup see here. This particular log actually brings up another issue, where failing when the output cannot be parsed would also be nice. I don’t think we have a log with the issue I described at the moment, but both things have occurred.

Hi - is this something you would accept a contribution on? This would be incredibly useful for me and looking at the code it seems like it would be fairly straightforward to implement.
