Below is a summarization created by an LLM (gpt-4-0125-preview). Be mindful of hallucinations and verify accuracy.

Why

The changes improve error handling and logging within the parseTestResults function. Specifically, they enhance the way panics and races are attributed to tests, introduce clearer error messages for various failure scenarios, and add error types for specific error conditions. These changes aim to make debugging and understanding test failures easier.

What

• runner/runner.go:
  • Enhanced error logging and handling in attributePanicToTest function to provide more specific error messages and introduced error types for different failure scenarios.
  • Changed log level from Warn to Error and added printing of error message when unable to attribute panic to a test.
  • Introduced several new error types (ErrFailedToAttributePanicToTest, ErrFailedToParseTimeoutDuration, ErrFailedToExtractTimeoutDuration, ErrDetectedLogAfterCompleteFailedAttribution, ErrDetectedTimeoutFailedParse, ErrDetectedTimeoutFailedAttribution) to clearly identify specific error conditions.
• runner/runner_test.go:
  • Adjusted tests to include cases for new error handling and checking specific error types (ErrFailedToAttributePanicToTest, ErrFailedToParseTimeoutDuration, ErrFailedToExtractTimeoutDuration, ErrDetectedLogAfterCompleteFailedAttribution, ErrDetectedTimeoutFailedParse, ErrDetectedTimeoutFailedAttribution).
