Functions

func LogWriter

func LogWriter(t testing.TB) io.Writer

LogWriter builds and returns an io.Writer that writes messages to the given testing.TB. It ensures that each line is logged separately.

Any trailing buffered text that does not end with a newline is flushed when the test finishes.

The returned writer is safe for concurrent use from multiple parallel tests.

func LogWriterPrefixed

func LogWriterPrefixed(t testing.TB, prefix string) io.Writer

LogWriterPrefixed is a variant of LogWriter that prepends the given prefix to each line.
