type TestLogger added in v0.19.0 

type TestLogger struct {
	// contains filtered or unexported fields
}

TestLogger is a logger for tests. It buffers output and only writes the output if the test fails or output is explicitly turned on. The purpose of this logger is to allow Go test to run with the verbose flag without printing logs. The verbose flag is useful since it streams test progress, but also printing logs makes the output too verbose.

You can also add prefixes that are prepended to each log message, for extra logging context.

This is implemented as a hierarchy of loggers, with children flushing log entries back to parents. This works because t.Cleanup() processes entries in LIFO order, so children always flush first.

Obviously this logger should never be used in production systems.
