Function outFile

log/buffered_test.go:135–140

outFile creates a real OS file for testing. We cannot use stdout/stderr since we need to read the contents afterwards to validate, and we have to write to a file to benchmark the impact of write() syscalls.

(b *testing.B)

// We cannot use stdout/stderr since we need to read the contents afterwards to validate, and we have to write to a file
// to benchmark the impact of write() syscalls.
func outFile(b *testing.B) *os.File {
	f, err := os.CreateTemp(b.TempDir(), "buffered*")
	require.NoErrorf(b, err, "cannot create test file")

	return f
}
