func AssertEqual ¶

func AssertEqual[T any](t *testing.T, msg string, want, got T)

AssertEqual checks if the given two values are the same. AssertEqual compares want and got using reflect.DeepEqual. See https://go.dev/wiki/TestComments

func AssertEqualErr ¶

AssertEqualErr checks if the given two errors are the same. Errors are checked by following order and considered the same when one of them returned true.

• Compare pointer: want == got
• Compare error: errors.Is(got, want)
• Compare message: want.Error() == got.Error()

func ReplaceRandReader ¶

func ReplaceRandReader(r io.Reader) (done func())

ReplaceRandReader replaces rand.Reader with r. Do not run test parallel when using this. Call done after the test finished to set original rand.Reader.

done := ztesting.ReplaceRandReader(YourReader)
defer done()

func ReplaceStderr ¶

func ReplaceStderr() (r *os.File, done func())

ReplaceStderr replaces os.Stderr and return reader. Do not run test parallel when using this. Call done after the test finished to set original Stderr.

r, done := ztesting.ReplaceStderr()
defer done()

func ReplaceStdin ¶

func ReplaceStdin() (w *os.File, done func())

ReplaceStdin replaces os.Stdin and return writer. Do not run test parallel when using this. Call done after the test finished to set original Stdin.

w, done := ztesting.ReplaceStdin()
defer done()

func ReplaceStdout ¶

func ReplaceStdout() (r *os.File, done func())

ReplaceStdout replaces os.Stdout and return reader. Do not run test parallel when using this. Call done after the test finished to set original Stdout.

r, done := ztesting.ReplaceStdout()
defer done()
