func AssertEqual ¶

func AssertEqual[T comparable](t *testing.T, errReason string, want, got T)

AssertEqual checks if the given two values are the same. See also https://go.dev/wiki/TestComments

func AssertEqualErr ¶

func AssertEqualErr(t *testing.T, errReason string, want, got error)

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 AssertEqualMap ¶

func AssertEqualMap[M1, M2 ~map[K]V, K, V comparable](t *testing.T, errReason string, want M1, got M2)

AssertEqualMap checks if the given two maps are the same using maps.Equal. errReason can be a expression for fmt.Sprintf(errReason, want, got). See also https://go.dev/wiki/TestComments

func AssertEqualSlice ¶

func AssertEqualSlice[S ~[]E, E comparable](t *testing.T, errReason string, want, got S)

AssertEqualSlice checks if the given two slices are the same using slices.Equal. See also https://go.dev/wiki/TestComments

func AssertNotEqual ¶

func AssertNotEqual[T comparable](t *testing.T, errReason string, check, got T)

AssertNotEqual checks if the given two values are not same. See also https://go.dev/wiki/TestComments

func ReplaceRandReader ¶

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

ReplaceRandReader replaces rand.Reader to the r. Do not run test parallel when using this. Call done function returned from it when tests are completed.

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 function returned from it when tests are completed.

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 function returned from it when tests are completed.

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 function returned from it when tests are completed.

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