func ItNotPanics

func ItNotPanics[T any](t *testing.T, fn func() T, message ...any) (out T)

ItNotPanics is an assertion helper.

It will test that a given function panics using a recovery.

func ItPanics

func ItPanics(t *testing.T, fn func(), message ...any)

ItPanics is an assertion helper.

It will test that a given function panics using a recovery.

func ItsAll

func ItsAll[T any](t *testing.T, values []T, fn func(T) bool, message ...any)

ItsAll is an assertion helper.

It will test that all values in the slice match the filter.

func ItsAny

func ItsAny[T any](t *testing.T, values []T, fn func(T) bool, message ...any)

ItsAny is an assertion helper.

It will test that any value in the slice matches the filter.

func ItsEmpty

func ItsEmpty(t *testing.T, v any, message ...any)

ItsEmpty is an assertion helper.

It will test that the given value is empty, printing the value if the value has a string form.

func ItsEpsilon

func ItsEpsilon[T IEpsilon](t *testing.T, actual, expected, epsilon T, message ...any)

ItsEpsilon asserts that two numbers are within an epsilon of each other.

func ItsEqual

func ItsEqual(t *testing.T, expected, actual any, message ...any)

ItsEqual is a test helper to verify that two arguments are equal.

You can use it to build up other assertions, such as for length or not-nil.

func ItsFalse

func ItsFalse(t *testing.T, expectedFalse bool, message ...any)

ItsFalse is a helper that tests a value expected to be true.

func ItsInTimeDelta

func ItsInTimeDelta(t *testing.T, t0, t1 time.Time, d time.Duration, userMessage ...any)

ItsInTimeDelta is a test helper to verify that two times are within a given duration.

It works strictly in an absolute sense, that is if one time is before another, or vice versa the delta will always be positive.

func ItsLen

func ItsLen(t *testing.T, v interface{}, expected int, message ...any)

ItsLen is an assertion helper.

It will test that the given value has a given length.

ItsNil is an assertion helper.

It will test that the given value is nil, printing the value if the value has a string form.

func ItsNone

func ItsNone[T comparable](t *testing.T, values []T, fn func(T) bool, message ...any)

ItsNone is an assertion helper.

It will test that none of the values in the slice match the filter.

func ItsNotEmpty

func ItsNotEmpty(t *testing.T, v any, message ...any)

ItsNotEmpty is an assertion helper.

It will test that the given value is not empty.

func ItsNotEqual

func ItsNotEqual(t *testing.T, expected, actual any, message ...any)

ItsNotEqual is a test helper to verify that two arguments are not equal.

You can use it to build up other assertions, such as for length or not-nil.

func ItsNotInTimeDelta

func ItsNotInTimeDelta(t *testing.T, t0, t1 time.Time, d time.Duration, userMessage ...any)

ItsNotInTimeDelta is a test helper to verify that two times are within a given duration.

It works strictly in an absolute sense, that is if one time is before another, or vice versa the delta will always be positive.

func ItsNotNil

func ItsNotNil(t *testing.T, v any, message ...any)

ItsNotNil is an assertion helper.

It will test that the given value is not nil.

func ItsNotZero

func ItsNotZero(t *testing.T, actual any, message ...any)

ItsNotZero is a test helper to verify that an argument is not zero.

func ItsTrue

func ItsTrue(t *testing.T, expectedTrue bool, message ...any)

ItsTrue is a helper that tests a value expected to be true.

func ItsZero

func ItsZero(t *testing.T, actual any, message ...any)

func Len

func Len(object any) int

Len returns the length of a given reference if it is a slice, string, channel, or map.

func Nil

func Nil(object any) bool

Nil returns if a given reference is nil, but also returning true if the reference is a valid typed pointer to nil, which may not strictly be equal to nil.
