testequal

В этой задаче нужно реализовать 4 test helper'а, аналогичных функциям из testify:

func AssertEqual(t T, expected, actual interface{}, msgAndArgs ...interface{}) bool
func AssertNotEqual(t T, expected, actual interface{}, msgAndArgs ...interface{}) bool
func RequireEqual(t T, expected, actual interface{}, msgAndArgs ...interface{})
func RequireNotEqual(t T, expected, actual interface{}, msgAndArgs ...interface{})

Функции проверяют на равенство expected и actual и завершают тест, если проверка не прошла. msgAndArgs попадают в описание ошибки через fmt.Sprintf.

Пример использования:

func TestMath(t *testing.T) {
	AssertEqual(t, 1, 2, "1 == 2")
}

вывод теста:

=== RUN   TestMath
--- FAIL: TestMath (0.00s)
    math_test.go:43: not equal:
        expected: 1
        actual  : 2
        message : 1 == 2
FAIL
FAIL    gitlab.com/slon/shad-go/testequal 0.003s
FAIL

В отличие от testify реализация ограничивает набор типов, с которыми умеет работать:

1. Целые числа: int, int64 и др (см. тесты)
2. string
3. map[string]string
4. []int
5. []byte

Functions

func AssertEqual

func AssertEqual(t T, expected, actual interface{}, msgAndArgs ...interface{}) bool

AssertEqual checks that expected and actual are equal.

Marks caller function as having failed but continues execution.

Returns true iff arguments are equal.

func AssertNotEqual

func AssertNotEqual(t T, expected, actual interface{}, msgAndArgs ...interface{}) bool

AssertNotEqual checks that expected and actual are not equal.

Marks caller function as having failed but continues execution.

Returns true iff arguments are not equal.

func RequireEqual

func RequireEqual(t T, expected, actual interface{}, msgAndArgs ...interface{})

RequireEqual does the same as AssertEqual but fails caller test immediately.

func RequireNotEqual

func RequireNotEqual(t T, expected, actual interface{}, msgAndArgs ...interface{})

RequireNotEqual does the same as AssertNotEqual but fails caller test immediately.

Types

type T

type T interface {
	Errorf(format string, args ...interface{})
	Helper()
	FailNow()
}

T is an interface wrapper for *testing.T that contains only a small subset of methods.
