Function Len

internal/testify/assert/assertions.go:794–807

Len asserts that the specified object has specific length. Len also fails if the object has a type that len() not accept. assert.Len(t, mySlice, 3)

(t TestingT, object interface{}, length int, msgAndArgs ...interface{})

//
//	assert.Len(t, mySlice, 3)
func Len(t TestingT, object interface{}, length int, msgAndArgs ...interface{}) bool {
	if h, ok := t.(tHelper); ok {
		h.Helper()
	}
	l, ok := getLen(object)
	if !ok {
		return Fail(t, fmt.Sprintf("\"%v\" could not be applied builtin len()", object), msgAndArgs...)
	}

	if l != length {
		return Fail(t, fmt.Sprintf("\"%v\" should have %d item(s), but has %d", object, length, l), msgAndArgs...)
	}
	return true
}

// True asserts that the specified value is true.
