Function Error

assert/assertions.go:1648–1657

Error asserts that a function returned an error (i.e. not `nil`). actualObj, err := SomeFunction() assert.Error(t, err)

(t TestingT, err error, msgAndArgs ...interface{})

//	actualObj, err := SomeFunction()
//	assert.Error(t, err)
func Error(t TestingT, err error, msgAndArgs ...interface{}) bool {
	if err == nil {
		if h, ok := t.(tHelper); ok {
			h.Helper()
		}
		return Fail(t, "An error is expected but got nil.", msgAndArgs...)
	}

	return true
}

// EqualError asserts that a function returned an error (i.e. not `nil`)
// and that it is equal to the provided error.
