Function EqualError

assert/assertions.go:1614–1630

EqualError asserts that a function returned an error (i.e. not `nil`) and that it is equal to the provided error. actualObj, err := SomeFunction() assert.EqualError(t, err, expectedErrorString)

(t TestingT, theError error, errString string, msgAndArgs ...interface{})

//	actualObj, err := SomeFunction()
//	assert.EqualError(t, err,  expectedErrorString)
func EqualError(t TestingT, theError error, errString string, msgAndArgs ...interface{}) bool {
	if h, ok := t.(tHelper); ok {
		h.Helper()
	}
	if !Error(t, theError, msgAndArgs...) {
		return false
	}
	expected := errString
	actual := theError.Error()
	// don't need to use deep equals here, we know they are both strings
	if expected != actual {
		return Fail(t, fmt.Sprintf("Error message not equal:\n"+
			"expected: %q\n"+
			"actual  : %q", expected, actual), msgAndArgs...)
	}
	return true
}

// ErrorContains asserts that a function returned an error (i.e. not `nil`)
// and that the error contains the specified substring.
