Method InListFold

string.go:418–461

InListFold succeeds if the string is equal to one of the values from given list of strings after applying Unicode case-folding (so it's a case-insensitive match). Example: str := NewString(t, "Hello") str.InListFold("hEllo", "Goodbye")

(values ...string)

//	str := NewString(t, "Hello")
//	str.InListFold("hEllo", "Goodbye")
func (s *String) InListFold(values ...string) *String {
	opChain := s.chain.enter("InListFold()")
	defer opChain.leave()

	if opChain.failed() {
		return s
	}

	if len(values) == 0 {
		opChain.fail(AssertionFailure{
			Type: AssertUsage,
			Errors: []error{
				errors.New("unexpected empty list argument"),
			},
		})
		return s
	}

	var isListed bool
	for _, v := range values {
		if strings.EqualFold(s.value, v) {
			isListed = true
			break
		}
	}

	if !isListed {
		valueList := make([]interface{}, 0, len(values))
		for _, v := range values {
			valueList = append(valueList, v)
		}

		opChain.fail(AssertionFailure{
			Type:     AssertBelongs,
			Actual:   &AssertionValue{s.value},
			Expected: &AssertionValue{AssertionList(valueList)},
			Errors: []error{
				errors.New("expected: string is equal to one of the values (if folded)"),
			},
		})
	}

	return s
}

// NotInListFold succeeds if the string is not equal to any of the values from given
// list of strings after applying Unicode case-folding (so it's a case-insensitive match).
