Method ContainsFold

string.go:574–594

ContainsFold succeeds if string contains given Go string as a substring after applying Unicode case-folding (so it's a case-insensitive match). Example: str := NewString(t, "Hello") str.ContainsFold("ELL")

(value string)

//	str := NewString(t, "Hello")
//	str.ContainsFold("ELL")
func (s *String) ContainsFold(value string) *String {
	opChain := s.chain.enter("ContainsFold()")
	defer opChain.leave()

	if opChain.failed() {
		return s
	}

	if !strings.Contains(strings.ToLower(s.value), strings.ToLower(value)) {
		opChain.fail(AssertionFailure{
			Type:     AssertContainsSubset,
			Actual:   &AssertionValue{s.value},
			Expected: &AssertionValue{value},
			Errors: []error{
				errors.New("expected: string contains sub-string (if folded)"),
			},
		})
	}

	return s
}

// NotContainsFold succeeds if string doesn't contain given Go string as a substring
// after applying Unicode case-folding (so it's a case-insensitive match).
