Function ErrorIsf

assert/assertion_format.go:161–166

ErrorIsf asserts that at least one of the errors in err's chain matches target. This is a wrapper for errors.Is.

(t TestingT, err error, target error, msg string, args ...interface{})

// ErrorIsf asserts that at least one of the errors in err's chain matches target.
// This is a wrapper for errors.Is.
func ErrorIsf(t TestingT, err error, target error, msg string, args ...interface{}) bool {
	if h, ok := t.(tHelper); ok {
		h.Helper()
	}
	return ErrorIs(t, err, target, append([]interface{}{msg}, args...)...)
}

// Eventuallyf asserts that given condition will be met in waitFor time,
// periodically checking target function each tick.
