isBeforeOrSameMomentAs function
Validates that a DateTime is before or the same moment as date
.
This matcher has additional behavior when used in expectResponse, hasResponse, hasHeaders, hasBody: if the actual value is a String, it will attempted to be parsed into a DateTime first. If parsing fails, this matcher will fail.
expectResponse(response, 200, headers: {"x-timestamp": isBeforeOrSameMomentAs(DateTime())});
Implementation
Matcher isBeforeOrSameMomentAs(DateTime date) {
return predicate((DateTime d) => d.isBefore(date) || d == date,
"before or same moment as ${date.toIso8601String()}");
}
