To create a unit test for asynchronous code using Dart Test, you can follow these steps:
import 'package:test/test.dart';
import 'dart:async';
async
function:void main() {
test('test asynchronous code', () async {
// Write your test code here
});
}
test
function. You can use the Completer
class to create a future that completes asynchronously:void main() {
test('test asynchronous code', () async {
Completer completer = new Completer();
// Use the Timer class to simulate asynchronous code that completes in 2 seconds
Timer(Duration(seconds: 2), () {
completer.complete();
});
// Use the await keyword to wait for the future to complete
await completer.future;
// Write your expectations here
expect(1+1, equals(2));
});
}
expect
function, as shown above.Note: Asynchronous unit tests in Dart Test should always begin with "test" to be executed.
