manual_clock 1.0.0

A package for testing current time related code.

Manual Clock

This package is for testing current time related code.

The ManualClock class is a derived class of Clock.

With clock and fake_async libraries, you can test current time (clock.now()) related code. But inside fake async callback, you can't use await. Because of this restriction, Sometimes it is hard to test your code. With this library, you can test current time related code using await.

Getting started

pubspec.yaml

dev_dependencies:
  manual_clock: ^1.0.0

Usage

test('a test case', () async {
  await withManualClock((clock) async {
    final obj = ClassDependOnNow(...);
    clock.elapse(Duration(...));

    // You can use await inside callback
    final result = await obj.getResult();  
    expect(result, ...);
  },
  // optionally set initial time
  initialTime: DateTime(2000, 1, 1));
});
