# value_listenable_test

Assists in testing **ValueListenable** objects (ex: **ValueNotifier**).

## install

Added in your `pubspec.yaml` as **dev dependency**:

```yaml

dev_dependencies:

  value_listenable_test: any

```

## Examples

Listen the emits of ValueListenable:

```dart

 test('valueListenable Matcher', () {

     final counter = ValueNotifier(0);

     expect(counter, emitValues([2, 3, 5]));

     counter.value = 2;

     counter.value = 3;

     counter.value = 5;

   });

```

Also, you can use the test abstraction called **valueListenableTest**:

```dart

valueListenableTest(

  'Counter emits [1] when update method is called',

  build: () => Counter(),

  act: (notifier) => notifier.update(1),

  expect: () => [1],

);

```

That`s it!
