小编Cof*_*tte的帖子

我正在开发一个使用 Wea​​therAPI 的应用程序。我目前无法实施一些工作测试。我尝试遵循 ResoCoders 指南（https://resocoder.com/2019/11/29/bloc-test-tutorial-easier-way-to-test-blocs-in-dart-flutter/）并实际实现了所有状态，块（我用 Cubit 代替）、类、函数……几乎相同。

这是我的测试代码：

blocTest<WeatherCubit, WeatherBaseState>(
      'Cubit emits WeatherLoaded',
      build: () {
        return WeatherCubit(weatherRepository: mockWeatherRepository);
      },
      act: (WeatherCubit cubit) => cubit.getWeather(),
      expect: () => [
        WeatherLoaded(
            temperature: temperature,
            ...
            lat: lat,
            lon: lon)
      ],
    );

这是我从调试控制台得到的错误信息：

Expected: [Instance of 'WeatherLoaded']
  Actual: [Instance of 'WeatherLoaded']
   Which: at location [0] is <Instance of 'WeatherLoaded'> instead of <Instance of 'WeatherLoaded'>
