我一直在尝试为我的 cubit 设置单元测试,但 bloc 测试似乎有问题。只是尝试检查值的初始状态在常规测试中效果很好,但是一旦我尝试使用 bloc 测试进行相同的事情,它就会吐出失败,实际是 [0] 处的空列表,我不确定我做错了什么。互联网上没有任何东西对这个错误有帮助。
//passes
test('initial state of SettingsCubit', () {
expect(
settingsCubit.state,
SettingsState(
notificationsEnabled: false,
gpsEnabled: false,
celsiusEnabled: false,
expandNavigation: false,
breakingNewsNotifications: false,
trendingNotifications: false,
liveRemindersNotifications: false,
sportsNotifications: false));
});
//fails
blocTest(
'initial state of SettingsCubit',
build: () => SettingsCubit(),
expect: () => [
SettingsState(
expandNavigation: false,
gpsEnabled: false,
celsiusEnabled: false,
notificationsEnabled: false,
breakingNewsNotifications: false,
trendingNotifications: false,
liveRemindersNotifications: false,
sportsNotifications: false,
)
],
);
错误:
