Testing

Overriding providers#

Consider the next provider

final loginProvider = StateProvider<LoginController, LoginState>(
  (_) => LoginController(),
);

So, maybe in one test you need mock the LoginController behavior then you can use the overrideProvider method.

import 'package:mocktail/mocktail.dart';

final loginProvider = StateProvider<LoginController, LoginState>(
  (_) => LoginController(),
);

class MockLoginController extends Mock implements LoginController {}

Next before your test you can use the setUp method.

setUp((){
  loginProvider.overrideProvider(
    (_) => MockLoginController(),
  );
});

Cleaning your providers#

Before or after each test you will need the default state of all SimpleNotifier or StateNotifier. So you can use ProviderScope.clear(); to clear all provider saved in the ProviderScope.

setUp((){
  ProviderScope.clear();
});

or 


tearDown((){
  ProviderScope.clear();
});
