Question

我正在尝试以开玩笑的方式测试Firebase云消息传递，但我的模拟功能有错误...

如何测试所有函数调用？

expect(jest.fn()).toHaveBeenCalled()
Expected mock function to have been called.

import { Sentry, SentrySeverity } from 'react-native-sentry';
import RNFirebase from 'react-native-firebase';
import Veery from 'react-native-veery';

export default function firebaseCloudMessaging() {
  try {
    const firebase = RNFirebase.app().messaging();

    firebase.getToken().then(Veery.setVeeryToken);

    firebase.getInitialNotification();

    firebase.onMessage(Veery.VeeryNotificationHandler);

    firebase.onTokenRefresh(Veery.setVeeryToken);
  } catch (error) {
    Sentry.captureException(error, { level: SentrySeverity.Error });
    console.warn('Error with firebaseCloudMessaging ', error);
  }
}

谢谢！

我的错误： 先前的模拟创建了多个模拟实例因此，当我尝试检查是否已调用模拟程序时，我在比较的是相同的函数，而不是相同的函数实例！

jest.mock('react-native-firebase', () => {
  const app = { messaging: () => messaging };

  const messaging = {
    getToken: jest.fn(() => Promise.resolve('myTokenMock')),
    getInitialNotification: jest.fn(),
    onMessage: jest.fn(),
    onTokenRefresh: jest.fn(() => Promise.resolve('myMockTokenRefresh')),
  };

return { app: () => app };
});

使用Jest测试Firebase云消息传递
