react-native - jest react-native 和 bugsnag 有这样的问题

Question

我尝试使用 Bugsnag 在 React-Native 上运行 Jest 单元测试，但出现错误:

 The error below may be caused by using the wrong test environment, see https://jestjs.io/docs/en/configuration#testenvironment-string.
    Consider using the "jsdom" test environment.
    
    ReferenceError: window is not defined
      1 | import React from 'react';
    > 2 | import Bugsnag from '@bugsnag/react-native';

Answer 1

对我有用的解决方案:

我们需要将模拟 bugsnag 拦截器添加到 jestSetupFile.js

jest.mock('@bugsnag/react-native', () => ({
  use(plugin) {
    const boundary = plugin.init();
    // we don't need the error boundary to swallow the errors, we want jest see them and fail the test
    delete boundary.prototype.componentDidCatch;
    return boundary;
  }
}));
