reactjs - Jest 问题 - ReactElement.js : Failed to get mock metadata

Question

我有一个非常简单的测试

/** @jsx React.DOM */
var store = require('../simpleStore');
var TestUtils = require('react/addons').addons.TestUtils;

describe("my tests",function(){
  it('simple test',function(){
     var x=10,
        y=20;
     expect(x).not.toBe(y);
  })
})

只要我不需要 TestUtils，测试就可以正常工作。当我添加任何 node_module 引用时，我开始看到以下错误

Using Jest CLI v0.8.0, jasmine1
FAIL  build/stores/__tests__/simple-test.js

● Runtime Error

Error: ../stores/__tests__/simple-test.js:
../../node_modules/react/addons.js:

npm ERR! Test failed.  See above for more details.

我确信很多人都在使用 jest，而我错过了一些愚蠢的东西..有什么想法可以解决这个问题吗？

Answer 1

尝试在 package.json 的 jest 配置中禁用 React 模拟:

"unmockedModulePathPatterns": [
  "<rootDir>/node_modules/react",
  "<rootDir>/node_modules/fbjs"
]
