开玩笑的问题-ReactElement.js:无法获取模拟元数据 [英] Jest issue - ReactElement.js: Failed to get mock metadata

问题描述

我有一个非常简单的测试

I've a very simple test

/** @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. 添加任何node_module引用的那一刻，我开始看到以下错误

Test works fine as long as I dont require TestUtils. The moment I add any node_module reference, I start seeing below error

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

● Runtime Error

Error: ../stores/__tests__/simple-test.js:

我确定很多人都在开玩笑，我想念一些愚蠢的东西..想出任何办法解决这个问题吗?

I'm sure a lot of people are using jest and I'm missing something silly..appreaciate any ideas to fix this issue?

推荐答案

尝试禁用对响应的模拟-在package.json的jset配置中:

Try to disable mocking for react - in your jset configuraction in package.json:

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