Jest

请记住: 最难写的单元测试是第一个单元测试

第一个单元测试

1. npm install --save-dev jest

2. 例如我有一个方法,校验url是否为正规的url,我的测试代码

    import common from '../../Public/Common/Common'
    const TEST_URL = {
        'common': 'http://xunlei.com?name=404&author=mzk#ahaha'
    }
   
    test('get_url_info',() => {
        var url_info = common.get_url_info( TEST_URL.common );
        expect(url_info.is_url).toBe(true);
    })
   

3. 在package.json里添加

      "scripts": {
        "test": "jest"
      },
   

4. npm test

     ~/Learning/apache_sites/K-Utils: npm run test
   
    > [email protected] test /Users/maizhikun/Learning/apache_sites/K-Utils
    > jest
   
     PASS  Test/Common/Common.test.js
