摩卡显示整个单元测试失败

Question

我正在使用Express js在Node js中进行单元测试，并且为了测试我正在使用mocha和模拟我使用sinon的数据。一切都很好，但我的问题是，当我运行测试用例如果it()包含多个断言，其中任何人都失败了，那么摩卡显示整个it()失败。但是我希望其他断言即使失败也能通过。 我不想为每个字段写一个它（）。我的测试代码

//loading testing dependencies 
var request = require('supertest'); 
var server = require('./app'); 
var chai = require('chai'); 
var chaiHttp = require('chai-http'); 
var sinon = require("sinon"); 
var should = chai.should(); 

//configuring chai 
chai.use(chaiHttp); 

//ORM controller (we need to mock data in it's method) 
var rootController = require('./app/controllers/users/users_controller'); 

//Writing test cases 
describe('loading express', function() { 
    //mock data before each request 
    before(function(){ 
     //select the method of the ORM controller which you want to mock 
     sinon.stub(rootController, "get", //get is the method of ORM's customers_controller' 
     function(req, res, next){ 
     //response object which we are going to mock 
      var response = {}; 
      response.status = 'success', 
      response.data = { 
      userId: '0987654321@ef', 
      userName:'John' 
      }; 
      next(response); 
     }); 
    }); 
    it('responds to /users/getUserData', function testMethod(done) { 
    //call server file (app.js) 
    request(server) 
     //send request to the Express route which you want to test 
     .get('/users/getUserData?id=0987654321') 
     //write all expactions here 
     .expect(200) 
     .end(function(err, res){ 
     console.log("Generated response is ", res.body); 
     res.should.have.status(200); 
     res.body.should.be.a('object'); 
     //res.body.status.should.equal("success"); 
     res.body.data.userId.should.equal("0987654321@ef347389"); 
     res.body.data.userName.should.equal("John"); 
     //done is the callback of mocha framework 
     done(); 
     }); 

    }); 

    it('responds to /', function testSlash(done) { 
    request(server) 
     .get('/') 
     .expect(200, done); 
    }); 

    it('404 everything else', function testPath(done) { 
    request(server) 
     .get('/foo/bar') 
     .expect(404, done) 

    }); 

}); 

您可以在这里看到我的用户id应该失败和用户名应传递，但是当我运行这段代码它说，响应/用户/ getCustomerData得到了失败。而不是它摩卡应该说，userId字段失败，并且userName字段已通过。

这不是摩卡和should的工作方式：当断言失败时，should会引发错误，这意味着代码的其余部分（包括任何后续的断言）将不会执行。

你可以重写你的测试，使该申请只进行一次，但每个断言仍是单独进行测试：

describe('responds to /users/getUserData', function testMethod(done) { 
    let reqErr, reqRes; 

    before(function(done) { 
    request(server) 
     .get('/users/getUserData?id=0987654321') 
     .expect(200) 
     .end(function(err, res) { 
     reqErr = err; 
     reqRes = res; 
     done(); 
     }); 
    }); 

    it('should have the correct body type', function() { 
    reqRes.body.should.be.a('object'); 
    }); 

    it('should have the correct userId', function() { 
    reqRes.body.data.userId.should.equal("0987654321@ef347389"); 
    }); 

    it('should have the correct userName', function() { 
    reqRes.body.data.userName.should.equal("John"); 
    }); 

});
