node.js - 使用 SailsJS 和 Superagent 运行 Mocha 测试

Question

我目前正在使用 SailsJS 编写应用程序。到目前为止所做的工作在“手动”测试时按预期工作，但在使用 Mocha 测试时却没有。

我试着关注 SailsJS testing guide ，用 npm 调用测试:

[...]
"scripts": {
  "start": "node app.js",
  "debug": "node debug app.js",
  "test": "mocha test/bootstrap.test.js test/unit/**/*.test.js"
},
[...]

我的测试目录结构如下:

test
├── bootstrap.test.js
├── mocha.opts
└── unit
    └── controllers
        └── UserController.test.js

boostrap.test.js:

var Sails = require('sails');
var sails;

before(function(done) {
  Sails.lift(function(err, server) {
    sails = server;
    if (err) return done(err);
    done(err, sails);
  });
});

after(function(done) {
  Sails.lower(done);
});

UserController.test.js:

var request = require('supertest');

describe('UsersController', function() {

  describe('#logout()', function() {
    it('should respond with a 401 status because nobody is logged in', function (done) {
      request(sails.hooks.http.app)
        .put('/user/logout')
        .expect(401, done)
    });
  });

  describe('#signup()', function() {
    it('should create and log in an user', function (done) {
      request(sails.hooks.http.app)
        .post('/user')
        .send({
          firstname: 'foo',
          name: 'bar',
          email: 'foo@bar.com',
          sex: true,
          password: 'foobar',
          birthdate: '01/01/1991',
          phoneNumber: '+33 3 10 10 10'
        })
        .expect(200, done)
    });
  });

  describe('#logout()', function() {
    it('should log out an user', function (done) {
      request(sails.hooks.http.app)
        .put('/user/logout')
        .expect(200, done)
    });
  });

  describe('#login()', function() {
    it('should respond with a 404 status because credentials are invalid', function (done) {
      request(sails.hooks.http.app)
        .put('/user/login')
        .send({
          email: 'bar@foo.com',
          password: 'barfoo'
        })
        .expect(404, done)
    });
  });

  describe('#login()', function() {
    it('should log in an user', function (done) {
      request(sails.hooks.http.app)
        .put('/user/login')
        .send({
          email: 'foo@bar.com',
          password: 'foobar'
        })
        .expect(200, done);
    });
  });

  describe('#login()', function() {
    it('should respond with a 401 status because user is already logged in', function (done) {
      request(sails.hooks.http.app)
        .put('/user/login')
        .send({
          email: 'foo@bar.com',
          password: 'foobar'
        })
        .expect(401, done);
    });
  });
});

最后，这是我调用 npm test 时的输出:

> sails@0.0.0 test /Users/fwoelffel/Dev/STOFMA
> mocha test/bootstrap.test.js test/unit/**/*.test.js



  UsersController
    #logout()

      2) should respond with a 401 status because user is already logged in


  4 passing (1s)
  2 failing

  1) UsersController #logout() should log out an user:
     Error: expected 200 "OK", got 401 "Unauthorized"
      at net.js:1419:10

  2) UsersController #login() should respond with a 401 status because user is already logged in:
     Error: expected 401 "Unauthorized", got 200 "OK"
      at net.js:1419:10



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

总而言之，我正在测试 auth/unauth API。以下是政策:

• 当登录用户尝试登录时，“未经身份验证”策略应抛出错误 (401)
• 当登录用户尝试注册时，“未经身份验证”策略应抛出错误 (401)
• 当已注销的用户尝试注销时，“已验证”策略应抛出错误 (401)

我可能做错了什么，但我真的不知道是什么。你能帮忙解决这个问题吗？

如果您需要更多信息，请询问。您可能会找到代码(没有测试，因为它们失败了)on Github .

感谢阅读，祝你有美好的一天!

更新

感谢 elsaar，我将代码更改为:

var request = require('supertest');
var agent;

describe('UsersController', function() {

  before(function(done) {
    agent = request.agent(sails.hooks.http.app);
    done();
  })

  describe('#logout()', function() {
    it('should respond with a 401 status because nobody is logged in', function (done) {
      agent
        .put('/user/logout')
        .expect(401, done)
    });
  });

  describe('#signup()', function() {
    it('should create and log in an user', function (done) {
      agent
        .post('/user')
        .send({
          firstname: 'foo',
          name: 'bar',
          email: 'foo@bar.com',
          sex: true,
          password: 'foobar',
          birthdate: '01/01/1991',
          phoneNumber: '+33 3 10 10 10'
        })
        .expect(200, done)
    });
  });

  describe('#logout()', function() {
    it('should log out an user', function (done) {
      agent
        .put('/user/logout')
        .expect(200, done)
    });
  });

  describe('#login()', function() {
    it('should respond with a 404 status because credentials are invalid', function (done) {
      agent
        .put('/user/login')
        .send({
          email: 'bar@foo.com',
          password: 'barfoo'
        })
        .expect(404, done)
    });
  });

  describe('#login()', function() {
    it('should log in an user', function (done) {
      agent
        .put('/user/login')
        .send({

        })
        .expect(200, done);
    });
  });

  describe('#login()', function() {
    it('should respond with a 401 status because user is already logged in', function (done) {
      agent
        .put('/user/login')
        .send({
          email: 'foo@bar.com',
          password: 'foobar'
        })
        .expect(401, done);
    });
  });
});

Answer 1

我认为 session 没有被持久化，所以你在之前的请求中登录的用户不会在以后的请求中登录。单元测试应该是这样的。因此，在运行测试之前，您必须确保用户处于所需的状态(登录或注销)。

编辑 - 您需要使用相同的 super 测试代理实例来保持您的 session - https://github.com/visionmedia/supertest/issues/46#issuecomment-58534736

所以只需在测试开始时执行此操作，并在所有测试中使用相同的代理

var supertest = require('supertest');
    agent = supertest.agent(sails.hooks.http.app);

// the use the agent to test your endpoints
