使用SailsJS和Superagent運行摩卡測試

Question

我目前正在使用SailsJS編寫應用程序。到目前爲止所做的工作都是按照預期進行的，而不是在用摩卡進行測試時。

我試圖按照SailsJS testing guide，調用帶有NPM測試：

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

我的測試目錄結構如下：

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); 
    }); 
    }); 
}); 

最後，這裏是我的輸出，當我打電話NPM測試：

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

     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. 

總結的東西了，我測試一個auth/UNAUTH API。下面一個是政策：

• 當登錄的用戶試圖登錄時，「未經驗證的」政策應該拋出一個錯誤（401）
• 當登錄的用戶嘗試註冊時，「未認證「政策應該拋出一個錯誤（401）
• 當註銷用戶嘗試登錄時，將‘證實’的政策應該拋出一個錯誤（401）

我可能做錯了什麼，但我真的不知道它是什麼。你能幫助解決這個問題嗎？

如果您需要更多信息，請詢問。你可能會發現代碼（沒有測試，因爲它們失敗）on Github。

感謝您的閱讀，祝您有個愉快的一天！

UPDATE

感謝elsaar，我改變了我的代碼：

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({ 
      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) { 
     agent 
     .put('/user/login') 
     .send({ 
      email: 'foo@bar.com', 
      password: 'foobar' 
     }) 
     .expect(401, done); 
    }); 
    }); 
});

我認爲會議沒有被堅持着，所以用戶已在前面的請求的loggedIn不會在稍後的請求中進行登錄。單元測試應該是這樣的。因此，在測試運行之前，您必須確保用戶處於期望的狀態（登錄或退出）。

編輯 - 你需要使用supertest代理的同一實例，以保存會話 - https://github.com/visionmedia/supertest/issues/46#issuecomment-58534736

因此，只要做到這一點，在你的測試開始，並使用相同的代理在所有測試中

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

// the use the agent to test your endpoints
