如何使用Jasmine执行nodeJS集成测试?

我找到了一个简单的方法来使用 beforeEach 开始 express 在套房前。

jasmine 2.6.0 和 express 4.15.3

最小示例:

//server.js 
const express = require('express')
const app = express()

app.get('/world', function (req, res) {
  res.send('Hello World!')
})

app.get('/moon', function (req, res) {
  res.send('Hello Moon!')
})

app.listen(3000, function () {
  console.log('Example app listening on port 3000!')
})



//spec/HelloSpec.js
var request = require("request");

describe("GET /world", function() {
  beforeEach(function() {
    //we start express app here
    require("../server.js");
  });


  //note 'done' callback, needed as request is asynchronous
  it("returns Hello World!", function(done) {
    request("http://localhost:3000/world", function(error, response, html){
      expect(html).toBe("Hello World!");
      done();
    });
  });

  it("returns 404", function(done) {
    request("http://localhost:3000/mars", function(error, response, html){
      expect(response.statusCode).toBe(404);
      done();
    });
  });

});

jasmine 命令返回预期的:

Started
Example app listening on port 3000!
..


2 specs, 0 failures
Finished in 0.129 seconds

服务器关闭(端口3000也关闭)

我希望这有帮助。
