与Mongoose连接时，Mocha在执行后挂起 [英] Mocha hangs after execution when connecting with Mongoose

问题描述

对话很便宜，请告诉我代码

使用mocha和supertest进行集成测试.这是代码

Doing integration tests with mocha and supertest. Here's the code

//app.js
mongoose.Promise = global.Promise;
mongoose.connect(config.mongoURL, error => {
  if (error) {
    throw error;
  }

  console.log('Connected to mongodb');
});

modules.export = app;



// test.js
it('returns 200', () => {
  return supertest(app).get('/').expect(200);
});

基本上发生的是在测试运行后输出已连接到mongodb"日志(我只喜欢3个测试，没有一个使用db)，然后mocha挂在那里，我必须 Ctrl + C .我可能错过了一些配置，但看不到.

Basically what happens is that the output "Connected to mongodb" logs after the tests are run (I have like 3 tests only, none use the db), and afterwards mocha hangs there and I have to Ctrl+C. I probably missed some configuration but I can't see it.

不用说，注释猫鼬行(mongoose.connect(...))即可解决此问题.

Needless to say, commenting the mongoose lines (mongoose.connect(...)) fixes it.

我想念什么?

推荐答案

测试完成后，您必须与数据库断开连接.例如，可以在after函数中完成此操作.

You have to disconnect from the database after the tests are done. This can be done in the after function, for example.

after((done) => {
  app.close(() => {
    mongoose.connection.close(done);
  });
});

如果不断开连接，您将得到正在描述的症状.

If you don't disconnect you'll get the symptoms you are describing.
