摩卡测试：Test.serverAddress上的“ TypeError：未定义不是函数”

Question

I have the following test:

describe('Testing the GET methods', function() {
    it('Should be able to get the list of articles', function(done) {
      // Create a SuperTest request
      request(app).get('/api/articles/')
          .set('Accept', 'application/json')
          .expect('Content-Type', /json/)
          .expect(200)
          .end(function(err, res) {
              res.body.should.be.an.Array.and.have.lengthOf(1);
              res.body[0].should.have.property('title', article.title);
              res.body[0].should.have.property('content', article.content);

              done();
      });
    });

    it('Should be able to get the specific article', function(done) {
      // Create a SuperTest request
      request(app).get('/api/articles/' + article.id)
          .set('Accept', 'application/json')
          .expect('Content-Type', /json/)
          .expect(200)
          .end(function(err, res) {
              res.body.should.be.an.Object.and.have.property('title', article.title);
              res.body.should.have.property('content', article.content);

              done();
      });
    });
  });

Which produces this following error:

any ideas what might be the issue? I have all dependencies checked and installed and required.

EDIT:

The reason this happens is this: https://github.com/Oreqizer/mean-book/blob/master/server.js - lines 11 to 18.

My tests start BEFORE the app connects to the db. I noticed this by console.logging 'app', as well as noticing that Server running at http://localhost:3000/ gets logged at different times during the first test.

How do I make mocha wait for the app to be defined before running the tests?

Answer 1

OK so it goes like this:

newer version of 'mongoose' causes express not to have a defined 'db' connection before i do var app = express(db); . However, if I add the code that goes:

db.connection.on('connected', callback);

where in the callback I define app , the test gets executed without app being defined.

I really don't know how to fix this besides having two different versions, one for test environment and one for development/production.
