这是我的mocha测试文件 test-api.js :

var should = require('should');
var mongoose = require('mongoose');
var request = require('supertest');
var db = require('../config/db');
var post = require('../app/models/post');
var faker = require('faker');


describe('Post', function () {
    var url = 'http://localhost:3000';

    before(function (done) {
        var db_url = db.url_test;
        mongoose.connect(db_url, done);
    });

    it('should post a post and get the post back', function (done) {
        var _body = {
            title: faker.name.title(),
            body: faker.lorem.paragraph()
        };
        //console.log(_body);
        request(url)
            .post('/api/post')
            .send(_body)
            .end(function (err, res) {
                //if (err) {
                //    console.log(err);
                //    //console.log('/api/post post method failed!');
                //}
                //console.log('res.body: ');
                //console.log(res.body);
                res.body.should.have.property('url');
                res.body.should.have.property('title');
                res.body.should.have.property('body');
                res.body.should.have.property('date');
                done();
            });
    });

    it('should get all the posts', function (done) {
        request(url)
            .get('/api/post')
            .expect(200)
            .end(function (err, res) {
                if (err) {
                    console.log(err);
                    //console.log('/api/post get method failed!')
                }
                res.body.should.have.property('count');
                res.body.should.have.property('limit');
                res.body.should.have.property('page');
                res.body.should.have.property('results');
                //console.log(res.body);
                done();
            });
    });
});

我觉得问题出在before函数里面，因为如果我把mongoose.connect()放在server.js里面 (这是我的api服务器的启动文件), 我就可以正常通过测试.

但是我想在测试文件中临时指定单独的测试用数据库，而不是在server.js里面就指定好，所以把mongoose.connect()放在测试文件内.

这是上面这个mocha测试文件的测试结果:

  Post
    1) should post a post and get the post back
    ✓ should get all the posts (52ms)


  1 passing (2s)
  1 failing

  1) Post should post a post and get the post back:
     Error: timeout of 2000ms exceeded. Ensure the done() callback is being called in this test.

我现在也不知道要怎么处理这个问题了，求各位大神帮忙啊！(T_T)...先谢谢大家了！

describe('#get_all_unchecked()', function() { it('should return get_all_unchecked().length() > 0 when only 1 product', function(done) { this.timeout(15000); Product.get_all_uncheckedAsync().then(function(products){ var product = products[0] //console.log("spread" + product.name); assert.equal(product.name, 'get all'); done() }).catch(function(err) { console.log("There was an error" + err); done(err) }); }); ```
