当摩卡testing失败时，它将一个对象logging到控制台
当我所有的testing通过，一切都按预期工作。 然而，当一个testing失败并且任何记者处于活跃状态时，赛跑者都会打印出一个代表追踪痕迹的对象，而不是我在屏幕截图中看到的格式不正确的错误消息

describe('GET /sites', function (){ var url = 'http://localhost:' + app.get('api').port + '/sites'; it('should return a 200 OK', function (done){ request(url, function (err, res){ res.should.have.status(200); done(); }); }); it('should be a JSON response', function (done){ request(url, function (err, res, body){ res.should.be.json; done(); }) }); it('should be an array', function (done){ request(url, function (err, res, body){ JSON.parse(body).should.not.be.an.instanceOf(Array); done(); }); }); });
任何线索，为什么我没有得到美丽的景色？
该对象由于asynchronous行为而被logging到控制台。 should.js正确抛出错误，但不作为done()callback的参数。 我通过在try / catch语句中包装来修复，所以我可以将错误传递给done() 。
it('should return a 200 OK', function (done){ request(url, function (err, res){ try { res.should.have.status(200); } catch (e){ done(e); } }); });
您使用--ignore-leaks表明您使用的是过时的摩卡版本。 （这是因为改为--check-leaks 。）
使用npm install -g mocha安装最新版本。
另外，你似乎正在得到JSON记者。 检查你是否有一个test/mocha.opts文件，但我不明白为什么它不会被你的命令行参数覆盖。
