當摩卡測試失敗時，它將一個對象記錄到控制檯

當我所有的測試通過時，一切都按預期工作。然而，當測試失敗，任何記者活躍，亞軍打印代表STRACK跟蹤，而不是漂亮的格式錯誤消息我在屏幕截圖當摩卡測試失敗時，它將一個對象記錄到控制檯

這裏看到一個物體是測試

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(); 
    }); 
    }); 

});

任何線索，爲什麼我沒有得到美麗的景色？

您使用--ignore-leaks表明您使用的是過時的摩卡版本。（因爲變更爲--check-leaks。）

安裝最新版本npm install -g mocha。

此外，你似乎得到了JSON記者。檢查你是否有test/mocha.opts文件，但我不明白爲什麼它不會被你的命令行參數覆蓋。

感謝您的回答，但不幸的是不是解決方案。沒有摩卡選擇，因爲我更喜歡在make文件中使用內聯命令。 – srquinn 2013-04-21 12:05:44

由於異步行爲，對象被記錄到控制檯。 should.js正確拋出錯誤，但不作爲done()回調的參數。我通過在try/catch語句中包裝來修復，所以我可以將錯誤傳遞給done()。

it('should return a 200 OK', function (done){ 
    request(url, function (err, res){ 
    try { 
     res.should.have.status(200); 
    } 
    catch (e){ 
     done(e); 
    } 
    }); 
});
