如何使用chai-as-promised測試拒絕承諾和錯誤消息？

Question

我試圖檢查拒絕承諾的錯誤消息，如果我在測試中使消息字符串錯誤，它仍然通過。

MyService.doSomething({ id: 12345 }).should.eventually.be.rejectedWith(TypeError, 'no attr foo defined2'); 



    svc.doSomething = function(thing){ 
    var def = $q.defer(); 

    if (!thing.foo) { 
     def.reject(new Error('no attr foo defined')); 
    } else { 
     def.resolve(thing); 
    } 

    return def.promise; 
    }; 

更新，似乎我的測試工作不正常。當我時間恢復出來：

it.only('should error', function(){ 
    // todo this should fail but it just times out 
    return MyService.doSomething({ id: 12345 }).should.eventually.be.rejectedWith(TypeError, 'no attr foo defined2'); 
    }); 







    svc.doSomething = function(thing){ 
    var def = $q.defer(); 

    if (!thing.foo) { 
     def.reject(new Error('no attr foo defined')); 
    } else { 
     def.resolve(thing); 
    } 

    return def.promise; 
    }; 

這裏的錯誤：

Error: timeout of 4000ms exceeded. Ensure the done() callback is being called in this test.

你就忘記了，最終，您的電話之前，回報！

return MyService.doSomething({ id: 12345 }).should.eventually.be.rejectedWith...
