服务上的这个模块声明用于测试，但不用于AngularJS上的其他东西，这是什么？,angularjs,karma-jasmine,Angularjs,Karma Jasmine,我正在开发一个相当复杂的angularjs应用程序。我有一个服务，我想通过karma+jasmin来测试；但如果它在测试中运行良好，则会导致应用程序崩溃，反之亦然（如果应用程序正常运行，则测试失败） 唯一更改的行是服务声明中的这一行： var app = angular.module('inspinia', []); //test works - app crashes var app = angular.module('inspinia'); //app works, test crashes

我正在开发一个相当复杂的angularjs应用程序。我有一个服务，我想通过karma+jasmin来测试；但如果它在测试中运行良好，则会导致应用程序崩溃，反之亦然（如果应用程序正常运行，则测试失败）

唯一更改的行是服务声明中的这一行：

var app = angular.module('inspinia', []); //test works - app crashes
var app = angular.module('inspinia'); //app works, test crashes
测试失败时出错：

这是我的服务的高度简化版本（但足以重现错误）：

这是我的单元测试（也是简化的）：

所以我有两个问题： 1.我的模块声明之间有什么区别
2.我该怎么做才能让我的测试和应用程序正常工作？

这可能是你简化的一部分，但是app.factory（'PrService'）应该是app.factory（'ProductService'）吗？还有，angular的版本是什么？对不起，在写问题的时候是打字错误。不，我使用的是产品服务（编辑了问题）。产品服务上没有GetAll方法。错误缺少堆栈跟踪，这可能有助于检测问题，“ProductService可以获取我的工厂失败的实例”是不够的。谢谢，我删除了这一行，因为它与示例无关，我还将堆栈跟踪添加到问题中。仍然不清楚它失败的确切原因，规范输出中没有异常。但是
angular.module（'inspinia'）
意味着模块已经在其他地方定义了
angular.module（'inspinia'，[]）
