AngularJS / Typescript/ AMD / RequireJS / Jasmine / Karma / Sinon

我有一个 AngularJS 自定义日志服务，它构建了一个私有的内部日志消息队列。此内部队列仅计算其队列中非调试类型的消息。在某些时候，它会将这个私有队列发送到 API（由消息大小限制和前面提到的计数处理）。这个逻辑也是私有的。我需要捕获该 http.POST 并检查传递给它的对象，以确保在包含所有消息的对象中未发送任何调试。

这是单元测试，所以我可以访问 httpBackEnd，但我不知道如何获取参数。我也有 jasmine spy，甚至是 sinon，但到目前为止我尝试过的方法都没有产生结果。

module MyLogClass {
  export class Logger implements ng.ILogService {
     private _currentSize: number = 0;
     private _currentBatch: myLoggingType[] = new Array<myLoggingType>();
     public totalNumberOfMessages: number = 0;
     public includeDebug: boolean = false;         
     .
     .
     .
     //Overriding all the Angular log functions (public functions)
     //Logic for striping out debug messages if needed (private functions)
     //Logic for handling when to send in here (private functions)
     private SendLogs = () => {
          this.http.post('someurl', (this._currentBatch))
            .success( (data: any[], status, headers, config) => {
               console.log('logs sent');
            })
            .error( (data: any[], status, headers, config) => {
               //error handling call
            });
     }
  }
}

这是一个简短的介绍，描述了我的日志替代 Angulars 的要点。这是我试图通过单元测试实现的一些示例代码。

beforeEach(angular.mock.inject(function ($http: ng.IHttpService, $httpBackend: ng.IHttpBackendService) {                    
        localService = new MyLogService();
        localService.LogHttp = $http; 
        httpBackend = $httpBackend;            
    }));
 it('should strip Debug messages, then send messages and reset size', () => {
        localService.totalNumberOfMessages = 50;

        // Fill the Queue, make sure to put in some debug messages.
        var i = 0;
        // Right here I need to figure out how to catch the data sent to that URL 
        // The code I'm showing here is for example, I don't know what this expectPOST should look like.  
        httpBackend.expectPOST('someurl', data).respond('passed');
        while (i < 50) {
            // generating fake calls to the log service
            i++;
        }

        httpBackend.flush();
        // Check the data sent to make sure there were no debug messages in it.  Only how?
