＆＃39;不再需要预期＆​​＃39;使用$ httpBackend时出错

Question

我正在尝试测试对我的API的简单调用，并且我会绕圈试图弄清楚它为什么会失败。

我已经简化了一些事情。

这将是以下测试的错误：

Error: Unexpected request: GET /api/search?blah=something
No more request expected

以下是测试：

it('does what it should', function() {
  httpBackend.expectGET('/api/search?blah=something').respond(aTestResponse);
  scope.search();
  httpBackend.flush();

  // expectations here...
});

控制器中的搜索功能：

function search() {
  myDataService.getSearchResults().query(mySearchParams, function(response) {
    // do stuff
  }
}

和数据服务功能：

function getSearchResults() {
  return $resource('/api/search', {
    param1: '@param1',
    param2: '@param2',
    ...etc
  });
}

任何建议都会非常感激。

编辑 - 这是我的spec文件的一个经过编辑但更完整的版本：

'use strict';

describe('Controller: BlahCtrl', function() {

  beforeEach(module('blahApp'));

  beforeEach(module(function($urlRouterProvider) {
    $urlRouterProvider.deferIntercept();
  }));

  var BlahCtrl;
  var scope;
  var rootScope;
  var httpBackend;

  beforeEach(inject(function($controller, $rootScope, $httpBackend) {
    httpBackend = $httpBackend;
    scope = $rootScope.$new();
    rootScope = $rootScope;
    BlahCtrl = $controller('BlahCtrl as vm', {
      $scope: scope
    });
    this.testResults = [
      {
        testProperty1: 'test-value-1-1',
        testProperty2: 'test-value-1-2',
        testProperty3: 'test-value-1-3'
      },
      {
        testProperty1: 'test-value-2-1',
        testProperty2: 'test-value-2-2',
        testProperty3: 'test-value-2-3'
      }
    ];
  }));

  beforeEach(function() {
    this.addMatchers({
      toEqualData: function(expected) {
        return angular.equals(this.actual, expected);
      }
    });
  });

  it('stores the search results', function() {
    httpBackend.expectGET('/api/search?blah=something').respond(this.testResults);

    scope.vm.doSearch();
    httpBackend.flush();

    // expectations here...
  });

});
