angularjs - Angular Mocks 'module' 第二次运行失败

Question

我正在尝试为我创建的 angular.service (工厂)编写一些单元测试。我无法让我的测试运行，因为与 angular.mock.inject 函数配对时，angular.mock.module 函数在第二次调用时失败。我已经验证我的测试与这些错误无关，因为它永远不会进入我的第二次测试，并且第一个测试顺利通过。该错误来自 beforeEach ，我在其中重新初始化了正在测试的 Angular 模块。

这是我的简化代码:

// service code
function daEvents ($rootScope) {
  var api = {
    on: function () {}
  };

  return api;
}

daEvents.$inject = ['$rootScope'];

angular.module('test', []).factory('daEvents', daEvents);

// test code
describe('daEvents', function () {
  beforeEach(angular.mock.module('test'));

  var daEvents;
  beforeEach(angular.mock.inject(function (_daEvents_) {
    daEvents = _daEvents_;
  }));

  it('should exist', function () {
    chai.expect(daEvents).to.exist;
  });

  it('should test ok', function () {
    chai.expect(true).to.be.true;
  });
});

我收到此错误:
