如何在控制器中测试角度$ destroy

Question

我有控制器监听destroy事件,我无法弄清楚如何测试这个事件.

有谁知道怎么测试毁灭？

在控制器中:

$scope.$on('$destroy', function () {
    //does something
});

在测试中:

beforeEach(inject(function ($rootScope, $injector) {
    rootScope = $injector.get('$rootScope');
    scope = $rootScope;
}));

it('should do something when scope $destroyed', function () {
    //how to trigger the destroy event listened for in controller?
    expect(somefunction).toHaveBeenCalled();
});

谢谢

我没有尝试过,但范围有一个功能$destroy().在执行断言之前调用它.

it('should do something when scope $destroyed', function () {
    //how to trigger the destroy event listened for in controller?
    scope.$destroy();  // created somewhere before each test
    expect(somefunction).toHaveBeenCalled();
});
