angular.mock.module 和 angular.mock.inject 函数在 jasmine 的 beforeAll 中不起作用

Question

I want to use jasmine's beforeAll instead of beforeEach but angular.mock.module and angular.mock.inject functions are not working in beforeAll whereas they're working in beforeEach.

Here is my test. the same code is working in beforeEach approach.

describe("This is a test", function () {
    beforeAll(module("app"));

    var vm;
    beforeAll(function() {
        angular.mock.module(function ($provide) {
            $provide.factory("dataService", ["$q", function ($q) {
                return {
                    getSomeDataById: function () { return $q.resolve({ }); }
                };
            }]);
        });

        angular.mock.inject(function (_$controller_,dataService) {
            vm = _$controller_("TestController",
            {
                dataService: dataService
            });
        });
    });
});

I was facing a similar problem and using the module.sharedInjector() call resolved it for me:

describe("This is a test", function () {

    // Call SharedInjector before any call that might invoke the injector
    angular.mock.module.sharedInjector();

    beforeAll(module("app"));

    var vm;
    beforeAll(function() {
        angular.mock.module(function ($provide) {
            $provide.factory("dataService", ["$q", function ($q) {
                return {
                   getSomeDataById: function () { return $q.resolve({ }); }
               };
            }]);
        });

        angular.mock.inject(function (_$controller_,dataService) {
            vm = _$controller_("TestController",
            {
                dataService: dataService
            });
        });
    });
});

A quick snippet from the linked docs page to explain why that works (emphasis mine):

[ angular.mock.module.sharedInjector ] ensures a single injector will be used for all tests in a given describe context. This contrasts with the default behaviour where a new injector is created per test case.

Use sharedInjector when you want to take advantage of Jasmine's beforeAll() , or mocha's before() methods. Call module.sharedInjector() before you setup any other hooks that will create (ie call module()) or use (ie call inject()) the injector.
