[英]angularjs: how to mock $rootScope in unit test
我有一个看起来像这样的单元测试
describe('Interceptor: myInterceptor', inject(function($rootScope){
var rootScope, routeParams = { id: null };
beforeEach(module('MyApp', function ($provide) {
$provide.factory('$routeParams', function () { // mock $routeParams
return routeParams;
});
rootScope = $rootScope.$new();
$provide.value('$rootScope', rootScope); // mock $rootScope
}));
....
}));
但是,当我如上所述执行“ inject(function($ rootScope){..”)时,出现以下错误(使用Karma和PhantomJS):
PhantomJS 1.9.2 (Mac OS X) Interceptor: myInterceptor encountered a declaration exception FAILED
TypeError: 'null' is not an object (evaluating 'currentSpec.$modules')
at workFn (/dev/myapp/app/bower_components/angular-mocks/angular-mocks.js:2072)
at /dev/myapp/test/spec/interceptors/my-interceptor.js:67
....
我认为在调用describe
时注入不起作用。 我遇到了相同的错误,可以通过将注入从我的describe
调用移到beforeEach
调用来解决:
var rootScope;
beforeEach(inject(function ($rootScope) {
rootScope = $rootScope.$new();
}));
您可以有多个beforeEach
,因此只需在现有的beforeEach
之上添加一个。
