AngularJS Jasmine Unit Tests

Solution
A little-known tip about testing/mocking async requests with jasmine and AngularJS:
If you're not explicitly calling the request in your test (i.e. calling it through another function), the request won't be digested by Angular, so it makes it seem as if the request never fired (when you call `flush()`)
Try running `scope.$digest()` before your `httpBackend.flush()` call, that may do the trick. See this thread for more information.
Problem
I have the following unit tests, and for some reason the second test makes other tests fail. ``` beforeEach(inject(function ($rootScope, _$httpBackend_, $controller, $location, mockedResource) { scope = $rootScope.$new(); httpBackend = _$httpBackend_; locationService = $location; ctrlDependencies = { $scope: scope, resource: mockedResource, } var ctrl = $controller('myController', ctrlDependencies); })); it('should redirect to a new page', function() { scope.pageRedirectFunction(); expect(locationService.path()).toBe('/newpage') }); it('should delete an epic resource', function() { httpBackend.expectGET('/api/v1/epic/1').respond({}); httpBackend.expectDELETE('/api/v1/epic/1').respond({}); // Run the deletion function scope.deleteEpicResource() httpBackend.flush() // This line seems to be the rebelious one expect(scope.epicResources.length).toEqual(0) }) ``` I have managed to figure out the line that seems to cause the errors, and it's the `httpBackend.flush()` line. Why is the flush function causing strange behaviour? The actual error I get from running the command `karma start` in the terminal, is: ``` Delaying execution, these browsers are not ready: Chrome 29.0 .... ``` after a little while, the Chrome session then crashes.
