There is no pending enable request when used when GET but does not expect GET

Question

There is no pending enable request when used when GET but does not expect GET

When testing the angular service using $ httpBackend, I get unexpected results.

When I run the test using httpBackend.expectGET, the test works as expected. However, if I run the same test using whenGET, the test fails with the message "There is no pending flash request."

Here is the service under test:

.factory('CoverageService', ['$http', function ($http) { return{ GetCoverageReport: function () { return $http.get('../../../js-test-reports/coverage/Chrome 43.0.2357%20(Windows%207)/cobertura-coverage.xml'); },

Here are the tests:

 'use strict'; describe('coverage-manager.js', function () { describe('CoverageService', function () { var httpBackend, sut, rootScope; beforeEach(module('fot')); describe('GetCoverageReport', function () { beforeEach(inject(function ($httpBackend, CoverageService, $rootScope) { httpBackend = $httpBackend; sut = CoverageService; rootScope = $rootScope; })); it('should return data', function () { var expectedData = { testData: 'some data' }; var actualData; httpBackend.expectGET('../../../js-test-reports/coverage/Chrome 43.0.2357%20(Windows%207)/cobertura-coverage.xml').respond(expectedData); sut.GetCoverageReport() .success(function (response) { actualData = response; }); httpBackend.flush(); expect(actualData).toEqual(expectedData); }); it('should return data but says No pending request to flush', function () { var expectedData = { testData: 'some data' }; var actualData; httpBackend.whenGET('../../../js-test-reports/coverage/Chrome 43.0.2357%20(Windows%207)/cobertura-coverage.xml').respond(expectedData); sut.GetCoverageReport() .success(function (response) { actualData = response; }); rootScope.$digest(); httpBackend.flush(); expect(actualData).toEqual(expectedData); }); it('should return data', function () { var expectedData = { testData: 'some data' }; var actualData; httpBackend.whenGET('../../../js-test-reports/coverage/Chrome 43.0.2357%20(Windows%207)/cobertura-coverage.xml').respond(expectedData); sut.GetCoverageReport() .success(function (response) { actualData = response; }); httpBackend.flush(); expect(actualData).toEqual(expectedData); }); }); }); });

The GET is expected to fail when the GET completes with the message “No pending reset request”. I tried using $ rootScope. $ Digest (), as I saw in some posts, was out of luck. Tests are identical except expectGET vs expectWHEN, so not sure what is going on?

And here is the error detail:
