Exploring the topic of AngularJS unit testing and working with httpBackend timeouts

I have experience in the testing world, particularly with TDD using tools like mocha, sinon, chai, and nodejs.

Recently, I've been finding AngularJS testing a bit challenging to grasp and implement.

Currently, I am trying to test the simplest method possible, as shown below:

/** @test {HateoasService#loadResource}*/
describe('HateoasService', function() {

  let service = null;
  let remoteBackend = null;
  beforeEach(angular.mock.module('app'));

  beforeEach(inject((HateoasService, $httpBackend) => {
    remoteBackend = $httpBackend;
    service = HateoasService;
  }));

  afterEach(function() {
    remoteBackend.verifyNoOutstandingExpectation();
    remoteBackend.verifyNoOutstandingRequest();
  });

  it('should resolve a promise with status 200', () => {

    remoteBackend.when('GET', 'http://google.fr')
      .respond(200, {});

    service.loadResource('http://google.fr').then((res) => {
      expect(res.status).toEqual(200);
      remoteBackend.flush();
    });
  });

});

This code snippet corresponds to the following method:

loadResource(resource) {
    return this.http.get(resource);
  }

However, I seem to be encountering issues with httBackend flushing and receiving an error: Error: Unflushed requests: 1.

Could you provide assistance in getting this test to work correctly?

Answer №1

The callback function provided as the second argument to the it method in Mocha must include a parameter indicating that it is asynchronous. Make sure to call the callback function after performing any necessary operations.

it('should resolve a promise with status code 200', done => {

remoteBackend.when('GET', 'http://google.com')
  .respond(200, {});

service.loadResource('http://google.com').then((res) => {
  expect(res.status).toEqual(200);
  remoteBackend.flush();
  done();
});

});
