Situation: You want to write a spec for a function inside an Angular service. This function at some point makes an API request and acts upon response. Notably, your Angular app employs uiRouter, although it is not used nor actually required for this test.
# Capitalized expressions are intended to be replaced with YOUR values
describe 'SERVICE', ->
beforeEach ->
module 'MODULE'
module ($urlRouterProvider) ->
# Prevent uiRouter's initialization, i.e. do not sync the current URL
# with its routes
$urlRouterProvider.deferIntercept()
inject (_$httpBackend_, _SERVICE_) =>
@$httpBackend = _$httpBackend_
@SERVICE = _SERVICE_
afterEach ->
@$httpBackend.verifyNoOutstandingExpectation()
@$httpBackend.verifyNoOutstandingRequest()
describe 'FUNCTION()', ->
it 'does something', ->
# Maybe some code here
# Call function under test (triggers API request, which will be intercepted)
@SERVICE.FUNCTION()
# ... do something before request is answered
# Set up request expectation
@$httpBackend.expectGET('/api/something').respond
nested:
example: 'json'
# Run all queued requests
@$httpBackend.flush()
# Have a Jasmine expectation
expect(something).toHaveHappened()

$httpBackend
must be injected first for your service to be using it. It will replace the $http
service.
