Jasmine : Expect $http.post() not have been called

Question

In an angularjs program I'd like to test with Jasmine if an http post is NOT performed in a test.

I've try the following code :

expect($http.post).not().toHaveBeenCalled();

But I get "ReferenceError: $http is not defined"

Solution 1

That is error is because you never injected $http into the test. You can do this with the inject function, but for testing $http calls, you really should use $httpBackend

For requests that you want to make sure they aren't called, you don't need to do anything. Angular throws an error when it gets a request that wasn't expected (as defined by the expect functions on $httpBackend). So If a request is made that shouldn't be, the tests will fail from this error thrown from an unexpected request.

Solution 2

This is old but I used the following to test for this.

expect($httpBackend.flush).toThrowError('No pending request to flush !');

Ok, in other tests I test if $http.post is called with scope.httpBackend.expectPOST('MY_ENDPOINT', data) which works. Now in a test I want to test that a post request is not made. I don't see any post method in $httpBackend to do kind of test : expect(scope.httpBackend.post).not.toHaveBeenCalled(); Note that in beforeEach i've inject $httpBackend in my scope : scope.httpBackend = $httpBackend;

This is not entirely true. If you don't call $httpBackend.flush(), you will not get an unexpected request error. If you do call $httpBackend.flush() and the request is not made, you will get a No pending request to flush error. There must be a better way.
