When using AngularJS in conjunction with Karma-Jasmine, it is important to note that the functions verifyNoOutstandingExpectation() and verifyNoOutstandingRequest() may not

There is an unresolved HTTP request that needs to be flushed. When I use the following code

afterEach(function(){
      $httpBackend.verifyNoOutstandingExpectation();
      $httpBackend.verifyNoOutstandingRequest();
});

The code functions correctly and I receive the error message

Error: Unflushed requests: 1

The error is triggered by the 

$httpBackend.verifyNoOutstandingRequest();
line. However, if I use the code below instead

afterEach(function(){
    $httpBackend.verifyNoOutstandingRequest();
});

No error is generated.

This raises the question of why this behavior occurs. Do both methods need to always be used together?

Answer №1

The AngularJS documentation contains the following information:

verifyNoOutstandingExpectation();

This function verifies that all requests defined through the expect API have been made. If any requests were not made, an exception is thrown by verifyNoOutstandingExpectation.

It is possible that you are receiving an exception because you have not defined any expect calls but are using verifyNoOutstandingExpectation.
