Examining whether an ajax call was not initiated within an Angular application

Is there a way to verify that an ajax request has not been made using Angular's $httpBackend? I attempted to use verifyNoOutstandingRequest() but it doesn't seem to be triggering test failures in version 1.1.5.

Here is more information about the scenario:

In my database module, I am utilizing ngResource to connect to the server-side database. I have configured it so that the GET all operation is cached client-side, meaning only the initial call to my getTable('tableName') method should trigger an ajax request. Therefore, the objective of the test is to confirm that the first call results in an ajax request, while subsequent calls do not.

Answer №1

Ensuring that your test fails when an unexpected request is made is simple – just remember not to define the expect method for it. Angular will automatically generate an error if a request is received that was not anticipated.

For every request, you must include an excpect method in your code. This means creating one expect statement for the initial call to getTable which initiates the request. If any additional requests are made afterwards without an appropriate expect, Angular will trigger an error causing your test to fail.

The structure of your test should resemble the following:

$httpBackend.expectGET("request_url");
getTable("tableName");
$httpBackend.flush();
//No error as the request was expected
getTable("tableName"); //An error will be thrown if an unplanned request is attempted
