Can I use $httpbackend.flush(); only when there are pending requests?
This way, I can avoid receiving:
Error: Unflushed requests: 1,2,3,...,n
Or
Error: No pending request to flush!

The documentation mentions using the $http.pendingRequests property to address this issue. Here's a simple example of how you could implement it:
if($http.pendingRequests.length > 0) {
$httpBackend.flush();
}
It may not be the best solution, but it should get the job done.
It is advisable to structure your tests in a way that avoids the use of conditional statements such as "if". This approach helps maintain simplicity and ensures clarity in what is being tested, as using "if" statements can sometimes result in passing a test that should actually fail.
Consider creating separate test functions to handle scenarios where no requests are made to the API.
Familiarize yourself with the AAA (Arrange Act Assert) pattern in testing, as it can be beneficial in guiding your testing process.
In case you are not anticipating any requests, it is recommended to place the call to http.flush(n) inside a try-catch block and ignore the exception if it occurs.
http.whenGet(/* .. */).respond(/*..*/); // Perhaps the implementation requires certain data
service.doSomething();
try { http.flush(99); } // Handling all potential service requests
catch(e) {}
expect(service.isAwesome).toBe(true);
