How write unit test for receiving nsnotification asynchronous?

I call rest web servic with completion handler and if succeed I send NSNotification.

The problem is how to write unit test to assert that the notification is sent in case of success.

Any help will be appreciated.


  • You can add an expectation for the notification:

    expectationForNotification("BlaBlaNotification", object: nil) { (notification) -> Bool in
    // call the method that fetches the data
    waitForExpectationsWithTimeout(5, handler: nil)

    But personally I would split this is two tests. One for the fetching of the data (tested using a stub) and one for the sending of the notification.
