Improving testing coverage

Now we will write additional tests functions to improve the testing coverage. Specifically, we will write unit tests related to notifications and users.

Open the existing service/tests/test_views.py file and insert the following lines after the last line. The code file for the sample is included in the restful_python_2_04_02 folder, in the Flask01/service/tests/test_views.py file:

def create_notification(client, message, ttl,
notification_category): 
    url = url_for('service.notificationlistresource',  
        _external=True) 
    data = {'message': message, 'ttl': ttl, 'notification_category': notification_category}
