Overview of this book

Python is the language of choice for millions of developers worldwide that builds great web services in RESTful architecture. This second edition of Hands-On RESTful Python Web Services will cover the best tools you can use to build engaging web services. This book shows you how to develop RESTful APIs using the most popular Python frameworks and all the necessary stacks with Python, combined with related libraries and tools. You’ll learn to incorporate all new features of Python 3.7, Flask 1.0.2, Django 2.1, Tornado 5.1, and also a new framework, Pyramid. As you advance through the chapters, you will get to grips with each of these frameworks to build various web services, and be shown use cases and best practices covering when to use a particular framework. You’ll then successfully develop RESTful APIs with all frameworks and understand how each framework processes HTTP requests and routes URLs. You’ll also discover best practices for validation, serialization, and deserialization. In the concluding chapters, you will take advantage of specific features available in certain frameworks such as integrated ORMs, built-in authorization and authentication, and work with asynchronous code. At the end of each framework, you will write tests for RESTful APIs and improve code coverage. By the end of the book, you will have gained a deep understanding of the stacks needed to build RESTful web services.

Improving testing coverage


Now, we will write additional unit tests to improve the testing coverage. Specifically, we will write unit tests related to the hexacopter motor and the altimeter.

 

Open the tests.py file in the root folder for the virtual environment (Tornado01). Insert the following lines after the last line. The code file for the sample is included in the restful_python_2_11_02 folder, in the Django01/tests.py file:

async def 
test_set_and_get_hexacopter_motor_speed(http_server_client): 
    """ 
    Ensure we can set and get the hexacopter's motor speed 
    """ 
    patch_args = {'motor_speed_in_rpm': 200} 
    patch_response = await http_server_client.fetch( 
        '/hexacopters/1',  
        method='PATCH',  
        body=json.dumps(patch_args)) 
    assert patch_response.code == HTTPStatus.OK 
    get_response = await http_server_client.fetch( 
        '/hexacopters/1', 
        method='GET') 
    assert get_response.code == HTTPStatus.OK 
    get_response_data = escape...
