API testing involves testing the application programming interfaces (APIs) directly and as part of integration testing to determine if they meet expectations for functionality, reliability, performance, and security. Since APIs lack a GUI, API testing is performed at the message layer. API testing is critical for automating testing because APIs now serve as the primary interface to application logic and because GUI tests are difficult to maintain with the short release cycles and frequent changes commonly used with Agile software development and DevOps.

In this blog we will demonstrate how you can design an automation framework for API testing using python.

Pre-requisites
Working knowledge about Python scripting
Working knowledge of API under test
PyCharm IDE
PyTest
Setting up project
First, we will need to create a new Python project with PyCharm. If you are already aware about how to create Python Project with PyCharm, please move to the next section. Or you can refer to this guide about how to setup your first Python project with PyCharm :
https://www.jetbrains.com/help/pycharm/creating-and-running-your-first-python-project.html

Writing ...
... test case
As now you already have setup your python project with Pycharm, let’s create a new python file where we will add our test cases.

Please create a new python file in your project. Let’s name it “test_apitest.py”. Notice the “test_” in your file name. This is as per the rules for PyTest. We will be running our tests using Python’s inbuilt testing framework called PyTest. PyTest picks all those python files in your project which start with “test_” for test execution.

In “test_apitest.py” file, our first statement would be :

import requests
“requests” is python’s inbuilt module which is used to send http requests to a server. We will be using this module to send requests to our API and record the response.

Now, for this tutorial we will be using a sample test API available online : https://reqres.in/api
We will be sending requests to the endpoints defined in this API.
