Pytest - API testing with Python requests Pytest is a mature full-featured Python testing frame that helps you write and run tests in Python. First, this tutorial will give an overview of Apiritif, a set of Python utilities for API testing that works with the nose unit test framework. Unit tests is a Python unit testing framework which supports test automation, sharing of setup and shutdown code for tests, aggregation of tests into collections, and independence of the tests from the reporting framework. The purpose of API Testing is to check the functionality, reliability, performance, and security of the programming interfaces. You can use unittest or other third-party libraries such as pytest to achieve the same results. Now, let's take a look at what it takes to integrate with a REST API using Python Requests. The tool comes with different plugins for popular CI servers. Each request returns a dictionary. Before moving forward, let's unit test those functions. Path One: Make HTTP request with json & requests libraries. Chapter 6 - Response Schema Validation. One of the topics that was covered in this course is writing tests for RESTful APIs using the Python requestslibrary and the pytestunit testing framework.

And that all we need to get started with building our framework. 2. 3. To find tests, nose2 looks for modules whose names start with test in the current directories and sub-directories. For this tutorial, we will be communicating with a fake API on JSONPlaceholder. Creating a Test Plan. Chapter 3 - Fluent Assertions. Testing Post Request With Python You can also test a post endpoint of an API using Python's requests.post. The API call returns a JSON string, so the JSON library will be used for conversion to the python data structures.
