 # Unit Tests Practice
 
-#### This repo explores a wide range of testing techniques — mocking, fixtures, test-class inheritance, a simulated HTTP server and continuous integration — using simple multiple-choice quizzes stored as JSON. It also compares the automated tests through unittest and pytest, and was also my first steps with Markdown documentation.
