This tutorial will be your gentle guide to property-based testing. Property-based testing is a testing philosophy; a way of approaching testing, much like unit testing is a testing philosophy in which we write tests that verify individual components of your code.
By going through this tutorial, you will:
- learn what property-based testing is;
- understand the key benefits of using property-based testing;
- see how to create property-based tests with Hypothesis;
- attempt a small challenge to understand how to write good property-based tests; and
- Explore several situations in which you can use property-based testing with zero overhead.
What is Property-Based Testing?
In the most common types of testing, you write a test by running your code and then checking if the result you got matches the reference result you expected. This is in contrast with property-based testing, where you write tests that check that the results satisfy certain properties. This shift in…
