Property based testing is a way to stochastically generate test data.
It can be used for at least two things:
- To really pry into the edge-cases of a system
- To investigate where a bug exists in a pre-existing complex system
There may be more use cases, but this is what we're gonna focus on today.
The following are what I've confirmed it to work on. It may well work on lower versions or higher versions. If you succesfully use a version outside these requirements, please let me know and I'll add it
- node v12.13.1
- npm v6.12.1
You should be comfortable writing code in typescript and comfortable using jest assertions.
It would also help to have some knowledge of how recursion works
npm install
In the exercises directory, you'll find a number of exercises along with their solutions split into several directories. Each has its own README.md and the tests for each can be run with npm run ex-{x}. Please head over to exercise-1 to get started
