Invariant Examples

Overview

This repository functions as an accessible example for Foundry developers to experiment and learn about invariant testing.

This repository is a work in progress, and will be updated continuously. Issues with suggestions are encouraged!

Setup

This project was built using Foundry. Refer to installation instructions here.

git clone git@github.com:lucas-manuel/invariant-example.git
cd invariant-example
forge install

Running Tests

Foundry considers all functions that start with invariant_ to be invariant tests. To run them, you can use the following commands:

• To run open invariant tests: make open-invariant
• To run bounded invariant tests: make bounded-invariant
• To run unbounded invariant tests: make unbounded-invariant

Call Summaries

invariant_call_summary functions are not invariants, they are used to illustrate how the probability distribution of function calls within a given invariant test works.
