Simple example repo for Lest

This repo is a simple example of how to use the Lest testing framework, which you can find at https://github.com/TAServers/lest.

The program itself simply prints the sum of 1 and 2 to console.

Run the tests locally by downloading the latest release bundle for Lest and running lua lest.lua from the project directory. You can run it with a working directory elsewhere, but you will need to manually set the config path when invoking Lest and update the config to match the tests correctly.

Structure

• .github/workflows/test.yml - GitHub workflow which tests the program on commit using the Lest GitHub Action
• src/ - The source code for the program
  • main.lua - Entrypoint of the program
  • main.test.lua - Unit tests for main.lua. Showcases module and function mocking
  • sum.lua - Dependency of main.lua that exports a function which returns the sum of two numbers
  • sum.test.lua - Unit tests for sum.lua. Very simple example of unit testing with no mocking.
• tests/ - Tests for the program that don't specifically relate to a single source file (integration, end to end etc.). A convention and not a requirement of Lest
  • integration.test.lua - Simple integration test of the whole program
• .gitignore - Used to ignore a local copy of Lest in this instance
• lest.config.lua - Contains configuration options for Lest,
