Jest Lua

Delightful Lua Testing.

---

Jest Lua can currently only run inside of Roblox. Help is wanted to get it running in other Lua environments, such as Lune or Luvit. See issue #2.

Roblox uses Jest Lua internally for testing their apps, in-game core scripts, built-in Roblox Studio plugins, as well as libraries like Roact Navigation. This library should be considered battle-tested and ready for production use.

Installation

Add this package to your dev-dependencies in your wally.toml, for example:

1JestGlobals = "jsdotlua/jest-globals@3.10.0"

Then, require anything you need from JestGlobals:

1local JestGlobals = require("@Packages/JestGlobals")
2local expect = JestGlobals.expect

Inspiration and Prior Work

Jest Lua is a Lua port of the open source JavaScript testing framework Jest. Modules in the modules directory are aligned to v27.4.7 of Jest.
