busted is an elegant, easy-to-use unit testing framework for Lua (5.1+, LuaJIT, Moonscript, Terra) with a natural, readable spec style. It offers extensible chained asserts, spies/stubs/mocks, nested describe blocks with tags, async tests, and modular output formats including TAP and JSON for CI integration.

Use cases

• write unit tests for lua code
• test lua modules with describe/it specs
• mock and spy on lua functions
• run lua tests in CI with TAP output
• extend assertion library with custom matchers
• test moonscript projects

When to choose

• you need a mature, widely adopted Lua testing framework
• you want readable BDD-style specs with chained assertions
• you need built-in spies, stubs, and mocks
• you need CI-friendly output formats like TAP or JSON

When to avoid

• you are testing non-Lua languages
• you need property-based or fuzz testing
• you want a zero-dependency test runner without LuaRocks
