Bun Test Basics

A practical reference for Bun's built-in test runner that covers the everyday stuff you'll actually use. You get the core syntax for describe/it blocks, common matchers like toBe and toEqual, test modifiers like skip and only, and parameterized tests with test.each. The CLI options section is helpful for setting timeouts and running tests concurrently. It's Jest-compatible, so if you know Jest the transition is smooth. The matcher examples are comprehensive enough that you won't need to context switch to docs for basic assertions. Load this when you're writing tests in Bun and need a quick syntax check or want to remember how test.each works with objects.
