trap is a minimalist JavaScript test framework for Node that builds on the simplicity of **node‑tap** or **tape** while adding Mocha‑style extensibility. It provides just two core concepts—`test` blocks and `t.cb` for effortless async handling (also supports promises)—and works with any assertion library or plain exceptions, making it ideal for developers who want a lightweight, zero‑configuration testing tool that runs both single files and whole suites via a CLI.
