tape - tap-producing test harness for node and browsers

•    Javascript

---

Depending on the module you're loading, you may be able to paramaterize it using environment variables or auxiliary files. Babel, for instance, will load options from .babelrc at runtime.The -r flag behaves exactly like node's require, and uses the same module resolution algorithm. This means that if you need to load local modules, you have to prepend their path with ./ or ../ accordingly.

Ava - Futuristic JavaScript test runner

•    Javascript

---

AVA is a test runner for Node.js with a concise API, detailed error output, embrace of new language features and process isolation that lets you develop with confidence. AVA automatically detects whether your CI environment supports parallel builds. Each build will run a subset of all test files, while still making sure all tests get executed. It automatically removes unrelated lines in stack traces, allowing you to find the source of an error much faster.

js-must - An assertion library for JavaScript and Node

•    Javascript

---

Must.js is a testing and assertion library for JavaScript and Node.js with a friendly BDD syntax (awesome.must.be.true()). It ships with many expressive matchers and is test runner and framework agnostic. Follows RFC 2119 with its use of MUST. Good and well testsed stuff. For those new to testing JavaScript on Node.js, you'll also need a test framework (also called a test-runner or a harness) to run your tests. One such tool is Mocha.
