## What it is
Jasmine is a behavior-driven development (BDD) testing framework for JavaScript that runs in browsers and Node.js. It provides a clean describe/it syntax with built-in assertions, spies, and mocks, with no external dependencies.

## Use cases
- write unit tests for javascript code
- test node.js applications with bdd style
- run browser tests for websites
- test javascript without external dependencies
- behavior driven development testing
- spy on and mock javascript functions in tests

## When to choose
- you want a batteries-included testing framework with assertions and mocking built in
- you need the same framework to test both browser and Node.js code
- you prefer BDD-style describe/it syntax without magic or transpilation

## When to avoid
- you need snapshot testing or a rich plugin ecosystem like Jest offers
- your project already uses another test runner and you only need an assertion library
- you want built-in code coverage reporting

## Facets
- artifact type: framework
- maturity: stable
- function: testing, e2e-testing, mocking
- domain: testing, developer-tools, web-development
- platform: browser, cross-platform
- tags: bdd, tdd, test-runner, assertions, spies, javascript, nodejs
