What it is
Jasmine is a testing framework for JavaScript, written in the behavior-driven development style, where tests are written as readable descriptions of expected behavior. The README says it does not depend on browsers, the DOM, or any other JavaScript framework, so it can be used for websites, Node.js projects, or anywhere JavaScript runs.
- Write unit tests for JavaScript functions in a Node.js project
- Test JavaScript that runs in a browser using the standalone release
- Organize tests into suites and specs with readable descriptions
Great for
- JavaScript developers who want a test framework with no extra dependencies
- Teams testing Node.js projects
- Developers testing browser-based websites
- People who prefer test descriptions written in plain, readable sentences
Not ideal for
- People who need a graphical testing tool with no coding (tests are written as JavaScript code)
- Projects that need browser or environment support outside the listed versions, since the README says other setups are untested
How to get it
