JavaScript

A JavaScript Testing Framework

Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it’s suited for websites, Node.js projects, or anywhere that JavaScript can run.

Installation

There are several different ways to install Jasmine, depending on your
environment and how you’d like to use it. See the Getting Started page
for details.

Usage

See the documentation site,
particularly the Your First Suite tutorial
for information on writing specs, and the FAQ.

Supported environments

Jasmine tests itself across popular browsers (Safari, Chrome, Firefox, and
Microsoft Edge) as well as Node.

Environment	Supported versions
Node	18, 20, 22
Safari	15-17
Chrome	Evergreen
Firefox	Evergreen, 102, 115, 128
Edge	Evergreen

For evergreen browsers, each version of Jasmine is tested against the version of the browser that is available to us
at the time of release. Other browsers, as well as older & newer versions of some supported browsers, are likely to work.
However, Jasmine isn’t tested against them and they aren’t actively supported.

* Environments that are past end of life are supported on a best-effort basis.
They may be dropped in a future minor release of Jasmine if continued support
becomes impractical.

To find out what environments work with a particular Jasmine release, see the release notes.
