* Avoid setTimeout in Node, because we don't need the overhead there. * Still call setTimeout in browsers to prevent the tab from being killed. * Use queueMicrotask in Safari, because it's dramatically faster than MessageChannel there. * Continue to use MessageChannel in other supported browsers becuase it's somewhat faster than queueMicrotask there. * Don't use setImmediate any more because there's a faster alternative in all supported envs. In jasmine-core's own test suite, this yields a roughly 50-70% speedup in Node, ~20% in Edge, and 75-90%(!) in Safari.
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 | 12.17+, 14, 16, 18 |
| Safari | 14-15 |
| Chrome | Evergreen |
| Firefox | Evergreen, 91 |
| 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.
To find out what environments work with a particular Jasmine release, see the release notes.
