Jasmine is an open source Behavior Driven Development (BDD) based testing framework for JavaScript. Jasmine aims to run on any Javascript-enabled platform, to not intrude on the application nor the IDE, and to have easy-to-read syntax.

It can be used in the Rails framework. Jasmine ships as a Rubygem and leverages familiar rake tasks and generators to automate common workflows. Jasmine is heavily influenced by other unit testing frameworks, such as ScrewUnit, JSSpec, JSpec, and RSpec; and has syntax very similar to RSpec.

Background

The Jasmine framework was developed since developers to address certain specific concerns in existing testing frameworks <ref name="Background">https://github.com/pivotal/jasmine/wiki/Background</ref>

• Many frameworks only work from within a browser.
• Many don't support testing asynchronous code like event callbacks.
• Some have syntax that's hard for JS developers or IDEs to understand.

Design Principles

The Jasmine developer community believes that a good JavaScript testing framework must follow these principles. <ref name="Background"/>

• should not be tied to any browser, framework, platform, or host language.
• should have idiomatic and unsurprising syntax.
• should work anywhere JavaScript can run, including browsers, servers, phones, etc.
• shouldn't intrude in your application's territory (e.g. by cluttering the global namespace).
• should play well with IDEs (e.g. test code should pass static analysis).

Goals

The Jasmine framework is written with the objective of meeting these goals.<ref name="Background"/>

• it should encourage good testing practices.
• it should integrate easily with continuous build systems.
• it should be simple to get started with.
