Jasmine is an open source testing framework for JavaScript.[2] It 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 is heavily influenced by other unit testing frameworks, such as ScrewUnit, JSSpec, JSpec, and RSpec.[3]

Usage

Jasmine aims to be easy to read. A simple hello world test looks like the code below, where describe() describes a suite of tests and it() is an individual test specification. The name "it()" follows the idea of behavior-driven development and serves as the first word in the test name, which should be a complete sentence. Usage follows syntax similar to that of RSpec.

The code below tests this function 

function helloWorld() {
  return 'Hello world!';
}

and verifies that its output is indeed the text "Hello world!".

describe('Hello world', function() {
  it('says hello', function() {
    expect(helloWorld()).toEqual('Hello world!');
  });
});

Jasmine has a number of other features, such as custom matchers, spies, and support for asynchronous specifications.

History

The developers at Pivotal Labs for Jasmine previously developed a similar unit testing framework called JsUnit before active development of Jasmine.[4]
