About Continuum for Karma/Jasmine

Continuum for Karma/Jasmine is an accessibility testing tool that allows developers to conduct automated accessibility testing using their existing Karma and Jasmine configuration.

Karma is a JavaScript test runner that can be used to spawn a web server which loads your application's source code and executes your tests. Karma is executed on the command line and will display the results of your tests on the command line once they have run in the browser. Jasmine is a behavior-driven development (BDD) framework to test JavaScript Code. Continuum for Karma/Jasmine provides developers with an easy and painless way to address accessibility concerns during the development process.

Continuum for Karma/Jasmine includes:

• Access Engine, specifically the automatic tests included with this accessibility testing engine
• A sample Continuum project that includes two tests on two elements using Karma and Jasmine
