Pick an issue to fix, or pitch new features. To avoid wasting your time, please ask for feedback on feature suggestions either with an issue or on the mailing list.

The Sinon.JS developer environment requires Node/NPM. Please make sure you have Node installed, and install Sinon's dependencies:

$ npm install

$ npm test

Open test/sinon.html in a browser. To test against a built distribution, first make sure you have a build (requires Ruby and Juicer):

$ ./build

Then open test/sinon-dist.html in a browser.

If the build script is unable to find Juicer, try

$ ruby -rubygems build

Some tests needs working XHR to pass. To run the tests over an HTTP server, run

$ node_modules/http-server/bin/http-server

Then open localhost:8080/test/sinon.html in a browser.

The Rhino tests are currently out of commission (pending update after switch to Buster.JS for tests).
