JSCoverage is a tool that generates code coverage statistics for JavaScript. This information is useful for designing tests that exercise all parts of a JavaScript program.
JSCoverage works by instrumenting the JavaScript code used in web pages. Code coverage statistics are collected while the instrumented JavaScript code is executed in a web browser.
JSCoverage works with any modern standards-compliant web browser - including Internet Explorer (IE 6 and IE 7), Firefox, Opera, and Safari - on Windows and Linux.
JSCoverage is free software, distributed under the GNU General Public License.
