JSCoverage is a tool that measures code coverage for JavaScript programs.

JSCoverage is a tool that measures code coverage for JavaScript programs.

Code coverage statistics show which lines of a program have been executed (and which have been missed). This information is useful for constructing comprehensive test suites (hence, it is often called test coverage).

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 supports the complete language syntax described in the ECMAScript Language Specification (ECMA-262, 3rd edition). JSCoverage works with any modern standards-compliant web browser - including Internet Explorer (IE 6, 7, and 8), Firefox, Opera, Safari, and Google Chrome - on Microsoft Windows and GNU/Linux.

JSCoverage is free software, distributed under the GNU General Public License version 2.

Karma coverage thresholds

I am currently using Karma's coverage within a project, I would like to enforce a threshold for the coverage to be set at and therefore make my builds on Circle CI to fail and go red due to it being lower than a set percentage.
