jscoverage | JavaScript libraries | A small guide into installing [jscoverage](https://npmjs.com/package./jscoverage). Also see [mocha-blanket](./mocha-blanket). |
Install
Install via npm
npm install --save-dev jscoverage
Ignore output
echo coverage.html >> .gitignore
package.json
The coverage
task injects your source files (lib
) with jscoverage hooks, runs mocha -R html-cov
, then restores later.
{: .-setup}
/* directory */
"coverage": "mv lib lib~; (jscoverage lib~ lib; mocha -R html-cov > coverage.html); rm -rf lib; mv lib~ lib"
{: .-hard-wrap}
/* single file */
"coverage": "(cp index.js index.js~; jscoverage index.js; mv index-cov.js index.js; mocha -R html-cov > coverage.html); mv index.js~ index.js"
{: .-hard-wrap}
Run
npm run coverage
open coverage.html
Caveats
If you're using jsdom, be sure to expose the window._$jscoverage
variable into
the global
scope.
