### Install
|
|
|
|
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.
|
|
|
|
/* directory */
|
|
"coverage": "mv lib lib~; (jscoverage lib~ lib; mocha -R html-cov > coverage.html); rm -rf lib; mv lib~ lib"
|
|
|
|
/* 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"
|
|
|
|
### 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.
