jscoverage tool, both node or javascript support
npm install jscoverage -g
git clone git://github.com/fishbar/jscoverage.git
cd ./jscoverage
mocha -R list test --coverage
jscoverage
# print help info
jscoverage source.js
# convert source.js to source-cov.js
jscoverage source.js dest.js
# convert source.js to dest.js
jscoverage sourcedir destdir --exclude a.js,b.js,c.js
# convert all files in sourcedir to destdir, exclude list will be ignoredTODO, comming soon
jscoverage sourcedir destdir --no-instrumentvar jsc = require('jscoverage');
var abc = jsc.require(module, 'testmodule.js');
describe('test', function () {
// TEST CODE HERE
});==== or =====
var jsc = require('jscoverage');
require = jsc.mock(mo);
var abc = require('abc.js', true);
describe('test', function () {
// TEST CODE HERE
});jscoverage do not process coverage by default, because when we writting test case in the begining, case always fail, and we need to fix problems by check the error stack, finding the exact line where error happened
using follow options, you can switch the functions
--coverage enable coverage action, default nocoverage
--noinject close inject action, default inject , sometimes you already using rewire module do the same thing
i.e when you run test code by mocha:
mocha test/ --coverage # open coverage instrument
mocha test/ --noinject # close inject when you are using rewireor you can also do in this way:
var jsc = require('jscoverage');
jsc.enableCoverage(true);
jsc.enableInject(false);output a html coverage reporter
mocha -R html-cov test/test.js --coverage > coverage.htmlyou can just print the coverage info in cli , like this:
// add the following code to you test file
var jsc = require('jscoverage');
process.on('exit', function () {
jsc.coverage(); // print summary info, cover percent
jsc.coverageDetail(); // print uncovered lines
});the follow object will be detected, all of them are create by jscoverage
