jscoverage tool, both node.js or javascript support

npm install jscoverage

from v0.5.0， jscoverage start using uglify2, and enhance the coverage range.now, jscoverage will find out which branch you missed!

using mocha loading the jscoverage module, then it's work:

mocha -r jscoverage test/

jscoverage will append coverage info when you selectlist orspec ortap reporter in mocha

mocha -r jscoverage -R spec test/

besides, you can use--covout to specify the reporter， likehtml,detail.thedetail reporter will print the uncovered code in the console directly.

full modelł:

mocha -r jscoverage --covignore .covignore --covout=html --covinject=true --coverage=90,85,75test

the cmd above means:

• mocha run test case with jscoverage module
• jscoverage will ignore files while list in .covignore file
• jscoverage will output a report in html format
• jscoverage will inject a group of function to your module.exports (_get, _set, _reset, _replace);
• jscoverage will switch the colorful output: 90%+ is greate, 85%+ is ok, lower then 75% coverage is terrible

jscoverage can recognise all options below:

 --covignore [filepath] # like gitignore, tell jscoverage to ignore these files --overrideIgnore [boolean] # set if override the build-in ignore rules --covout [output report] # can be:  spec, list, tap, detail, html --coverage [high,middle,low] # coverage level, default is: 90,70,30 , means 90% is high, 30% is low --covinject [boolean] # switch if inject code for easytest(exports._get, exports._replace, exports._reset)

default jscoverage will search .covignore in the project root

jscoverage# print help infojscoverage source.js# convert source.js to source-cov.jsjscoverage source.js dest.js# convert source.js to dest.jsjscoverage sourcedir destdir --exclude a.js,b.js,c.js,*.min.js# convert all files in sourcedir to destdir, exclude list will be ignored

jscoverage will copy exclude file from source dir to dest dir

vartestMod=require('module/for/test.js');testMod._get('name');testMod._replace('name',value);testMod._reset();testMod._call();

using bellow comment, jscoverage will ignore the following block/statement

/*@covignore */

comming soon
