jscoverage tool, both node.js or javascript support, only used for pixbi

npm install pixbi-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 select list or spec or tap reporter in mocha

mocha -r jscoverage -R spec test/

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

full modelł:

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

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 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,*.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

var testMod = 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

The follow object will be detected, all of them are created by jscoverage.
