incorrect cobertura report for es6 codes run by babel-node #734

babel-node ./node_modules/istanbul/lib/cli.js cover tests/jasmine-runner.js report cobertura

See from both console output and lcov report, the coverage summaries are 100%.

Statements : 100% ( 107/107 ) Branches : 100% ( 27/27 ) Functions : 100% ( 37/37 ) Lines : 100% ( 105/105 )

But look from the cobertura report, it shows as below:

Packages ------- Files ------------ Classes -------- Methods ------------- Lines -------- Conditionals 100% (7/7) -- 100% (15/15) -- 100% (15/15) -- 52% ()94/181 ----- 67% (392/588) ----- 100% (0/0)

Many babel compiled code like anonymous_x methods are counted in unexpectedly.

void (anonymous_0)()
0%
0/1 N/A void (anonymous_1)()
0%
0/1 N/A void (anonymous_13)() 0%
0/1 N/A void (anonymous_17)() 0%
0/1 N/A void (anonymous_18)() 0%
0/1 N/A void (anonymous_19)() 0%
