I want to be able to use the html-cov
reporter, even though the tests are passing, all the coverage values are 0.
I'm using Grunt, Istanbul for creating the instrumented code and mocha for the tests, this is my grunt file
module.exports = (grunt) ->
release = (type = 'develop') ->
switch type
when 'master'
grunt.task.run('release')
else
grunt.config.set('release',
options:
tag : false
pushTags: false
npm : false
)
grunt.task.run('release')
return
grunt.initConfig
pkg: grunt.file.readJSON 'package.json'
covervars:
base : 'tests/lib-cov'
build : '<%=covervars.base %>/build'
reports: '<%=covervars.base %>/reports'
watch:

tasks: ['build']

The instrumented code looks like this: http://pastebin.com/3wAt5VZT
a part of the istanbul lcov.info file (that is correctly generated)

mocha doesn't seem to be picking up the test coverage, but if I enable storeCoverage
and makeReport
, instabul is showing me the correct number of files and the % of code used in each file. is mocha only able to use coverage from jscoverage? if not, am I missing any steps?
