[jbosstools-issues] [JBoss JIRA] (JBDS-3850) Test code coverage console report for platform installer unit tests

[Pavol Pitonak (JIRA)]

    [ https://issues.jboss.org/browse/JBDS-3850?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13196346#comment-13196346 ] 

Pavol Pitonak commented on JBDS-3850:
-------------------------------------

[~dgolovin], [~jrichter1] these are my findings so far:

* I found two live JS code coverage tools - [Istanbul|https://github.com/gotwarlost/istanbul] and [JSCover|http://tntim96.github.io/JSCover]
* JSCover is implemented in Java, Istanbul is implemented in JavaScript
* Istanbul seems to be preferred by JS community
* Istanbul can be integrated with Mocha, Jasmine and Karma

I suggest that we use *Istanbul*

We have 3 types of tests that should generate code coverage statistics:
# unit tests - multi-platform, they only need Node.js, launched using Mocha, run on _npm test_
# browser tests - multi-platform, they need Node.js, launched using Karma, they test Angular-specific code (directives etc), run on _npm test_
# ui tests - platform-specific, run with built installer binary, using Protractor, run on _npm run ui-test_

For now, I only focused on unit tests.

I have PoC on my feature branch but 
# I was not able to run it with Babel 5
# when we want to upgrade to Babel 6, we either need to wait for JSPM 0.17 (cannot estimate when will be released) or remove JSPM completely (JBDS-3769) which is half-way done on my feature branch (only need to fix Karma tests)
# when I removed JSPM, I still need to use latest development release of Istanbul (1.0.0-alpha.2) instead of latest stable release (0.4.3)

[~dgolovin], [~jrichter1] how do we want to proceed?

> Would be good to have code coverage report for unit tests to see how reliable tests are
