• Integrate with codecov to push code coverage data to codecov

Well, there was some work done with code coverage just recently: #206

I was planning to fiddle with it, to get it working properly. But haven't found time right now, so @abouthiroppy ended up closing the PR for now. The only thing really needed to do for it is to separate out the system tests from unit tests, and then enable the code coverage only for the latter.

Yep. If you have nice idea, I would like to try it.

[addityasingh]

@nene Sure. I will put some time later today to separate them out and then try running them. My suggestions:

• Use separate npm commands for running unit test and system tests. E.g. npm run test and npm run system-test
• Use a name convention like *.spec.js or ``*.test.jsfor unit test and retain the*Test.js` for system tests

Let me know what you guys think.

@nene How do you think his idea?

Updated the description to add an existing reference

Rather than use a file-extension, I'd simply move the system tests to separate directory. And then npm run test and nps run system-test would simply execute tests in corresponding directories.

FYI: there's really just one system test test/binTest.js, however I still think a separate directory would serve it better.

[addityasingh]

Wonderful. I would try to move the system test to system-test and then create the scripts to run both the tests separately
