Istanbul has been a godsend for my company's JS-based projects. When paired with grunt-contrib-jasmine, it gives instant visibility into how much of the client-side app is actually under test, and gives everyone an incentive to keep improving coverage.

#12Great tool, perfectly fits to the node.js ecosystem, lightweight and fast.
However in case you use co-mocha[1] to test your generators, istanbul won't work properly, the generators in the reports are shown as uncovered. Therefore I made a mocha fork[2] and directly applied the changes from co-mocha to the source (instead of monkey patching); it solved the problem.

#13I'm a fan of mocha + blanket for coverage: https://github.com/alex-seville/blanket
The mocha integration is incredibly easy:
mocha --require blanket -R html-cov # for html outputRe: Istanbul: A JavaScript code coverage tool written in JS
#14i have some projects where the meat is in a cross domain connector. no way to test it in units. only functional test in real browsers cut it. otherwise it's just red tape testing.
there is zero coverage tool for this case, until browsers wake up and give me a decent Dev api like opera 12 allowed

#15In case it's useful for anyone, here is a gist of a gulpfile I use to use Istanbul to instrument my Node.js app, then run tests with Mocha and output the results: https://gist.github.com/medatech/76c6017cf55630b2db08
or you could just write it as a single CLI command: https://github.com/strongloop/express/blob/master/package.js...

#16Why did you name it Istanbul?

It made me think of the Neil Simon song.

#17Wasn't this project originally called "Constantinople"?

Surely, the question you mean to ask is if it was originally called "Byzantium".
