javascript coverage without unit tests

Question

In a legacy webapp, we haven't any unit test on the javascript part.
We want to increase the code quality and delete dead code.
Is there any way to have line-by-line Javascript code coverage statistics in the browser during human test ? Is it possible to do that with istanbul for example ?

Answer 1

Executing every use case in a single human testing session could be painful, I don't recommend this approach. There is a lot of automated integration test framework like http://casperjs.org or http://nightwatchjs.org with which you can code your test scenario in a close to human semantic.

Imo, automation is not a waist of time ;)
