[RFC] Switch to JavaScript about centipede

[akovalyov]

My two cents.

I am not sure if PhantomJS is good enough for that job, it sometimes gives false-negative due to internal failures, so probably CasperJS/ZombieJS can do the job well here.
But my question is - why should we tie to a specific browser/engine? Why not https://www.npmjs.com/package/selenium-webdriver or any other JS browser driver?

[umpirsky]

Good point. If possible we can use selenium webdriver. I have also seen other js drivers which can be handy for this purpose.

I just want to figure something that will make plugins like #26 easy to implement (without reinventing the wheel), since this was the biggest blocker with PHP implementation.

[umpirsky]

I just had a closer look at both. CasperJS looks like exactly what we need, and is easier to work and create plugins with.
