How to go offline?

[aliciapaz]

I've been trying to find a way to test a PWA end-to-end using Cuprite as my driver, but I haven't find any way of either temporarily disabling the app server or switching the headless browser into offline mode.

I've seen some resources regarding this issue (stackoverflow, blog posts, etc.) but they all refer to Capybara + Selenium.

I'd appreciate your help on this!

There's no such ability now, but it can be easy to implement judging by this.

I'll try to take a stab soon

Was implemented in Ferrum and will land on Cuprite in the new release.
