I don't think this gen is maintained anymore.

Capybara::Screenshot is not supported for now. See mattheworiordan/capybara-screenshot#142

[NishNutmeg]

Was wondering if anyone is maintaining this Gem.would be nice if someone does.

[KazuCocoa]

No one maintains this gem for now.(I've updated once to update ruby_lib.)

[KazuCocoa]

BTW, browser_initialized? is deprecated in Capybara. So, mattheworiordan/capybara-screenshot#142 will break, I guess.

I think the error is disconnect session related one, and in this case, taking screenshots is failed. We should catch the exception or skip Capybara commands because of disconnection.

---

I add an example to taking screenshot as after hook, though.

[KazuCocoa]

Anyway, to avoid this error, we need to add error handling in mattheworiordan/capybara-screenshot like the PR or add ignoring the error, or raising the other error?, in save_screenshot in appium capybara side, I suppose.
(But I don't like to add ignoring the general error in save_screenshot or the other method.)
