Ignore Poltergeist JavaScript Errors

Poltergeist with PhantomJS (<2.0) does not support JavaScript’s bind() method. This means that when executing an integration test that exercises JavaScript with the bind() method, an error will occur. If you cannot simply upgrade to a version of PhantomJS that supports bind(), then what can you do?

Ignore the error!

This can be achieved by placing the following rescue block in the appropriate place.

rescue Capybara::Poltergeist::JavascriptError

Use this in moderation. You want to make sure you don’t ignore actual JavaScript errors.
