Fork of @ericboehs Poltergeist hack to silence CoreText performance notes from phantomjs My changes: 1. to is now optional parameter, if not provided @write_io is used 2. option to easily add more messages to suppress (I added this one WARNING: Method userSpaceScaleFactor in class NSView is deprecated)
module Capybara::Poltergeist
class Client

def redirect_stdout(to = nil)
to ||= @write_io
prev = STDOUT.dup
prev.autoclose = false
$stdout = to
STDOUT.reopen(to)
