问题 I'm trying to test amending text in an editable input which contains the title of the current record - and I want to able to test editing such text, replacing it with something else.

问题 Is there any headless browser that support geolocation? I know Phantomjs doesn't support that feature. If no, how programs that uses geolocation (prey project & lockit tight) work?
