We need to do a headless testing of a project using Selenium + PHPUnit for which PhantomJS is a natural choice. However, they currently have a major issue with the recent Selenium Server and no maintainers for the Ghostdriver, not to mention that PhantomJS itself is undergoing pretty significant changes for v2.0. So PhantomJS will not be a viable option for at least a few months.
Is there any solid alternative to this? I've heard of HtmlUnit(Driver) but that seems like a pretty old project with its own issues. Other ideas?
