Hi there, we have a project using Ruby on Rails 4.2 (Ruby 2.3). We are having problems getting some of our Capybara feature test through. They seem to break completely randomly (so when I re-run by ssh-ing into the machine, most of the time a different test breaks, sometimes more than one). We are using the free container, could it be that I need more cores to run these type of tests? Not sure how to debug it. Non of our developers has problems with running these tests locally.
