The locale config is set in application.rb from environment variables
already. We don't need to repeat that logic in test.rb. And because it
was outdated, the language switcher was actually broken in the test
environment. We did have an English selector for the fallback `en` even
though we were already displaying English as en_TST. And after
switchting to Spanish, we could switch back because en_TST was not in
the available locales.
I now fixed the test with the right assumption and the config to solve
the problem.
Rails 4.1 added time helpers but we never bothered using them. But now
I'm getting rid of the Timecop dependency and use standard helpers.
Beware though that the new helpers always freeze time. When you travel
to a certain date then the clock stops ticking while Timecop maintained
the passing of time.
The freezing of time could cause problems if you are trying to enforce a
timeout. But all current specs don't seem affected.
In most cases, the freezing will make it easier to avoid flaky specs.
The default action when a user submit the form too quickly is to
redirect to :back with flash error message. As we are using CableReady
it's not working for us, so I render_alert_timestamp_error_message
to show the error message to the user.
