Add more possible ENV variables for tests

[clayallsopp]

Adds some parity to Rails + RSpec options

What's the benefit of having these different names?

[clayallsopp]

it's annoying when switching from Rails to remember that RubyMotion's spec task has a different ENV variable for specifying specific tests

[clayallsopp]

and not just Rails - I'm unaware of any other Ruby testing lib which uses files as a filter variable

I can see that being helpful. Could you please point me to the docs for both env vars? I'm unable to easily find the canonical ones.

Rails/Rake: http://ruby-doc.org/stdlib-2.0.0/libdoc/rake/rdoc/Rake/TestTask.html

If rake is invoked with a “TEST=filename” command line option, then the list of test files will be overridden to include only the filename specified on the command line.

Rspec: https://github.com/rspec/rspec-core/blob/918d2059b3b14ef670e5bec3de7ba83925fdf559/lib/rspec/core/rake_task.rb#L112

Perfect, thanks!

👍 Do we add this?

And I think we can deprecate files option.
