Cloud-based Ruby tools

1. Assuming all of the following tools were available as cloud-based tools (and therefore fast, easy to set up, and easy to schedule), which would be useful to you or your team?

Please select all that apply.

	Unit test runner
	Product code vs. test code ratio
	Ruby runtime compatibility (e.g. Ruby 1.8, Ruby 1.9, JRuby, Rubinius)
	Rails compatibility (e.g. version 1.2, 2.1, edge)
	Test quality (e.g. Heckle)
	Average assertions/expectations per test
	Code complexity (e.g. Flog)
	Lines of code (per method, per class)
	Code coverage (e.g. RCov)
	None (cloud-based tools don't interest me)
	Something else (please describe)

2. Which is the most useful tool listed above?
