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.

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

2. Which is the most useful tool listed above?
