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.

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

2. Which is the most useful tool listed above?
