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.

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

2. Which is the most useful tool listed above?
