New Releases Lead to Better Ruby Testing
The last week or so has seen new releases of two of my favorite additions to testing (or speccing if you're of the BDD persuasion) in the Ruby world. zenspider and Kevin Clark have released a new version of Heckle on the 20th, and Mauricio Fernandez released a new version of rcov this morning (the 21st).
heckle is a tool that 'tests your tests', walking the AST that Ruby executes for the code under test and transforming (or mutating) it to ensure that your tests still fail if an if is changed to an unless, or if inputs to methods being tested are changed. It provides an informal measure of branch coverage for your test suite. This release features better readability (through unified diff output of failing mutated tests and simple reporting at the end of heckle runs. Kevin tells me they're working on HTML report generation as well, which I think will be a great addition.
rcov is a more traditional tool, it measures line coverage of your test suite. This release includes: an annotation mode (--annotate), which reprints the original source with coverage annotations; enhanced emacs support (including jumping to uncovered code); and a number of bugfixes including a segfault when running under rspec.
It's been a good week for Ruby testers. Hopefully March will continue the trend.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
