KO!

KO! (aka Knockout) is a next-generation unit testing framework for the Ruby programming language. What makes KO! so modern?

• Clear and concise syntax.
• No assertions framework required!
• Rapidly test multiple parameter sets on a test scenario.
• Reusable contexts (before, after, etc).
• Easily stage test fixture files.
• And yes, it eats it's own dog food.

KO reads like a developer thinks. More specifically, KO! breaks down the systems analysis proccess into clear and obvious divisions. KO "specifications" are divided-up into test cases, contexts, concerns and test assertions.

• Test Cases delineate the overall requirement that is to be demonstrated.
• Contexts are used to setup and teardown test fixtures.
• Concerns break-up testcases into separate areas of concern.
• Test Assertions compose the proof of a testcase as a set of assertions.

Here is simple example.

    KO.case "example" do

      test "equality" do |a,b|
        a == b
      end

      ok 1, 1.0
      no 1, 2.0

    end
    

KO! was inspired in part by the void left behind by the discontinuation of Shoulda as a test framework. It seemed like an opportune time to give Ruby an elegant, modern and light-weight test framework to serve as an alternative to the monolithic RSpec.

Future versions of KO! may also support Lemon's unit test coverage system.
