Overview

These subsets facilitate testing by using the ENV variables specified on the command line to indicate which tests to run. The ENV variables are set by rake, so this code implicitly assumes that you’re running your tests through rake.

end

#case_test(hash, &block) ⇒ Object

Case tests take a hash of testcases and expected values. Each pair in the hash will be passed to the block if type CASE_TEST is specified. Individual cases tests can be specified by providing a regexp in CASE; the testcase will run if the pretty-print of the testcase matches the provided regexp. Example:

case_test(
  [1,2,3] => 'an array testcase',
  '[1, 2, 3]' => 'the pretty print of the array',
  'another testcase' => 'some third testcase'
).do |testcase, expected|
   ...your test code...
end

ENV['CASE_TEST']=true  => all tests run
ENV['CASE']='1, 2, 3' => first two tests run
ENV['CASE']='another' => only last test runs
