module Minitest::Guard - minitest: Ruby Standard Library Documentation

# module Minitest::Guard

Provides a simple set of guards that you can use in your tests to skip execution if it is not applicable. These methods are mixed into `Test` as both instance and class methods so you can use them inside or outside of the test methods.

    def test_something_for_mri
      skip "bug 1234"  if jruby?
      # ...
    end

    if windows? then
      # ... lots of test methods ...
    end
