module Kernel

Describe a series of expectations for a given target desc.

Defines a test class subclassing from either Minitest::Spec or from the surrounding describe’s class. The surrounding class may subclass Minitest::Spec manually in order to easily share code:

class MySpec < Minitest::Spec
  # ... shared code ...
end

class TestStuff < MySpec
  it "does stuff" do
    # shared code available here
  end
  describe "inner stuff" do
    it "still does stuff" do
      # ...and here
    end
  end
end

but do note that several items there are debatable or specific to rspec.
