add_teardown_hook

Adds a block of code that will be executed after every TestCase is run. Equivalent to teardown, but usable multiple times and without re-opening any classes.

All of the teardown hooks will run in reverse order after the teardown method, if one is defined.

The argument can be any object that responds to #call or a block. That means that this call,

MiniTest::TestCase.add_teardown_hook { puts "foo" }

… is equivalent to:

module MyTestTeardown
  def call
    puts "foo"
  end
end

MiniTest::TestCase.add_teardown_hook MyTestTeardown

The blocks passed to add_teardown_hook take an optional parameter that will be the TestCase instance that is executing the block.
