Order Dependent Tests
^^^^^
**Definition:**

* The tests have to be executed in a certain order due to dependencies between them.


**Also Known As:**

* Chained Tests, Chain Gang


**Code Example:**

.. code-block:: ruby

  class AnimalTest < Test::Unit::TestCase

    def test_create_record
      a = Animal.create!(name:"Lion")
      assert_not_nil a
    end

    def test_find_record
      a = Animal.find_by_name("Lion")
      assert_not_nil a
    end
    
  end
