Fire And Forget
^^^^^
**Definition:**

* A test that's at risk of exiting prematurely, typically before its assertions can run and fail the test run if necessary


**Also Known As:**

* Plate-Spinning


**Code Example:**

.. code-block:: ruby

  # Subject under test
  def load_user(id)
    path = "/users/#{id}"

    get(path) { |er, user|
      user.resolved_via = path
      yield er, user if block_given?
    }
  end

  # Test
  class FireAndForget < SmellTest
    include UnreliableMinitestPlugin

    def test_gets_user_and_decorates_path
      load_user(42) { |er, user|
        assert_equal "/users/42", user.resolved_via
        assert_equal "Jo", user.name
      }
    end
  end

  # Fake production implementations to simplify example test of subject
  def get(path)
    Thread.new do
      sleep 0.01 if rand < 0.5 # sometimes it takes time
      yield nil, OpenStruct.new(name: "Jo") if block_given?
    end
  end
