Quixotic
^^^^^
**Definition:**

* A test that charts an idealistic path through the subject code, cherry-picking inputs that provide minimum resistance (e.g. in test data setup), which may result in missed test coverage in code that handle negative cases. Notably, this is more likely to occur when those negative cases are also somehow complex, which is precisely when good testing is important!

**Code Example:**

.. code-block:: ruby
  
  # Subject under test
  def rank_hotel_review(user, title, text, stars)
    rank = 10
    rank -= 3 unless user.logged_in
    rank += 10 if stars == 5 || stars == 1
    if rank > 1 && obscene?(title)
      raise "Underage swearing!" unless user.age > 13
      rank = 1
    elsif rank > 3 && obscene?(text)
      rank = 3 unless user.occupation == "sailor"
    end
    return rank
  end

  # Test
  class Quixotic < SmellTest
    def test_5_star_member
      user = OpenStruct.new(logged_in: true)

      result = rank_hotel_review(user, "title", "body", 5)

      assert_equal 20, result
    end

    def test_3_star_anonymous
      user = OpenStruct.new(logged_in: false)

      result = rank_hotel_review(user, "title", "body", 3)

      assert_equal 7, result
    end
  end

  # Fake production implementations to simplify example test of subject
  def obscene?(text)
    text.include?("obscenities")
  end
