Long Test

Definition:

A Long Test is a test that consists of lot of code and statements. Such tests are mostly (but not necessarily) complex and badly document the purpose of the test and the application code. Furthermore they tend to test too much functionality, maybe even getting eager.

Also Known As:

Obscure Test

Code Example:

# Subject under test
class Stack
  def initialize
    @items = []
  end

  def push(item)
    @items << item
  end

  def pop
    @items.pop
  end

  def peek
    @items.last
  end

  def depth
    @items.size
  end
end

# Test
class Long < SmellTest
  def test_make_sure_everything_works
    subject = Stack.new

    # Test Push
    subject.push("A")
    subject.push("B")
    subject.push("C")

    assert_equal "C", subject.pop
    assert_equal "B", subject.pop
    assert_equal "A", subject.pop

    # Test Peek
    subject.push("D")
    subject.push("E")

    assert_equal "E", subject.peek

    subject.pop

    assert_equal "D", subject.peek

    subject.pop

    # Test Depth
    subject.push("F")
    subject.push("G")

    assert_equal 2, subject.depth

    # Test Pop
    subject.pop
    subject.pop

    assert_equal 0, subject.depth
    assert_equal nil, subject.pop
  end
end
