**Definition:**

* Tests that are not maintained after SUT code evolution and still pass


**Code Example:**

.. code-block::

  public class TransactionTest {
    @Test
    public void shouldRecognizeTransactionsWithZeroValueAsInvalid() {
      //given
      Transaction tx = new Transaction(BigDecimal.ZERO,
      new InternalUser());
      //when
      boolean actual = tx.validate();
      //then
      assertThat(actual).isFalse();
    }
    
    @Test
    public void shouldRecognizeTransactionWithNegativeValueAsInvalid() {
      //given
      Transaction tx = new Transaction(BigDecimal.ONE.negate(),
      new InternalUser());
      //when
      boolean actual = tx.validate();
      //then
      assertThat(actual).isFalse();
    }
  }
