**Definition:**

* Tests pass when the scenario they test is not really fulfilled

**Code Example:**

.. code-block:: java

  public class PriceCalculatorFactoryTest {
    SettingsService settings = mock(SettingsService.class);
    @Test
    public void shouldCreatePriceCalculator() {
      //given
      given(settings.getMinMargin()).willReturn(new BigDecimal(20));
      given(settings.getMaxMargin()).willReturn(new BigDecimal(50));
      given(settings.getPremiumShare()).willReturn(new BigDecimal(50));
      //when
      PriceCalculator calculator
      = new PriceCalculatorFactory(settings).create();

      //then
      assertThat(calculator)
      .isEqualTo(new PriceCalculator(new BigDecimal(20),
      new BigDecimal(50), new BigDecimal(50)));
    }
  }
