The below code produces a NullPointerException when I run it. Which is weird because shouldn't the setup() method be ran before the tests?

If I instantiate the AirJourney class within the test method the JUnit test passes without any problems. What am I missing?

private AirJourney journey;

    @Before
    public void setup()
    {
        journey = new AirJourney(4, 800, "A", "B");
    }

    @Test
    public void testCorrectCostIsProduced()
    {
        assertEquals(32000, journey.calculateCostOfJourney());
    }

Did you miss `@RunWith(MockitoJUnitRunner.class)` or `MockitoAnnotations.initMocks(this)`? – Thiyagu Jul 23 '18 at 18:05
Where does that NPE occur? – ernest_k Jul 23 '18 at 18:06
@ernest_k The call to `journey.calculateCostOfJourney()` – Jakemangan1 Jul 23 '18 at 18:08
