I'm trying to run some unit tests on some Data objects that I use in Spring.

I set up my unit test like this:

@ExtendWith(SpringExtension.class)
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
@TestPropertySource(
        locations = "classpath:application.properties")
@JdbcTest
public class TestInventory {

    @Autowired
    DataSource dataSource;

    @Test
    public void testFinishedGoods() throws SQLException {
     ....
    }
}

I'm getting an error because in one of my Data Objects I access a cache like this:

var ctx = ApplicationContextProvider.getApplicationContext();
CacheRepository cacheRepository = ctx.getBean(CacheRepository.class);
Currency currencyObj = cacheRepository.getCurrencyList().stream().filter(cur -> cur.identity() == currency).findFirst().orElseThrow();
currencyRate = currencyObj.rate();

This works fine in the web app, but in JInit I get:

java.lang.NullPointerException: Cannot invoke ".springframework.context.ApplicationContext.getBean(java.lang.Class)" because "ctx" is null

I implemented ApplicationContextProvider as ApplicationContextAware which works fine. Only JUnit has a problem.

Any ideas?

• java
• spring
• junit

I solved it by removing @JdbcTest and then added

@SpringBootTest(classes = MyApplication.class) 

The final set of annotations I used:

@ExtendWith(SpringExtension.class)

@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)

@TestPropertySource(locations = "classpath:application.properties")

@ContextConfiguration(classes = TestInventory.class)

@SpringBootTest(classes = MyMainApplication.class)
