Assert SQL Count

The library contains SQL statement validator that helps to verify count of queries generated by Hibernate.

Code Example

There are two options:

1. Using AssertSqlCount class

@RunWith(SpringRunner.class)
@SpringBootTest(classes = UserQueryServiceApplication.class)
public class UserControllerTest {

    @Before
    public void before() {
        AssertSqlCount.reset();
    }

    @Test
    public void shouldFindUser() throws Exception {
        User user = userRepository.findOne("1");
        user.getOrders().size();
        AssertSqlCount.assertInsertCount(1);
    }
}

2. Using matcher

@RunWith(SpringRunner.class)
@SpringBootTest(classes = UserQueryServiceApplication.class)
public class UserControllerTest {

    @Before
    public void before() {
        AssertSqlCount.reset();
    }

    @Test
    public void shouldFindUser() throws Exception {
        User user = userRepository.findOne("1");
        user.getOrders().size();
        assertThat(queryCounts(), hasSelectCount(1));
    }
}
