I find it extremely hard to write @SpringBootTest if you use @ComponentScan and Jpa repositories. Can someone advice? This should be super-trivial stuff, but it's not documented anywhere.

@SpringBootApplication   @ComponentScan(        excludeFilters = {                @ComponentScan.Filter(type = FilterType.CUSTOM, classes = TypeExcludeFilter.class),                @ComponentScan.Filter(type = FilterType.CUSTOM, classes = AutoConfigurationExcludeFilter.class) },        basePackageClasses = {Main.class, Other.class}) public class Main {    public static void main(String[] args) {        SpringApplication.run(Main.class, args);

and one of discovered Configuration classes has:

@Configuration @EnableJpaRepositories("jpa")

Now I want to create test , which will enable ideally just a subset of JPA repositories AND exactly nothing else, unless I tell so. Namely, no configuration from production source code. This seems to be close to impossible to express. This is where I was able to get:

@RunWith(SpringRunner.class) @SpringBootTest @Import(TestIT.TestConfig.class) public class TestIT {    @Configuration    @EnableJpaRepositories("jpa")    @AutoConfigureDataJpa    @AutoConfigurationPackage    public static class TestConfig {        //here will be beans for test.    }


so this configuration produces error

java.lang.IllegalArgumentException: Not a managed type ...my jpa repository class

which probably means, that jpa package isn't among autoconfigured packages. No idea how to add it if it's even possible.

OK, another approach. Some sources recommends this:

@RunWith(SpringRunner.class) @SpringBootTest @Import(TestIT.TestConfig.class) public class TestIT {    EnableJpaRepositories("jpa")    @EntityScan(basePackages = "jpa.entities")    //@TestPropertySource("classpath:application.properties")    @EnableTransactionManagement    public static class TestConfig {        //here will be beans for test.    }

but this one fails with caused by: java.lang.IllegalArgumentException: At least one JPA metamodel must be present!

Any hints?
