Spring integration tests : how to use context-caching?

Question

I have a base class for all my integration tests, which is something like this :

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)
@ContextConfiguration(classes = {Config1.class, Config2.class})
@TestPropertySource(properties = {
        "zonky.test.database.postgres.docker.image=my-image",
        "spring.profiles.active=test"
})
@AutoConfigureEmbeddedDatabase
public abstract class IntegrationTestBaseConfiguration {
}

Now, in each individual test class I have :

@ContextConfiguration(classes = {Config3.class})
class ConcreteIntegrationTest extends IntegrationTestBaseConfiguration {

  //tests
}

I want to know if the context defined in the IntegrationTestBaseConfiguration is reused and shared among all my integration tests ?

If not, how can I achieve this ?
