SpringBoot unit test does not use @EnableAutoConfiguration annotation from Application class

Question

I want to configure a Spring Boot Application so that no DB is used at all. So I have annotated my Application class for excluding JPA autoconfig classes:

@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class Application {

    public static void main(final String... args) {
        run(Application.class, args);
    }
}

This works fine when the service is run standalone

Unfortunately my test classe seems to ignore the annotation, although I use the Application class for my test

@Slf4j
@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class SwaggerJsonExistenceTest {
    ...
}

The test fails with the following error message

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Cannot determine embedded database for tests. If you want an embedded database please put a supported one on the classpath.

Update: There are no DB drivers on the classpath.

org.springframework.boot:spring-boot-starter-data-jpa is used for testing (included via testCompile directive in gradle)

How has the test to be configured so that it does not use db-related autoconfiguration?

Fix: I have removed all jpa starter dependencies (as no DB is needed), so that datasource autoconfig is not done at all.

do you have any database driver on classpath? Which spring boot starters do you use? if you do, remove it. It will stop any db-autoconfiguration magic. — Bartosz Bilicki
@BartoszBilicki I have removed all jpa starter dependencies. it works now, thx. although I still don't know, why excluding the classes does not work for the test... — Gernot

The @SpringBootApplication annotation has an exclude property, which you should use in favor of @EnableAutoConfiguration(exclude = ...) in this case. If you use it, the @SpringBootTest annotated tests should enforce the exclude correctly.
