问题
To be precise depends on what error I have.
If I go with Intellij Maven Install, I get this exception (which is strange because I have this dependency and it should be by default in spring-starter-test if I am not wrong):
Caused by: java.lang.ClassNotFoundException: ch.qos.logback.classic.turbo.TurboFilter
But if I start test directly in problematic test class I get this exception:
o.s.test.context.TestContextManager : Caught exception while allowing TestExecutionListener [org.springframework.boot.test.autoconfigure.SpringBootDependencyInjectionTestExecutionListener@217ed35e] to prepare test instance [mypackage.DataBaseTest@279fedbd]
java.lang.IllegalStateException: Failed to load ApplicationContext

Caused by: java.lang.IllegalArgumentException: Given type must be an interface!
at org.springframework.util.Assert.isTrue(Assert.java:118) ~[spring-core-5.1.4.RELEASE.jar:5.1.4.RELEASE]
For the first exception (Maven->Install) I don't understand, I have that jar with that class.

|---TurboFilter
For the second exception, I cannot understand if @DataJpaTest creates everything. I tried with @SpringBootTest (thought it could be @Service I use with autowired repositories).
I am using Spring Boot 2, jUnit5 with Spring-boot-starter-test with no jUnit4.

Application configuration:
@Configuration
@EnableJms
@EnableJpaRepositories
@PropertySource({"classpath:some.properties"})
public class ApplicationConfig {
...
private Properties getJNDiProperties() {
final Properties jndiProps = new Properties();
jndiProps.setProperty(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
return jndiProps;
}
@Bean
public JndiTemplate jndiTemplate() {
final JndiTemplate jndiTemplate = new JndiTemplate();
jndiTemplate.setEnvironment(getJNDiProperties());
return jndiTemplate;
}
application.properties file:
spring.datasource.jndi-name=jdbc/myDataSource
spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect
spring.jpa.show-sql=false
spring.jpa.properties.hibernate.format_sql=true
spring.jpa.generate-ddl=false
I don't have any test application configuration.
application.properties is empty, I have nothing because I thought @DataJpaTest will create everything for me. Other tests are good but only test class with @DataJpaTest failed with a mentioned exception.
package myPackage;
import myPackage.repository.MyRepository;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.jdbc.core.JdbcTemplate;
import javax.persistence.EntityManager;
import javax.sql.DataSource;
import static org.assertj.core.api.Assertions.assertThat;
@DataJpaTest
public class DataBaseTest {
@Autowired
private DataSource dataSource;
@Autowired
private JdbcTemplate jdbcTemplate;
@Autowired
private EntityManager entityManager;
@Autowired
private MyRepository myRepository;
@Test
public void injectedComponentsAreNotNull(){
assertThat(dataSource).isNotNull();
assertThat(jdbcTemplate).isNotNull();
assertThat(entityManager).isNotNull();
assertThat(myRepository).isNotNull();
}
}
But if I remove @DataJpaTest and add @SpringBootConfiguration and @EnableAutoConfiguration instead all autowired objects are null.
I don't understand why Spring Boot doesn't autowired these objects.
UPDATED
So, with just @DataJpaTest I add @Import(MyRepository.class) but I have the same exceptions.
Maven->Install
Caused by: java.lang.ClassNotFoundException: ch.qos.logback.classic.turbo.TurboFilter
And the class is there!!!
IntelliJ->Run test class
o.s.test.context.TestContextManager : Caught exception while allowing TestExecutionListener [org.springframework.boot.test.autoconfigure.SpringBootDependencyInjectionTestExecutionListener@217ed35e] to prepare test instance [mypackage.DataBaseTest@279fedbd]

UPDATE 2
The reason why I had ClassNotFoundException ch.qos.logback.classic.turbo.Filter was because I had the problem with slf4j and maven surefire so I exclude logback:
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>${maven-surefire-plugin.version}</version>
<configuration>
<classpathDependencyExcludes>
<classpathDependencyExcludes>ch.qos.logback:logback-classic</classpathDependencyExcludes>
</classpathDependencyExcludes>
</configuration>
</plugin>
I removed this configuration and now I have the same exception as I am running directly from IntelliJ.
Caused by: java.lang.IllegalArgumentException: Given type must be an interface!
UPDATE 3
Finally, I make progress. What I needed was @EnableAutoConfiguration. I thought @DataJpaTest will do things for me, but obviously, it has a problem.
Caused by: org.h2.jdbc.JdbcSQLSyntaxErrorException: Schema "MYSCHEMA" not found; SQL statement:
I have Entity like:
@Getter
@Setter
@ToString
@Builder(toBuilder=true)
@AllArgsConstructor
@NoArgsConstructor
@EqualsAndHashCode(of = "logId")
@Entity
@Table(name = "MY_TABLE", schema = "MYSCHEMA", catalog = "")
public class MyEntity {
I need a schema for TEST.
I tried with this, but it didn't help:
@TestPropertySource(properties = "spring.jpa.properties.hibernate.default_schema=PETRA")
回答1:
You don't need @EnableAutoConfiguration for your @DataJpaTest, as the annotation is enabling every required part for testing this slice of the application:
// ... and some more
@BootstrapWith(DataJpaTestContextBootstrapper.class)
@ExtendWith(SpringExtension.class)
@OverrideAutoConfiguration(enabled = false)
@TypeExcludeFilters(DataJpaTypeExcludeFilter.class)
@Transactional
@AutoConfigureCache
@AutoConfigureDataJpa
@AutoConfigureTestDatabase
@AutoConfigureTestEntityManager
@ImportAutoConfiguration
public @interface DataJpaTest {
}
It's important to mention that with @DataJpaTest Spring will use an embedded in-memory database by default:
* By default, tests annotated with {@code @DataJpaTest} are transactional and roll back
* at the end of each test. They also use an embedded in-memory database (replacing any
* explicit or usually auto-configured DataSource). The
* {@link AutoConfigureTestDatabase @AutoConfigureTestDatabase} annotation can be used to
* override these settings.
That's why you see the H2 database output and not Oracle. By default, Spring should use spring.jpa.hibernate.ddl-auto=create-drop to take care that your tables are present.
As you hardcode the schema inside your JPA entity with @Table(name = "MY_TABLE", schema = "MYSCHEMA", catalog = "") you have to ensure that the embedded H2 also uses this schema.
First try to remove schema from the @Table annotation and see if it works. Then you can globally configure your schema inside your application.properties and use @TestPropertySource(properties = "spring.jpa.properties.hibernate.default_schema=PETRA") for your test.
