SpringBoot test - Cannot load driver class: org.h2.Driver

Question

I have this class in my springBoot app:

@ContextConfiguration(classes={ ApplicationTestConfig.class})
@RunWith(SpringRunner.class)
public class ServiceTest {

    @Autowired
    private RuntimeService runtimeService;

    @Autowired
    private TaskService taskService;

    @Autowired
    private HistoryService historyService;
..
}

my application.properties:

spring.datasource.url=jdbc:h2:mem:testdb;MODE=MySQL;DB_CLOSE_ON_EXIT=FALSE
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driverClassName=org.h2.Driver
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

my pom.xml:

 <dependency>
     <groupId>com.h2database</groupId>
     <artifactId>h2</artifactId>
     <version>1.4.200</version>
     <scope>test</scope>
 </dependency>

but when I run the test I got this error:

Try with this if it may work for you

<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
