mysql for junit testing in spring - mysql

Question

Is there any way to use MySQL for JUnit testing with Spring?
I ask this because I have a lot of store procedures in MYSQL and I have noticed that H2 is not working with SPs.
Edit:
Right now my configuration for src/main looks like:
#ComponentScan
#EnableAutoConfiguration
#EnableJpaRepositories
public class Application {
public static void main(String[] args) {
ConfigurableApplicationContext applicationContext = SpringApplication.run(Application.class, args);
}
}
spring.datasource.url=jdbc:mysql://localhost/mydb
spring.datasource.username=user
spring.datasource.password=pw
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
Spring works fine with this configuration. It reads the application.properties, sees the spring.datasource.* and knows that I have set a datasource.
Everything is fine here.
Now, in tests I use something like:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = {Application.class})
#Transactional
public class TxServiceTest {
}
This is not going to run the tests against MySQL database. It will run the tests with H2 database. I need to use MySQL for testing because I am using many stored procedures.
I have tried many other combinations but none of them works. What am I missing here?
Possible fix:
I somehow found a way to make it work. I let the main project unchanged and inside my test project I added a new class:
#Configuration
public class PersistenceContext {
#Bean
public DataSource dataSource() {
org.apache.tomcat.jdbc.pool.DataSource dataSource = new org.apache.tomcat.jdbc.pool.DataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost/mydb?noAccessToProcedureBodies=true");
dataSource.setUsername("xx");
dataSource.setPassword("yy");
return dataSource;
}
}
I don't like this solution too much but it is working.

Sounds like Integration Test. First, make sure that your database is always up-to-date in order to avoid restores and work in common errors. You can use liquibase or flyway to manage deltas. Also, make sure that after execution of the tests the state of the database has not been altered. I mean if you have a table without data at the beginning, after the execution of your test this table must not have data. You can use dbunit or spring-dbunit which is an extension of dbunit for spring to manage this.
In order to use a local mysql database you can use this plugin http://mysql.jcabi.com/
EDIT 01
Replace your h2 dataSource bean:
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/demo" />
<property name="username" value="root" />
<property name="password" value="root" />
</bean>
