Transactional (mybatis-cdi: org.mybatis.cdi.Transactional) annotation with rollbackOnly=true not rollbacking transactions inside a Weld / JUnit 5 test

[danielemaddaluno]

I'm not sure it's an issue of the Transactional annotation, it could be some missing configuration.

I have described the issue in detail on stackoverflow.

I'm pasting a copy here:

I expect this class UserMapperTest.java to run the test rollbacking the transaction (in this case for a simple insert, where the field email is unique, but the core of the problem is about the rollbacking):

import jakarta.inject.Inject;
import org.jboss.weld.junit5.WeldInitiator;
import org.jboss.weld.junit5.WeldJunit5Extension;
import org.jboss.weld.junit5.WeldSetup;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.MethodOrderer;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.TestMethodOrder;
import org.junit.jupiter.api.extension.ExtendWith;
import org.mybatis.cdi.Transactional;
import java.math.BigInteger;

@ExtendWith(WeldJunit5Extension.class)
@TestMethodOrder(MethodOrderer.MethodName.class)
@Transactional(rollbackOnly = true)
public class UserMapperTest {
	@WeldSetup
	WeldInitiator weldInitiator = WeldInitiator.of(WeldInitiator.createWeld().enableDiscovery());

	@Inject
	@TestSessionFactory
	public UserMapper userMapper;

	@Test
	public void t1_insert_user() throws Exception {
		User u = userMapper.selectUserFromId(BigInteger.ONE);
		u.setId(null);
		u.setEmail(u.getEmail() + "2");
		userMapper.insertUser(u);
		Assertions.assertNotNull(u);
		Assertions.assertNotNull(u.getId());
	}
}

The main pom.xml dependencies useful for this test are:

<!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api -->
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter</artifactId>
    <version>${junit.version}</version>
    <scope>test</scope>

    <groupId>jakarta.platform</groupId>
    <artifactId>jakarta.jakartaee-api</artifactId>
    <version>${jakartaee-api.version}</version>
    <scope>provided</scope>
</dependency>

with these versions:

<junit.version>5.11.0-M2</junit.version>
<weld.junit5.version>4.0.3.Final</weld.junit5.version>
<weld-se.version>6.0.0.Beta4</weld-se.version>
<jakartaee-api.version>11.0.0-M4</jakartaee-api.version>

My bean.xml is this:

<?xml version="1.0"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
       bean-discovery-mode="all">
   <interceptors>
      <class>org.mybatis.cdi.LocalTransactionInterceptor</class>
   </interceptors>
</beans>

This is the TestSessionFactory annotation:

import static java.lang.annotation.ElementType.FIELD;
import static java.lang.annotation.ElementType.METHOD;
import static java.lang.annotation.ElementType.PARAMETER;
import static java.lang.annotation.ElementType.TYPE;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;
import jakarta.inject.Qualifier;

@Qualifier
@Retention(RUNTIME)
@Target({ TYPE, METHOD, FIELD, PARAMETER })
public @interface TestSessionFactory {
}

And this is the SqlSessionFactoryProviderTest test implementation of the SqlSessionFactoryProvider:

import jakarta.enterprise.context.ApplicationScoped;
import jakarta.enterprise.inject.Produces;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.cdi.SessionFactoryProvider;

public class SqlSessionFactoryProviderTest implements SqlSessionFactoryProvider {
	@Override
	@TestSessionFactory
    @Produces
    @ApplicationScoped
    @SessionFactoryProvider
    public SqlSessionFactory produceFactory() {
        return ConnectionFactory.getSqlSessionFactory();
    }
}

I used to use a similar code with javax and junit 4 and worked fine. I'm trying to upgrade to jakarta and junit 5. It's possible that I'm missing something on the WeldInitiator? The userMapper is injected correctly and the query runs correctly, simply the transaction is not rollbacked.
