i am using H2 in memory database for testing and my configuration is as follows:
1- SpringTestingConfig: Code:
@Configuration
@ComponentScan(basePackages = "com.myapp.data", excludeFilters = { @Filter(Configuration.class) })
@PropertySource("classpath:/test.properties")
@Profile("test")
public class SpringTestingConfig {
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("org.h2.Driver");
dataSource.setUrl("jdbc:h2:mem:test;MODE=Mysql;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;INIT=CREATE SCHEMA IF NOT EXISTS MYAPP");
dataSource.setUsername("sa");
dataSource.setPassword("");
return dataSource;
}
}
2- MyTestClass: Code:
@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({ WebContextTestExecutionListener.class,
DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class,
TransactionalTestExecutionListener.class })
@ActiveProfiles("test")
@DirtiesContext
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = {
SpringConfig.class, SpringTestingConfig.class,
SpringLocalContainerJPAConfig.class, CustomConfiguration.class })
@PrepareForTest({ FacesContext.class })
@PowerMockIgnore({ "javax.management.*", "javax.xml.parsers.*",
"com.sun.org.apache.xerces.internal.jaxp.*", "ch.qos.logback.*",
"org.slf4j.*" })
public class MyTestClass{
@Test
public void signup(){
this.company = userService.saveCompany(company);
this.user.setCompany(company);
this.user = userService.saveUser(this.user); // gives exception
}
}
3- Save methods: Code:
@Transactional(propagation = Propagation.REQUIRED)
public User saveUser(User user) {
return userRepository.saveAndFlush(user); //JpaRepository
}
@Transactional(propagation = Propagation.REQUIRED)
public Company saveCompany(Company company) {
return companyRepository.saveAndFlush(company); //JpaRepository
}
4- JPA Config Code:
@Configuration
@EnableSpringConfigured
public class SpringJNDIJPAConfig {
protected static final Logger logger = LoggerFactory.getLogger(SpringConfig.class);
protected static final String HIBERNATE_TRANSACTION_JTA_PLATFORM = "hibernate.transaction.jta.platform";

ISSUE: the code in test method works very fine when running the application (local database), but when running it from test (in memory database) it saves company and when trying to save user it gives the exception:
Code:
