Inject common attribute from spring configuration file to every test class - spring

Question

I have small clarification regarding the spring injection. I'm writing the test for services. Every Test class has a common attribute called "tenantId". Can I inject that attribute through spring configuration file.I don't want to add every test class to the spring configuration file, Is there a way to that?
#ContextConfiguration(locations = {"classpath*:applicationContext-service-test.xml"})
public class ApplicationServiceTest extends AbstractTestNGSpringContextTests {
#Autowired
TenantBasedSessionFactory tenantBasedSessionFactory;
#Autowired
private ApplicationService applicationService;
private String tenantId = "tenantId"; // I want this to inject from applicationContext-service-test.xml
private Session session;
}
Spring configuration file.

You can create a common superclass for all your tests to inject there your tenantId. With this, you will only have to inject only once and tenandId will be available to all your desired classes.
