Automated Spring testing including Vaadin Scopes

Hi all.

Did anyone tried to migrate the integration tests from Vaadin 8 to Vaadin 14?
In Vaadin 8 there was vaadin-spring-ext-test ( extension. We integrated that in Vaadin 8 Application and we got vaadin scopes available in tests so that they can run accordingly.

Now we are migrating to 14 and the tests doesn’t work anymore. vaadin-spring-ext-test is not compatible to Vaadin 14.

So how do we do automated testing with Vaadin 14, Spring (Not Spring Boot)? Is there an alternative to vaadin-spring-ext-test?

Concret Example:
The following service

public class GreetService implements Serializable {

    public String greet(String name) {
        if (name == null || name.isEmpty()) {
            return "Hello anonymous user";
        } else {
            return "Hello " + name;


should be testable with the following code:

@ExtendWith( SpringExtension.class )
public class GreetingTest
	private GreetService greetSvc;
	public void testGreeting()
		Assert.assertEquals( "Hello World", greetSvc.greet( "World" ) );

Thanks a lot for any help.
