Java 如何为集成测试伪造vaadin会话？

假设我有一个自定义注释

Karibu测试

它有模拟Vaadin会话的方法，支持V8和V10+，甚至支持Kotlin
 玩了一会儿。看起来不错，但尚未成功将其集成到我们的应用程序中。（认为Spring Security在某种程度上进行干扰，但不确定。）将在时机更合适时仔细观察。不过谢谢你。
@RunWith(SpringJUnit4ClassRunner::class)
@SpringBootTest
@WebAppConfiguration
class FooAnnotationIT{

    @Autowired(required = false) //required=false --> empty list instead of exception when none are found
    @Foo
    val foos:List<Any> = mutableListOf()

    @Test
    fun `all beans are present`(){
        assertThat(foos.size).isEqualTo(5)
    }
}

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'blah.blah.blah.FooAnnotationIT': Unsatisfied dependency expressed through field 'foos'
    Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'viewCache': Scope 'vaadin-ui' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton
