Base JUnit 5 class for UI unit testing applications based on Spring Framework. This class provides functionality of the Spring TestContext Framework, in addition to set up a mock Vaadin Spring environment, so that views and components built upon dependency injection and AOP can be correctly be handled during unit testing. Usually when unit testing a UI view it is not needed to bootstrap the whole application. Subclasses can therefore be annotated with @org.springframework.test.context.ContextConfiguration or other Spring Testing annotations to load only required component or to provide mock services implementations.

@ContextConfiguration(classes = ViewTestConfig.class)
class ViewTest extends SpringUIUnitTest {

}
@Configuration
class ViewTestConfig {
    @Bean
    MyService myService() {
        return new my MockMyService();
    }
}
