Lazy loading for spring integration/component tests

LazyInitializationBeanFactoryPostProcessor.kt

/**
 * Enables lazy initialization of beans in tests, which means that
 * only the beans you're actually using in a test will be initialized/instantiated for you.
 *
 * The main advantage of this approach is that it removes the need to configure
 * properties for beans that you are not even using.
