B. If an embedded database is on the classpath, it will be used to configure a DataSource by default.

This is true because the @DataJpaTest annotation enables auto-configuration of an embedded database if one is available on the classpath, such as H2, HSQLDB, or Derby. This allows the test to run with a temporary and isolated database that can be configured with test data.

D. It auto-configures a TestEntityManager bean.

This is true because the @DataJpaTest annotation provides a TestEntityManager bean that can be used to perform common JPA operations in the test. The TestEntityManager is an alternative to the standard EntityManager that provides some convenience methods and exception translation.

This is true because the default scope of a bean in Spring is singleton, which means that only one instance of the bean will be created and shared by the entire application context. The @Bean annotation on the accountRepository() method indicates that this method will return a bean that will be managed by Spring. However, this method will not be called every time the bean is needed, but only once when the bean is first created. Therefore, only one AccountRepository bean will be instantiated and injected into the TransferService and AccountService beans.

A. @Configuration This annotation indicates that the class has @Bean definition methods and may be processed by the Spring container to generate bean definitions and service requests for those beans at runtime. B. @ComponentScan This annotation configures component scanning directives for use with @Configuration classes. Provides support parallel with Spring XML's context:component-scan element.
