Answer: BE

Explanation:

Spring and Spring Boot provide various annotations and utilities to support testing of different layers of the application. To create an ApplicationContext for integration tests, we can use either @SpringBootTest or @SpringJUnitConfig annotations. The former is a specialized annotation that also provides additional features such as auto-configuration, web environment emulation, and test properties management. The latter is a general-purpose annotation that combines @ContextConfiguration and @ExtendWith(SpringExtension.class) annotations.

To perform slice testing, which focuses on testing a specific layer or feature of the application in isolation, we can use annotations such as @WebMvcTest, @DataJpaTest, @RestClientTest, etc. These annotations will only load the relevant beans for the tested slice and mock or stub the other dependencies.
