Overview

@SpringBootTest tells to SpringRunner, which is a JUnit plugin that provides custom Spring-specific testing behavior, to bootstrap the test with Spring Boot capabilities:

• load application.properties
• etc.

@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT)

The @SpringBootTest annotation also has a properties attribute that can be used to specify any additional properties that should be defined in the environment. Properties are now loaded in the exact same way as Spring’s regular @TestPropertySource annotation.
