public @interface SpringBootTest
```
Annotation that can be specified on a test class that runs Spring Boot based tests. Provides the following features over and above the regular Spring TestContext Framework:
- Uses SpringBootContextLoader as the default ContextLoader when no specific @ContextConfiguration(loader=...) is defined.
- Automatically searches for a @SpringBootConfiguration when nested @Configuration is not used, and no explicit classes are specified.
- Allows custom Environment properties to be defined using the properties attribute.
- Provides support for different webEnvironment modes, including the ability to start a fully running web server listening on a defined or random port.
- Registers a TestRestTemplate and/or WebTestClient bean for use in web tests that are using a fully running web server.
