The RestTemplate class is a Spring class that provides an easy way to communicate with RESTful web services from within an application. It offers several convenience methods for performing HTTP requests and handling HTTP responses, such as getForObject(), postForEntity(), exchange(), etc. It also supports automatic conversion of Java objects to and from JSON or XML using HttpMessageConverter instances.

This is true because the @PropertySource annotation provides a convenient and declarative mechanism for adding a PropertySource to Spring's Environment. A PropertySource is an abstraction for a source of name/value pairs that can be used by the Environment to resolve properties. The @PropertySource annotation can be used to load properties from an external file, such as a .properties or .yml file, and make them available to the application context.

A web slice test is a type of test in Spring Boot that focuses on testing only the web layer of an application, without starting a full server or requiring a real database. To isolate the web layer from other dependencies, such as services or repositories, mocks can be used to simulate their behavior and return predefined responses. To create and inject a mock for an existing bean in the application context, the @MockBean annotation can be used on a field or a parameter in the test class. This annotation will replace any existing bean of the same type with a mock created by Mockito.

A bean definition profile is a named logical grouping of bean definitions that can be activated or deactivated in different environments. For example, we can define different profiles for development, testing, and production environments. Spring provides the @Profile annotation to mark a bean definition or a configuration class as belonging to a specific profile. To activate a profile, we can use the spring.profiles.active property or the ConfigurableEnvironment.setActiveProfiles() method.

The @ActiveProfiles annotation is a class-level annotation that is used in conjunction with the Spring TestContext Framework to declare which profiles should be active when loading an ApplicationContext for an integration test. This annotation can be applied to any class annotated with @ContextConfiguration or a meta-annotation that is composed of @ContextConfiguration.
