Spring Boot provides an annotation @SpringBootTest that we can use in integration tests. You can use the target mocks during the configuration phase as well as in the target test method to replace the real endpoints before performing verifications and assertions, as the following example shows: The following example shows how to use Java Configuration to achieve the same configuration as the preceding example: For this purpose, the aforementioned MockIntegrationContext should be used from the test, as the following example shows: Unlike the Mockito MessageSource mock object, the MockMessageHandler is a regular AbstractMessageProducingHandler extension with a chain API to stub handling for incoming messages. Spring will now read the properties from the application-test.yml file directly, and we can reuse the configuration between any tests that require them. @Test For this demonstration, keep in mind this would be some type of different service youd call to retrieve product data.
