Testing Spring Boot Applications

" summary

Starts with a slow full integration test hitting MySQL and a WireMock endpoint, then shows concrete moves to faster, clearer tests: use Spring Boot 1.4’s TestRestTemplate with random port, replace real DB with an in‑memory one via @DataJpaTest and TestEntityManager, stub REST calls with MockRestServiceServer and verify 404 handling, swap real services for Mockito mocks with @MockBean, and use JacksonTester/AssertJ for JSON checks. Examples run and pass, and each change measurably speeds tests and narrows surface under test.
