Spring Framework Quality Control & Assurance 4

Question 1

Which annotation in Spring Boot Test is used to auto-configure a TestRestTemplate for full integration tests?

Accepted Answer

@SpringBootTest with webEnvironment = RANDOM_PORT

Answer

When @SpringBootTest uses RANDOM_PORT or DEFINED_PORT, Spring Boot auto-configures a TestRestTemplate bean for HTTP client testing.

Question 2

In Spring's testing support, what does ApplicationContext caching mean?

Accepted Answer

The ApplicationContext is reused across tests with the same configuration, reducing startup time

Answer

Spring's TestContext Framework caches the ApplicationContext so tests sharing the same configuration reuse the same context, speeding up test suites.

Question 3

What is the effect of @DirtiesContext on the Spring test ApplicationContext?

Accepted Answer

Clears the context cache so a fresh context is created for subsequent tests

Answer

@DirtiesContext forces Spring to close and recreate the ApplicationContext after the annotated test, useful when a test modifies shared state.

Question 4

Which Spring Boot testing slice would you use to test a REST client that calls an external API, with the HTTP layer mocked?

Accepted Answer

@RestClientTest

Answer

@RestClientTest configures a MockRestServiceServer to intercept and verify HTTP calls made by RestTemplate or RestClient beans.

Question 5

In Spring MVC tests, what does .andExpect(status().isOk()) verify?

Accepted Answer

The HTTP response status code is 200

Answer

status().isOk() is a ResultMatcher that asserts the HTTP response status is 200 OK.
