Basics

Question 1

What are Integration Tests

Answer 1

An integration test is supposed to test whether different modules are bounded correctly and if they work as expected.
The application shall run in ApplicationContext and run tests in it.

Question 2

@SpringBootTest

Answer 2

Spring boot provides @SpringBootTest annotation, which starts the embedded server, creates a web environment and then enables @Test methods to do integration testing. Use its webEnvironment attribute for it. It also creates the ApplicationContext used in the tests.

Question 3

Separate profile

Answer 3

Ideally, we should keep the integration tests separated from the unit tests and should not run along with the unit tests. We can do this by using a different profile to only run the integration tests. A couple of reasons for doing this could be that the integration tests are time-consuming and might need an actual database to execute.
