How does Spring Boot Test keep the context across multiple test suites?

I was reading through the guide for using Spring Boot Test and there was a paragraph that got me confused.

“As our profiles get richer, it's tempting to swap every now and then in our integration tests. There are convenient tools to do so, like @ActiveProfiles. However, every time we pull a test with a new profile, a new ApplicationContext gets created.” https://www.baeldung.com/spring-tests

So it assumes that if all tests are run under the same profile, there is only one ApplicationContext created — but how is it possible? I thought that all the objects are recreated for each test suite anyway. Am I missing something?

The official reference says that it's cached.

https://docs.spring.io/spring-framework/docs/current/spring-framework-reference/testing.html#testing-ctx-management

But how does it get loaded into the JUnit runner or Spock one across multiple test suites?

What was missing in my understanding is the fact that all the test suites are run as a part of a single program, so it's easy to cache any objects that are required by all of them, including Spring context.
