"46.3.12 Auto-configured Data JPA Tests" read to me that it all works with zero config. However, I received the following error message in my try. Failed to replace DataSource with an embedded database for tests. If you want an embedded database please put a supported one on the classpath or tune the replace attribute of @AutoConfigureTestDatabase. I added h2 to my pom.xml and it worked. The same issue was indicated in this stack overflow QA. https://stackoverflow.com/questions/40659912/spring-boot-starter-test-cannot-run-database-integration-test So, I suggest clarifying in the docs that you need to add an embedded in-memory database for this to work.

You've edited your first comment that quoted the error message we produce
I think that error message is quite explicit on its own. I agree the doc could be a bit more explicit that it does so if it's on the classpath, this is not a requirement at all actually. I've rephrased that in 680ac85 Thanks for the PR, in any case! |

Docs "46.3.12 Auto-configured Data JPA Tests" doesn't specify the necessity to configure an in-memory database. It reads as if everything "just" works.
https://docs.spring.io/spring-boot/docs/2.1.4.RELEASE/reference/htmlsingle/#boot-features-testing-spring-boot-applications-testing-autoconfigured-jpa-test
As consequence, I experienced the same issue as indicated in this stack overflow QA.

So, I suggest clarifying that you need to add an embedded in-memory database for setup.
