Add data test annotations for datastore, firestore and spanner

[eddumelendez]

Is your feature request related to a problem? Please describe.
Make easy to slice test using datastore, firestoee and spanner

Describe the solution you'd like
Looking into testing-code-that-uses-cloud-spanner I think the project can provide the infrastructure with @DataSpannerTest annotation. There are similar annotation for neo4j, jdbc, jpa and so on in the spring-boot project

See this draft

Describe alternatives you've considered

Additional context

The old docs page does not exist anymore, but do you mean actual emulator startup and the separate gcloud configuration?

It continues to be unclear to me that Spring Cloud GCP is the right layer for those improvements.

[eddumelendez]

I mean having annotations to be used for slice tests in order to automatically load autoconfiguration for data repositories such as datastore, firestore and spanner

This is what is required right now in order to achieve it.

See https://docs.spring.io/spring-boot/docs/1.5.2.RELEASE/reference/html/boot-features-testing.html#boot-features-testing-spring-boot-applications-testing-autoconfigured-jpa-test

Hi @eddumelendez as your PR is outdated, could you submit a new PR for your proposal?

[eddumelendez]

Sure! I think I can do it in the next couple of weeks.

First, would like to know if

• new module is ok?
• tests should use testcontainers gcloud module?
• should I submitted the one in the out-to-date PR first and then the rest of them?

Cheers

@eddumelendez After some discussion, we are going to add this to 2023 planning. Sorry for derailing your contribution the second time for largely the same reason...

[eddumelendez]

thanks for let me know about it! For sure will be still interested to make the contribution next year. So, just let me know so we can discuss first, then agree and make it happen :)
