Integrated vs Functional testing: how to test REST APIs in Grails using Spock
@aruizca shows how to use the REST Client build client to create end-to-end tests for a REST API in a Grails 2 app.
I linked before in this newsletter to a talk titled Testing with Grails 3 by @jeffscottbrown where he describes the same approach for a Grails 3 app. Of course with the few changes imposed by Grails 3 regarding integration tests (e.g. @Integration annotation instead of IntegrationSpec extension).
That it is to say. If you are still in Grails 2 this approach will transition perfectly once you move to Grails 3.

GORM 6 - Spring Container-free
The OCI Grails team announced the release of Grails 3.2 Milestone 2, which includes GORM 6 Milestone 2
They describe the GORM release as the biggest release ever!
There are many new things about GORM 6. For example, I talked in a previous issue about RxGORM. The ability to use GORM without Spring is a huge thing and I think it will increase GORM adoption beyond Grails apps and into other frameworks and apps.
Example of adding Spring Rest Docs to a Grails 3 App
@codeJENNerator shows in this Github repository how to integrate Spring Rest Docs with Asciidoc to generate API rest documentation for a Grails 3 App.
Check out an example of the documentation generated.

Upgrading to Grails 3
Blog post by @WhyPhilip which summarises some of the challenges you will face while migrating from Grails 2 to Grails 3: New Tech, Configuration, IntelliJ, Plugins.
The post is 8 months old. I believe some of the described issues are now solved. Nonetheless, they are good points. Written in June 2016. I will recommend anyone performing a migration to read as many posts as this one as possible. Search the archives of this newsletter, I've linked to a couple of similar posts already. It will save you some valuable time and give you a better understanding about the changes you will face.
With GR8Conf US around the corner I expect many great talks to popup in the coming weeks and fuel this newsletter. I bet Grails 3.2 stable release may come out just ready for the conference. Indeed, a lot GORM 6 stuff is already previewing (more about it in a later link).
