Grails testing support has been split and relocated to the following repositories:

• grails-gorm-testing-support - grails-data-mapping
• grails-test-support - grails-core
• grails-web-testing-support - grails-gsp
• docs - grails-doc

the gh-pages branch is used to redirect all https://testing.grails.org/ URLs to https://grails.apache.org/docs-legacy-testing/
