Confluence functional test cases

[Ashish_Jain]

We are in the process of migrating our current Confluence data center edition instance to v7.4. Are there any documented functional test cases that the community uses for testing confluence during migrations. We currently test manually by adding, editing pages, collaborative editing, plugins, and macros testing, etc. but they require a lot of manual efforts. 

Any guidance to automate the test cases which the community and team follow would be appreciated.
