Office 365 Migration: Test Cases - OneDrive for Business

Dear Community,

I hope you are well even during the actual situation.

We are planning test cases for the Office 365 applications for our migration. 

Do we have dedicated test cases or a list of tests for OneDrive, which are already defined? 

We would like to combine automated tests with manual tests. And especially for the manual tests, we would like to have a set of functionality test cases which we could test with a focus group. 

Thanks for your help!
