According to the Billing page of my Azure DevOps I am currently using the Basic account because I am giving the possibility to start a free trial of Basic + Test Plans
But Somehow I am able to create Test Plans and run tests, see the report etc. Is this usual that Basic users can access this section? If yes why would we need to pay for Basic+Test Plans variation?
Basic Users can execute UnitTest using Test Plans service of Azure DevOps for free but for certain cases there is the Basic+Test Plans account needed. What is included in the Basic account and what has to be additionally purchased is listed HERE
