Where can I find an online system for recording test cases with certain functionality?

Question

Software testing

Required functionality:
1. Creation of test cases
2. Combination of test cases into test suites
3. Pleasant UI
The structure of the system should be based on test cases that can be included in various test suites by means of links to them.
Of, if I may say so, practical examples, I found only this article . Without a description, some that I managed to try do not meet the stated requirements.

Answer 1

Microsoft Test Manager. Ability to bind to TFS. Beautiful, comfortable.
