In this more uncommon scenario, you would have your requirements outside of Jira in some other tool. You use Jira only as a testing repository for creating Tests, Test Sets, Test Plans and Test Executions.
You can use Xray for this, but you will lose the benefits of requirement coverage and traceability.
Architecture
| Number projects | 1 |
|---|---|
| Entities Organization | Test related issues & Defects |
| Team Organization |
Advantages (Pros)
- This separation allows to manage permissions and visibility more effectively
- Keeps your existing requirements and defects project as-is, completely separated from testing related tasks
- Isolates Test Specification
- Keeps sensible data related with bugs and test planning/execution in a different project
Disadvantages (Cons)
- Requires manually synchronizing versions from the requirements project to the other ones
- More projects to manage
- More projects to maintain
- May promote team separation
