Existing logic:
- Iterate all connected outputs
- Check bigjoiner capability (We need to tweak this logic: to force the
bigjoiner & check the capability)
- Add the output to data if it is a bigjoiner capable
- Run the test using available outputs in data
By tweaking the above logic, we can re-use the existing functions to
test the force-bigjoiner.
Please let me know if you need more information.
