Testing drain leaks for inspection

My inspector told me to fill the water to test for drain leaks.

I know that I need to plug all openings. But can anyone tell me how to plus the drain connecting to the main stack ? there's no opening there, what fitting should I use ?

Thanks in advance for any help !

There are inflatable balloon like things used to plug the drain lines. You would use 1 at the building cleanout. It is just shoved in place and pumped up with air.
Branch lines can use "dollar" plugs (expandable rubber plug) to seal them. (Remove the p traps from lavs and sinks) Toilet(s) is/are pulled and uses proper sized dollar plug(s).

Good luck...
