"Test plugs" don't have to be glued on or cut off and discarded
afterwards. My ISP is slow tonight and not returning images, but I
remember using a type with a garden hose fitting to fill the newly
installed drain plumbing until water ran out the roof stack, to check
for leaks before installing the sinks and toilets.

I have (literally) a shelf-full of them. But all mine are for
"scheduled" (SDR) pipe. I don't even know if they make them to fit
the thinwalled sewer drain pipe. I'll check. but since I need only
make one test, and because I can selectively save at lease one of the
caps by leaving it on the piece... It won't cost me more than a
couple of bucks.

They do make bushings to use standard fittings on that thin wall drain pipe
