Should AAV be installed prior to water testing new DWV system?

I'm adding a bathroom in my house and preparing for my rough-in inspection which will involve plugging the main waste line and filling everything with water to test for leaks. I'm using an air admittance valve (AAV) for the bathroom lav instead of a vent out the roof.

Before I fill the DWV system with water, should I remove the AAV and cap off the opening? Or is it fine to leave the AAV installed for the test? It's unclear to me if the AAV is designed to prevent water from gushing out of it. I'm trying to avoid flooding my house with water! Thanks!
