My integration tests take about 10-12 minutes to run and I'd like to look into ways to decrease this. I am using WebApplicationFactory with an xUnit V3 assembly fixture, so it is shared between all tests. I am also using Testcontainers with PostgreSQL and Redis. I tried using the Rider profiler for my unit tests but I just got a bunch of flamegraps in internal BCL methods that I didn't really know how to make sense of. To start with, what strategies can I use to work out where my test methods spend most of their time?
