Tbh, skipping the test patch can lead to more interesting results. Sometimes the unexpected reactions give the wood unique character. Embrace the surprises instead of trying to control everything.
Test patches save so much time in the long run (even if surprises can be fun sometimes). I'd rather know what I'm getting into before committing to a whole project.
My first big project I skipped the test patch on a pine table. The stain turned this weird greenish gray on the filler spots. I had to sand the whole top down again, which added like two extra days of work. I feel that pain of learning the hard way.
