Ask HN: What do you wish you could tell your boss about Testing

Hi! I'm a Software Testing/QA/SDET Manager. What is something about testing you, as a software engineer, want your manager to know, or wish you could say to your boss?

I was a full stack engineer for most of my career. I wished I could impart to my manager how I (and really my whole team) didn't have time to prioritize writing tests. The result was that the tests we did write were rushed and sloppy.
