They want those things, sure, but I think it would take multiple weeks of dedicated work for me to set up tests on our primary system that would cover much of anything. Big investment that might enable faster future development is what I find hard to sell. I am already seen as the “automated testing guy” on my (separate) project, and it doesn’t really look like I’m that much faster than anyone else.
What I’ve been meaning to do is start underloading my own sprint items by a day or two and try to set up some test infrastructure in my spare Fridays to show some practical use. But boy is that a hard thing to actually hold myself to.
