Thanks @dvingo. Yes, I guess that the order of evaluation in tests is not predictable as it is when you are running a “regular” Shadow-CLJS app. I’m using Shadow-CLJS’ test runner, so compiled and run through the browser (not REPL). I’ve given up on getting instrumentation to work there - I don’t think it is as important though since I’m not running generative tests. It serves a purpose in development though so I get feedback if my functions don’t work in the semi-real world.
