I use rackunit like this in my code (run-tests (test-suite "suite-name" (test-case "case name" ... )) I'm trying to practice TDD. When an assertion fails, I'm able to see which assertion failed. But in case of an error, unfortunately…

Is there a way to limit or whitelist which files the command "raco test" should execute, based on file names or file extensions?

I'm writing unit tests using rackunit and running them using raco through the command raco test ., which recursively finds all racket files and executes them, including files that do not contain unit tests at all. It just runs everything. According…
