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 to what I investigated, the idiomatic way to write unit tests in racket is to write a test module inside the implementation file, and not have a separate file for them. The problem is that I have multiple different implementations of the same specification that share the same unit tests, so I need to import all the implementations in a separate file and run the unit tests there.
So I end up with just a few unit test files, and a lot of racket files that do not contain unit tests, but raco test ends up scanning everything anyway.
I'm looking for a way to use raco test to only run files that have a specific pattern in the name. Like *.test.rkt, *.spec.rkt, test-*.rkt, or similar (like in jest for js or pytest for python).
Is this possible?
I looked into test-include-paths in info.rkt files, but it seems to be for files that are not racket files, and not for whitelisting which files to run.
If you're using bash, zsh, or ksh93 as your shell, you can use a recursive glob to find all the matching files:
raco test **/*.test.rkt
(bash might need a shopt -s globstar first)
or any Unix-y system:
find . -name "*.test.rkt" -exec raco test \{\} +
