12 raco test: Run tests

The raco test command requires and runs the test submodule (if any) associated with each path given on the command line. When a path refers to a directory, the tool recursively discovers all files that end in ".rkt" within the directory and runs their test submodules.

The raco test command accepts a few flags:

• -s ‹name› or --submodule ‹name› — Requires the submodule ‹name› rather than test.

• -r or --run-if-absent — Requires the top-level module of a file if the relevant submodule is not present. This is the default mode.

• -x or --no-run-if-absent — Ignores a file if the relevant submodule is not present.
