This script provides a convenient way to test exercises against a test runner image.

Adapted from Go bin/verify-exercises-in-docker, which was itself adapted from other tracks.

I recently found a different way to solve the clean-up problem of root-owned sub-directories:

docker_args+=( --mount "type=volume,dst=/solution/target" )

Then ${tmpdir}/target never exists, so trap 'rm -rf "${tmpdir}"' EXIT succeeds.

With groovy's current test runner we would have noise

rm: cannot remove 'target': Resource busy

because the test runner has rm -rf target immediately before running the tests.
