# script/test: run the test suite. Testing is a phase of the Dockerfile
# and this builds that phase alone, on the same terms as script/lint:
# --target because a phase that is not the last stage is built only when
# named, and a new CACHEBUST value because a cached test layer is a test
# that did not run; unlike --no-cache, it keeps Go's build cache.
# --output type=cacheonly writes no image, since nothing uses one.
