-# code).
+# script/frontend-test: run the frontend test suite on the host: the
+# unit tests in test/unit/, through the test script in package.json,
+# then the production build, which fails on broken code. make test runs
+# the same tests in the frontend-test stage of Dockerfile, and the image
+# build runs the production build in its frontend-build stage. The tests
+# print a dot each; if any fails, they run again with every test listed,
+# and the script fails even if that run passes. NODE_OPTIONS chooses the
+# reporter because yarn adds its arguments after the test files, where
+# node would take a reporter option for one more file.
