+This test checks if the side effects for loading Angular packages have changed using <https://github.com/filipesilva/check-side-effects>.
+
+Running `yarn test` will check all ES modules listed in `side-effects.json`.
+
+Running `yarn update` will update any changed side effects.
+
+To add a new ES module to this test, add a new entry in `side-effects.json`.
+
+Usually the ESM and FESM should have the same output, but retained objects that were renamed during the flattening step will leave behind a different name.
