+# IMPORTANT: Fuzz* test cases should be in a dedicated file, conventionally
+# called `fuzz_test.go`, but that's not a requirement. Otherwise once the file
+# name is changed to have the _test_fuzz.go termination instead of _test.go as
+# required by oss-fuzz, the code won't compile as other Test* test cases might
+# not find some requirements given that they are not in a _test.go file.
