+// These tests rely on the User Agent providing an implementation of the
+// FakeSerialService interface which replaces the platform-specific
+// implementation of the Web Serial API with one that can be automated from
+// Javascript for testing purposes.
+//
+// In Chromium-based browsers this implementation is provided by a polyfill
+// in order to reduce the amount of test-only code shipped to users. To enable
+// these tests the browser must be run with these options:
+//
+//   --enable-blink-features=MojoJS,MojoJSTest
