+These tests all follow the same format, calling the `run_test` function from
+`resources/accept_ch_test.js`. This function does the following:
+
+ * checks to make sure no client-hint preferences are saved for a particular origin
+ * loading a page with the response header `Accept-CH: device-memory` via a
+ particular method:
+ * Navigation (via window.open)
+ * Subresource (via fetch)
+ * iframe (added via js)
+ * Navigates to another page to check if the device-memory client hint was sent
+ with the next request
+
+Each test is in a separate file to ensure that the browser and it's state is
+properly reset between each test.
