+// Arguments:
+//    feature_description: a short string describing what feature is being
+//        tested. Examples: "usb.GetDevices()", "PaymentRequest()".
+//    test: test created by testharness. Examples: async_test, promise_test.
+//    src: URL where a feature's availability is checked. Examples:
+//        "/permissions-policy/resources/permissions-policy-payment.html",
+//        "/permissions-policy/resources/permissions-policy-usb.html".
+//    expect_feature_available: a callback(data, feature_description) to
+//        verify if a feature is available or unavailable as expected.
+//        The file under the path "src" defines what "data" is sent back via

+//        are run accordingly to test a feature's availability.
+//        Example: expect_feature_available_default(data, feature_description).
+//    feature_name: Optional argument, only provided when testing iframe allow
+//      attribute. "feature_name" is the feature name of a policy controlled
+//      feature (https://w3c.github.io/webappsec-permissions-policy/#features).
+//      See examples at:
+//      https://github.com/w3c/webappsec-permissions-policy/blob/main/features.md
+//    allow_attribute: Optional argument, only used for testing fullscreen or
+//      payment: either "allowfullscreen" or "allowpaymentrequest" is passed.
