// Here's the set-up for this test:
// Step 1 (top-frame) Set up listener for "HasAccess" message.
// Step 2 (top-frame) Open channel first-party broadcast.
// Step 3 (top-frame) Embed an iframe that's cross-site with top-frame.
// Step 4 (sub-frame) Try to use storage access API and send first-party broadcast.
// Step 5 (sub-frame) Embed an iframe that's same-origin with top-frame.
// Step 6 (sub-sub-frame) Try to use storage access API and send first-party broadcast.
// Step 7 (sub-sub-frame) Send "HasAccess for BroadcastChannel" message to top-frame.
// Step 8 (top-frame) Receive "HasAccess for BroadcastChannel" message and cleanup.
async_test(t => {
let broadcasts = [];
// Step 1
window.addEventListener("message", t.step_func(e => {
if (e.data.type != "result") {
return;
}
// Step 8
assert_equals(e.data.message, "HasAccess for BroadcastChannel", "Storage Access API should be accessible and return first-party data");
assert_array_equals(broadcasts, ["Same-origin handle access"], "Should have only seen same-origin handle broadcasts");
t.done();
}));
// Step 2
const id = Date.now();
const channel = new BroadcastChannel(id);
channel.onmessage = (event) => {
broadcasts.push(event.data);
};
// Step 3
let iframe = document.createElement("iframe");
document.body.appendChild(iframe);
}, "Verify StorageAccessAPIBeyondCookies for Broadcast Channel");
