+       This wpt should run on an origin which is different than https://web-platform.test:8444/,
+       from where cross-orign WebBundles are served.
+
+       This test uses the two cross-origin WebBundles:
+
+       1. https://web-platform.test:8444/web-bundle/resources/wbn/cors/cross-origin.wbn,
+          which is served with an Access-Control-Allow-Origin response header.
+       2. http://web-platform.test:8444/web-bundle/resources/wbn/subreource.wbn,
+          which is served *without* an Access-Control-Allow-Origin response header.
+
+      `cross-origin.wbn` includes two subresources:
+       a. `resource.cors.json`, which includes an Access-Control-Allow-Origin response header.
+       b. `resource.no-cors.json`, which doesn't include an Access-Control-Allow-Origin response header.
