After analyzing test_request.html it became clear that it relied on two false assumptions: 1. It assumed that a service worker is notified that it's being installed before any client can interact with it. 2. It assumed that a service worker will always be installed upon registration, if it was unregistered before. The first assumption is not backed by the spec; it seems that the opposite behavior is the correct one (https://github.com/w3c/ServiceWorker/issues/1347). The second assumption ignores the possibility of resurrection, where a service worker is re- registered before getting uninstalled. This commit addresses both problems by not relying on the installation phase, instead passing the script URL as a search parameter and loading it at service worker script evaluation time. It then runs the test function in response to a message from the client. Differential Revision: https://phabricator.services.mozilla.com/D3879 --HG-- extra : moz-landing-system : lando
