<!--
|
|
Test that a self updating service worker can't keep running forever when the
|
|
script changes.
|
|
|
|
- self_update_worker.sjs is a stateful server-side js script that returns a
|
|
SW script with a different version every time it's invoked. (version=1..n)
|
|
- The SW script will trigger an update when it reaches the activating state,
|
|
which, if not for the update delaying mechanism, would result in an iterative
|
|
cycle.
|
|
- We currently delay registration.update() calls originating from SWs not currently
|
|
controlling any clients. The delay is: 0s, 30s, 900s etc, but for the purpose of
|
|
this test, the delay is: 0s, infinite etc.
|
|
- We assert that the SW script never reaches version 3, meaning it will only
|
|
successfully update once.
|
|
- We give the worker reasonable time to self update by repeatedly registering
|
|
and unregistering an empty service worker.
