/* This test is hard to follow so here a quick description of what it is about.
|
|
* We want to test that when BroadcastChannel is used in a bfcached page,
|
|
* this page is fully removed by bfcache.
|
|
*
|
|
* To test it we have 2 pages (testUrl1 and testUrl2).
|
|
* The steps are:
|
|
* - we show testUrl1. When this is shown page1Shown is called.
|
|
* - page1Shown creates a BroadcastChannel object, then it loads testUrl2.
|
|
* - page2Shown is called by testUrl2.
|
|
* - Based on expectedPersisted we use or not the BroadcastChannel object of
|
|
* testUrl1.
|
|
* - Then we call history.back() and testUrl1 will be loaded again.
|
|
* - when page1Shown is called by testUrl1, if BroadcastChannel has been used
|
|
* when testUrl2 was shown, we want event.persisted be false, otherwise
|
|
* true.
