1748664 - Add test case for clearing CORS preflight cache between private browsing sessions

Status: RESOLVED FIXED

Description

[Manuel Bucher [:manuel]]

Follow up on Bug 1738150.

Opening a follow up, because it is a rather big task. I made that the cache is cleared manually by opening the test testing/web-platform/tests/cors/preflight-cache via ./mach test testing/web-platform/tests/cors/preflight-cache.htm in the private browsing tab and adding print statement at the relevant places.

Automatically executing that test is a bit harder, thats why I opened this follow up bug. Additional information: https://phabricator.services.mozilla.com/D133196#4379356

• toolkit/components/cleardata/tests/browser/browser_preflight_cache.js

I'll probably have to figure out how to execute the web-platform test in the private browsing window and check that the cache gets cleared when closing the private browsing window.

I'll probably have to figure out how to execute the web-platform test in the private browsing window and check that the cache gets cleared when closing the private browsing window.

I think it's not that complicated.
The test steps in my mind are:

1. Create a private window (await BrowserTestUtils.openNewBrowserWindow({ private: true });).
2. Test if the CORS cache works with the private window. This function seems to do the trick.
3. Close the private window.
4. Test if CORS cache from the private window is cleared.

Maybe add a new task in toolkit/components/cleardata/tests/browser/browser_preflight_cache.js is easier than creating a new test file.
