1858696 - Create a marionette test to verify that the expected strings exists in regular browsing mode for both IndexedDB and CacheAPI

Status: RESOLVED FIXED

(Core :: Storage: Quota Manager, task, P3)

Description

[Harveer Singh]

As part of delivering Private Browsing mode for IndexedDB and CacheAPI, we create marionette tests to ensure that on-disk storage is getting encrypted. With marionette, we could analyze filesystem directly to check the sqlite db files, response (cacheAPI) and blob files (IndexedDB) do not contain the original stored strings as they should have been encrypted away.

For IndexedDB, we make sure that original value from key/value pair doesn't occur in the blob file because we assume that values are stored raw in regular mode for indexedDB. We tested this manually but it's better to assert this assumption in test logic as this could change in the future and in that case, our test might not be able to detect encryption regression in that case.

For CacheAPI, we rely on the assumption that response bodies contains magic string 'sNaPpY' as all response bodies gets compressed. So, for PBM testing we ensure that we don't match with 'sNaPpY' in response bodies as they should have been encrypted away. So, similar to IDB, we want to test this assumption.

So, basically we would like to test on-disk contents of IndexedDB and CacheAPI, both sqlite db and their external files (blobs and response bodies respectively)

It doesn't have to be a new test, the existing test for private browsing can be used for that or there would be a common file with common helper functions and then two separate tests for regular and private browsing.
