1431490 - Can't load prepopulated test DB in XCUITest

Status: RESOLVED FIXED

(Firefox for iOS :: Build & Test, enhancement)

Description

[No-Jun Park [:njpark]]

One can download and save the application data from ios app, and load it next time the app is launched, to prepopulate the app with the data when running xcuitest.  This would enable us to do many things, including performance and endurance test.

But currently browser.db is stored in the shared container folder, so reloading the .xcappdata would only show the last visited page on the browser, and nothing else.  If we can save the db inside the app data (at least for certain test schemes) it would be great.

I believe we have discussed moving the db out of this location. It is there for app extensions to access it and IIRC there is interest in ensuring DB access goes through the main app.

This creates a folder in the source called 'test-fixtures', and test schemes will copy the contents of this folder into the Client app bundle.
Then by adding launch arguments, we can tell the Client.app to load files from its bundle.
In this case, I implemented loading a browser.db that is pre-populated.
The test case is called  `testDatabaseFixture()` and the corresponding test DB is `text-fixtures/testDatabaseFixture-browser.db`.
Note that regardless of what the test database is called, it will always be copied to profile/browser.db, and becomes the BrowserProfile for the running app.

Any test can now have a `text-fixtures/<testname>-browser.db` if needed.

Looks good to me, so should we create a separate bug about creating the db from device/simulator for future use?  Since most of the data is under shared directory, downloading the container of device/simulator won't save bookmarks or history.
