* Add signposts to performance tests. - Update flow to include support for the migration screen. * If the welcome screen shows, click on the button. * Ensure a clean simulator each run. * Add accessibility identifier for migration screen if required. * Handle walking into the room and back out again. * use iphone 14 pro to match what's used in xcode. * Remove ApplicationTests as duplicated in LoginTests. We measure app startup time in LoginTests as part of the flow - we may as well avoid spending 60s doing only that measurement in ApplicationTests * Sleep 10s, the ui is otherwise showing up in random order. * Revert "Remove ApplicationTests as duplicated in LoginTests." This reverts commit 8670710315bcd0d6c3c3046f534b32b4c728b837. * Update script to parse out correct values from results file. * Allow cancellation of password prompt in any order. * Remove test timeout, performance tests will always take a while. * Adjust parsing further * Remove ApplicationTests. * Move to a more elegant way to wait for something to disappear. * Linting. * Fix unit tests. --------- Co-authored-by: Doug <douglase@element.io> Co-authored-by: Doug <6060466+pixlwave@users.noreply.github.com>
