Bulk testing on your site
You can bulk test all question tests on all variants of all question by using the bulk-test script. This is available from the quetion setting page or from the "adminui" page
[...]/question/type/stack/adminui/index.php
User require capability qtype/stack:usediagnostictools.
Running question tests for questions on other sites (command line)
You can bulk test all question tests on all variants of all question by using the command line bulk-test script contained in the cli directory as follows:
php bulktestall.php
Since you have command line access to the development server you will need to edit this line
$DB->connect('live.database.host.name', 'read_only_user', 'pa55w0rd', 'live_database_name', 'mdl_', $CFG->dboptions);
to specify the remote database. Then run the command line script (perhaps using something like screen to allow this to run in the background while you logout) with the remote option.
php bulktestall.php --remote
Running question tests for questions on other sites (web)
When you upgrade to a new version of STACK, it would be reassuring to know beforehand whether there is any change in behaviour in STACK which will affect your existing questions.
After you have done the upgrade, it is easy to run the question tests in bulk, using the link on the STACK plugin admin screen. However, with a bit of hackery, it is possible to run the code from the new STACK release (with a few modifications) on your development server, but have it open a read-only connection to your live database, in order to load the questions and their corresponding tests.
The following patch is provided as-is. It will probably require tinkering with to work in any given situation.

As an example of the kind of tinkering that might be required, and the time I devised this patch, the new version of STACK had a database change, which had not yet been applied to our live database. Therefore, I had to tweak the question loading code as follows:
