This random failure was happening because of the time required to render
and interact with the file picker which sometimes exceeded 2 seconds,
depending on the speed of the machine running the tests.
Converting these tests to use an onlinetext submission and drop the JS
requirement means that they are much less susceptible to runtime issues,
and not susceptible to those caused by JS at all.
This feature had lots of small issues and it made sense to fix it whilst
investigating a query:
* most of the steps do not require JavaScript
* it uses the UI to set an admin setting, for every scenario:
** only 3-4 of the scenarios actually test that setting
** it is very slow to do it his way when we have a generator step we can use
* we create two assignments in the Background, but each test only uses one of them
* we create the assignments in the Background with a generator, but
update them to modify various settings in each Scenario using the UI
when we should just create one assignment for each test and set it up
correctly for that Scenario
Previously, a set of calculated quiz statistics would only 'last' for
15 minutes. Then they would be considered invalid and not used.
Now, computed statistics are kept indefinitely. Instead, when a new
batch of values are computed for a particular set of settings, older numbers
for the same settings are deleted first. Therefore,
question_stats_cleanup_task is no more.
Previously, when users viewed the question bank, if the quiz statistics
had not already been calculated, we would try to compute them there an then.
This could be very, very slow, leading to session lock problems.
Now, we never try to compute the statistics on the fly. Instead, we rely
on the existing \quiz_statistics\task\recalculate scheduled task to do it.
- Only resize if the H5P EmbedCommunicator is defined (otherwise, it was causing a
JS error)
- An unnecessary image has been removed from the greeting-card.h5p fixture package.
That way, the text will always be displayed (even if the iframe is still not
resized). Instead of replacing the original greeting-card-887.h5p file, I've
renamed it to greeting-card.h5p, to remove these ugly and unnecessary numbers
at the end of the file name).
I cherry-picked this branch from master (because the current 401
had some conflicts). In master, quiz has been moved to quiz_settings,
so that's why the behat test start failing. Using the proper name
fixes it.
