Hello, I seem to get problems when running the question tests of from STACK version 2018080600 (that's the version ID from the question test page) in STACK version 2020061000 (this was updated in the course of switching from Moodle 3.8 to Moodle 3.9).
I have test cases with partially empty inputs, with expected score empty and answer note set to NULL. This happens if there are more answer variants for some inputs than for others to test.
In 2018080600 this worked (tests passed)
In 2020061000 such tests fail.
For example, the following test seems to have returned answer note NULL and now returns False on empty input.
ATAlgEquiv(EMPTYANSWER, true) = [0, "ATAlgEquiv_SA_not_logic."];
It seems that handling of empty answer is test-dependent now. This requires attention in question tests for inputs where I actually don't intend to test anything.
Is there a way to de-activate the test for particular inputs in a question test?
