Bertrand Dunogier, yes, the PR did not include much more info that could be useful for QA tests though, than the description of this jira itself.
As a matter of fact, we didn't quite understand the purpose of it:
is it to test that we CAN actually replace an existing parameter or to add an arbitrary one, or both? The description seems clear "Cannot override view parameters" ( = can't replace), but it is referred "However it is currently possible to replace an existing one (...)" ( = can replace).
However I did just read your latest comment on the PR, and seems somehow our doubts were justified
And which simplest parameter configuration could one perhaps test this with?
