jQuery .click() is clicking, but it shouldn´t

while testing my JavaScript I have the following problem:

$('#idOfMyElement').click();

is executed. But I want to verfiy with my test, that is is not executed, because it has the following CSS:

<span style="cursor: not-allowed; pointer-events: none;" id="idOfMyElement"></span>

I debugged it and it is sure, that when the .click() is executed, it has DEFINITELY the mentioned CSS-attributes. In my normal program it works (means that the click doesn´t work), but in my test the click works, even if it shouldn´t.

I have no clou, what might be the problem. Thanks for your help!
