I am not sure that the location of the test is correct. Perhaps remove the nvidia/ subfolder.

In order to put everything to the class body, you need #1862.

@victorusu I simplified and modernized the test. That's the new way! @jjotero Please confirm :-) We are also almost to the point of getting rid completely of __init__() in all cases. By the way, I don't why you were checking also the Pending ECC Mode. Did you have to? I am not checking it here, because I wanted to keep the test simpler.
