There was a problem hiding this comment.
Note, this was already dead code, prior to these changes.

Note: the self.cpu parameter was only used in a few tests in this file previously. So instead of creating & destroying it around each test, I changed the code to explicitly create a Cpu object only within the test cases that use it.

LGTM. Not much to comment here since it looks like most of the diff is s/self.cpu/cpu/. I'm assuming this will make #1660 easier.

It turns out that most of
tests/native/mockmem.pywas dead code to begin with. Additionally, usingtypeguardduring testing (see #1584), it is revealed that the use oftests.native.mockmem.Memoryturns some type hints elsewhere into lies (since the mocked version isn't a subclass ofMemory).The simplest fix: massage the single file that uses
tests.native.mockmem.Memory, and then delete that whole file.
