Assuming you are asking about the unittest module...No, not unless you
do something specific in the unit test, e.g. testing on a large data
set would take more memory.

Unittest just runs the code you tell it to and looks at the result. It
doesn't instrument the code in any way. You do have to load the actual
unittest module but I don't think it has any great memory

Are you seeing this behaviour or just asking about it?
