[issue25000] _mock_call does not properly grab args and kwargs

[Michael Foord]

Michael Foord added the comment:

This is actually the specified and documented behaviour of mock when it is passed mutable arguments. Deep copying arguments on calls is rife with potential problems (not everything can be copied and it breaks comparison by identity). The documentation suggests ways around this:
