Track invocations of methods and functions

I'm looking for the library which allows to track invocation of methods and functions. Think of it as of Mock providing called and call_count properties.

Example of end-result needed:

s = MagicProxyLib()

@s
class MyClass:

    def not_called(self):
        print("This is not called")

    def first_method(self):
        print("First is called")

    def second_method(self):
        print("Second is called")


mc = MyClass()
mc.first_method()
mc.second_method()
mc.second_method()

I can implement such a decorator myself, but do not want reinvent the wheel if there is already some library with similar functionality.

I expect to be able to use this library is a such way

assert not s.called(mc.not_called)
assert s.called(mc.first_method)
assert s.call_count(mc.second_method) == 2

I have checked this answer but profiling/tracing does not quite serve the same purpose as here. Thanks for you package suggestions.

You likely want a profiler - they can collect all this usage statistics. A nice one is shipped along with Python - check: https://docs.python.org/3/library/profile.html
