instead of silencing the mypy errors can you make the signatures of assert_series_equal and assert_frame_equal compatible between BaseDecimal and BaseExtensionTests.

make the methods in BaseDecimal staticmethods and define the methods in BaseExtensionTests to be compatibile using *args and **kwargs, i.e.

    @staticmethod
    def assert_series_equal(left, right, *args, **kwargs):
        tm.assert_series_equal(left, right, *args, **kwargs)

    @staticmethod
    def assert_frame_equal(left, right, *args, **kwargs):
        tm.assert_frame_equal(left, right, *args, **kwargs)

tried putting staticmethod, BaseExtensionTests methods takes (left,right, some arguments) but BaseDecimal takes (left,right,*args,**kwargs) it is still showing incompatible by mypy, didn't find anything to solve this. I need to study more to solve this.

I think #28994 has the same issue. What error are you getting after trying what @simonjayhawkins suggested?

yes we have two modules that are reporting mypy errors due to the same root issue.
