We shouldn't be using _PandasNamedTuple here in the call to check because what is happening internally is that pandas is creating a new class of type pandas.core.foo.Pandas, and if you use the name="Foobar" argument, the class is of the type pandas.core.foo.Foobar

But it's a dynamic class, so I think something like this would be appropriate:

for t1 in df.itertuples():
    assert_type(t1, _PandasNamedTuple)
    assert(t1.__class__.__name__ == "Pandas")
    assert(isinstance(t1.Index, int))
    assert(isinstance(t1.col1, int))  
    assert(isinstance(t1.col2, int))
    for k in [0, 1, 2]:
        assert(isinstance(t1[k], int))

And you could add a similar test for having name="Foobar" as the argument, and only the line that checks the name of the class would need to be changed.
