[IronPython] pytest results in unsupported PythonDictionary system error

[Piotr Nestorow]

Hi

This is for IronPython 2.7
Pytest 2.0.3 installed in site-packages

Running a test with pytest results in the following system error:
SystemError: Unsupported param dictionary type: IronPython.Runtime.PythonDictionary

Any ideas what the problem is?

----------------------------------------------
Here is the example and the error:

class TestBasic:
    def test_01(self):
        for n in (2, 4, 6, 8, 10):
            yield self.n_greater_than_zero, n
        
    def n_greater_than_zero(self, n):
        assert n > 0
        
if __name__ == '__main__':
    import pytest
    pytest.main()

C:\IronPython\ipy.exe .\test_001_dd.py
Traceback (most recent call last):
