Indeed, py.test parametrization does not work with unittest2.TestCase.<br>
The unittest/unittest2 support of py.test aims at compatibility<br>
and invokes some not-so-easy-to-customize unittest code. I think it'd<br>
be pretty hard to customize unittest2.TestCase to support<br>
parametrization and dynamic setups of test function arguments.<br>

add a new way to run unittest.TestCases such that py.test's parametrized<br>
testing and funcargs work - at the cost of more limited compatibility.<br>
<br>
FWIW i am happy with using assert statements and not have to remember<br>
the assert methods. Do you see a particular shortcoming of using assert?<br>
<br></blockquote><div>No. What I have done in the past is to use assert statements but wrapping them in methods where they get logged when executed. Logging is what i care the most, useful for debugging for me. Currently I need to use unittest TestCase not only for the assert statements but also so the tests can be run without py.test as well. For this reason I realize that I cannot paramterize tests at all. <br>
<br>For now I think will do without the parameterization until we can do without unittest. <br><br>In any case, thanks for the reply. Good weekends!<br>-hans <br></div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
