If I understand you correctly I'd write at least two tests. Something like:<br>
<br>
@raises(SomeException)<br>
def test_an_error_is_thrown():<br>
# setup some mock stuff to make the __init__ raise an exception<br>
ClassUnderTest(some mocks or something)<br>
<br></blockquote><div>I overlooked the possibility of using mock, thanks for pointing that out.</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
def test_good_behavior():<br>
# setup some mock stuff in a good way<br>
x = ClassUnderTest(some mocks or something)<br>
# assert some behavior<br>
