| Currently, doctests cannot be used to demonstrate or test that misconstructions produce a syntax error. I'm not certain, but I believe that case is trappable and veriable. The following is an actual use case for one of the tests I would like to have in test.test_genexps.py: Verify that parenthesis are required in a statement >>> def f(n): ... return i*i for i in xrange(n) ... SyntaxError: invalid syntax | ||

| Logged In: YES user_id=31435 doctest has always been able to handle SyntaxError; e.g., see test_generators.py. You need a "Traceback:" line too. This is explained in detail in the current (CVS) doctest LaTeX docs. For example, this spelling works fine as a doctest: """ >>> def f(n): ... return i*i for i in xrange(n) Traceback (most recent call last): ... SyntaxError: invalid syntax """ You can take out the ellipsis between Traceback and SyntaxError if you like. You can also keep your "extra" sys.PS2 line if you like. |
