Comment #13 on issue 2252 by [email protected]: activate docstring examples
for symarray()
http://code.google.com/p/sympy/issues/detail?id=2252
So I'm trying to use the try: except: else: approach but....
say the test would be something like this:
... import numpy
... except ImportError:
... pass
... else:
... from sympy import symarray
... symarray('', 3)
...
[Some output]
Doctest will only pass if the output specified in the docstrings is the
same as the one doctest gets, right? Well if numpy is installed the output
would be: "array([_0, _1, _2], dtype=object)", and if numpy isn't installed
you get nothing. The pass isn't bubbled up. But it would work if we have
something like:
... import numpy
... except ImportError:#this function requires numpy to work, fake pass
... print("array([_0, _1, _2], dtype=object)")
... else:
... from sympy import symarray
... symarray('', 3)
...
array([_0, _1, _2], dtype=object)
Isn't this too convoluted?
