Running DocTest on Strings

[notanotheridiot]

Hi,
I have two strings - a docstring containing doctests and a code string
containing code to be tested with those doctests. I've been trying for
a day now to run the test without concatenating the two strings,
adding:

import doctest
doctest.testmod

to the bottom, writing it all to a file and executing it using popen().

There must be some way of doing this without writing to a temporary
file, any ideas?

thanks in advance,

johannes Woolard

Create the concatenated string then exec it?

I know from experience that this approach does not work. When you do
that, the entire module from which it is run turns out to be scanned
for doctests - not only the string being executed by exec. However, I
understand that Johannes found a solution.

Got it, I've blogged about it here:

Basically the trick is to pass the docstring ino the exec environment
as a variable and use the advanced doctest api to get a doctest.
