[Pyunit-interest] Unit testing constructors

[Sean A. <ze...@wo...>]

Hello, sorry if this has been covered before

Currently, I am trying to implement a test suite for some objects.
The objects need to do bounds checking based on arguments to their
__init__() ctor. If the object is given initialization parameters that
are out of bounds, an Exception must be thrown.

 So far, So good.

I am having a great deal of difficulty trying to get a test case to work
that does something like

(pseudo code)
...
self.assertRaise(Exception, (attempt to create the object), (args))
...
which basically tells me I have to supply an instance of the object I'm
trying to create as first argument, which is not really possible under
these conditions. The code works well in interactive testing, it's just
how to write the unit test

Any ideas? =20
