All the more reason not to be on the digest version. But you should have

What am I missing? The biggest problem is that no one is explaining the

See my other reply and check out the references to programming by

Here at the Library, we use unit test to test the cases that have many
known inputs. For example, some of the data could come in "foo bar baz",
and some others could come in as "foo, bar, baz", and others coul

Well done, thats a good idea.
I am having trouble finding resources that explain how to write effective tests.
Thee are whole books on the subject of testing.
Hi,
I am trying to learn a bit of test-driven programming using unittests and
