Subject: Re: passing data to tests with test/unit

Thanks Brian,

This would work ok if there was only one test method and only 3 types. 
Now let's say that I want to use this test technique multiple times, 
with multiple test methods.  And, the data input is over 100 items. 
Duplicating this structure 100 times doesn't seem tenable.

What I am really looking for is a data-driven test method, such that I 
can use the same test case and pass it different data.  However, for 
test execution and measurement purposes, it is preferable to record 
these as separate tests.
