( #3333=superdoc: print w/ replies, xml ) Need Help??

I wrote a bunch of tests that depended on a database for holding my data. The tests deleted all the rows from the tables that I was working with and then inserting the test data into the tables. If I did this against the production database I was going to delete the production data as well, that would be bad.

I decided to have a production and a test database. I wanted something that would be easy to include in my test code and would not require a major change in production code. I thought, if I am working with my test modules I make my DB connection code look like this what would I have to do.

use Base::DB::Connect 'test';

The only thing I had to do was include a import subroutine/method. It changed the $database variable from 'Prod' to 'Test' and I was done! I was happy because I did not have to change the code to support 'Test' and 'Production' as separate environments.
