.. admonition:: Finding data from your production database when running tests?
If your code attempts to access the database when its modules are compiled,
this will occur *before* the test database is set up, with potentially
unexpected results. For example, if you have a database query in
module-level code and a real database exists, production data could pollute
your tests. *It is a bad idea to have such import-time database queries in
your code* anyway - rewrite your code so that it doesn't do this.
