Write tests for POM

If there are tests, I've not seen or heard of them.

The POS tests are probably a good starting point. I think we should, at the very least, test the following:

• As an administrator, I can add single products to a purchase order.
• As an administrator, I can add multiple products to a purchase order.
• As an administrator, I can remove a product from a purchase order.
• As an administrator, I can define a lot field and the incremental field widget will convert required units using stepping.
• As an administrator, I can create an email with a PDF attached.

Nice to have tests would be:

• Comprehensive Entity creation / update / delete tests.
• Comprehensive tests that check the filters on various list admin interfaces
• Comprehensive tests that confirm the notes/logging don't miss events.
• Comprehensive tests that check that the configuration options display expected options (that none of the content types are missing from a drop down, for instance).

Ultimately, I want to see at least one test committed to the repo with issues opened for any remaining tests tagged as "low hanging fruit."

You might consider using a non-real email.
