Whether you are just starting out or are running an established company, it is a good idea to have a strong quality assurance plan in place.

1. Make use of the iNTERFACEWARE utilities

• By making intelligent use of the iNTERFACEWARE tools, setting up a good quality assurance plan should not be an expensive undertaking. The msgtransform and msgdiff tools mean that having a good quality assurance program is quick and easy to set up even if you're a small company.

2. Why is regression testing important?

• Regression testing becomes very important for your quality assurance by the time you have a few dozen customers using HL7. Fortunately you already have the perfect tool for testing your parsing with the msgtransform tool.

3. Keep a sample set of messages

• By keeping a decent sample of messages from each of your customers you can easily set up an automated nightly regression test to ensure that Iguana will parse the HL7 from each flavor in the same way.
