HL7 Automation using Ready API
How to automate HL7 protocol using ReadyAPI?
Someone else asked a similar question several months back regarding HL7 messages and I realised I actually did a ReadyAPI! project testing these messages when I worked for the UK's National Health Service (at the time they werent known as HL7 messages despite the fact thats exactly what they were).
Your question is hugely vague however so cant be answered in a single response.
Short answer - its entirely possible to test and automate the testing of these HL7 messages cos thats exactly what I did!
