The word 'diagnostic' is often used when talking about identifying or figuring out what is wrong or causing a problem. It is frequently used in medical settings where doctors are trying to diagnose a patient's illness or condition. It can also be used in other areas such as technology or education, where people are trying to figure out what's going wrong or what needs to be improved. So if someone says they are doing a diagnostic test, it means they are trying to figure out what the problem is.
