What are “Mnemonics”?
Mnemonics are rhymes or acronyms, these are used to help memorise long, complicated or complex things. Generally it’s easier to memorise a rhythm or acronym and then use that to fill out the information that is associated with that rhyme or acronym. It is used as a memory aid.
In testing, mnemonics can be used as a starting point to work through ideas on what areas might be impacted by a new feature or a change. They help with asking the right questions and help with identifying the areas and functions that need testing. They can help come up with ideas on where you might find “oracles”, which can be used to identify if the application is functioning as designed.
