Question

I am writing some unit tests to ensure that everything is working as supposed in my application and thought it would be an good idea to write a short test script to ensure that the mySQL connection is working as intended.

Is there any query I can run that will always output something sweet that I can verify the connection upon, without having to think about eventual stored data in the mySQL database?

Answer 1

is there any query I can run that will always output something sweet

This should do it

SELECT 'Something sweet'

Edit
If you don’t want something sweet you can always use the built-in functions:

SELECT version()
