Why automated testing?

Plainly said: it all boils down to saving you a lot of hassle. There are no emotions or time-intensive execution will keep you from (re)running tests. It's just a matter of pushing the button and getting the tests carried out. This is reproducible, fast, and objective.

To clarify, automated tests are the following things:

• Easy to reproduce
• Fast to execute
• Objective in its reporting

If it was as straightforward as that, then why haven't we been doing this in the Dynamics 365 Business Central world all those years? You probably can come up with a relevant number of arguments yourself, of which the most prominent might be: we do not have time for that. Or maybe: who's going to pay for that?
