What are code autotests and what are they?

Question

Software testing

Goodnight!
What is project (code) auto-testing and how should it all look like for a flash game or a website? Do developers write scripts, for example, in php, where they emulate some kind of sequence of requests to the server?
And if I need to test a multi-user flash game, both a client and a server, how can autotests look like here?

Answer 1

"Developers write scripts, for example, in php, where they emulate some kind of sequence of requests to the server?"
This is usually done by testers. They also know how to write scripts. There are good testing environments where you can develop many automated actions.
Developers and testers work together to write an application in a way that makes it easier to test.

Answer 2

the logic is simple. How do you check that everything is working? Now imagine that you have written a program that does this for you and it gives two results - it works (green) or it doesn't work (red).
Tests can be written at different levels. From the individual modules of your application (the big little pieces) to the entire system (the entire multiplayer game). Next, we add common sense. We must first make sure that each individual component of the system works, and then check how the components in the assembly work.
Next, google.
