How to set up codeception testing?

Question

Yii

I have a stupor with codeception. It is not clear whether it was established or not. When the console says

codecept -v
"codecept" is not an internal or external
command, operable program, or batch file.

But it is not clear how to start even testing. In yii2 composer.json, this is what is available

Help to deal with testing or throw to read, relevant. Because I found on the Internet it does not help and it is not clear what is where

Answer 1

I recommend that you spend a small amount of time and watch this video, it seems that everything is clearly chewed in it

Answer 2

I'll leave it here, because I also had a problem with running tests, I was looking for an answer for a long time.
In my case, in the OpenServer console, from the root folder of the project (Basic), run the command
%cd%/vendor/bin/codecept run
