Can't run tests with debug mode in Laravel project

Question

I'm trying to run test with debug mode in my Laravel project. Tests runs but debug mode fails. I'm using: MAMP PRO 6, PHP 7.4.9, Xdebug v2.9.6, PhpStorm.

What can causes this issue. How to fix it?

During debug mode the following messages occurs:

Connection was not established. Cannot start debugger session with
'Xdebug 2.9.6' Validate installation

and next

Connection was not established.
'Xdebug 2.9.6' extension is installed. Check configuration options. Show phpinfo

phpini:

Changing debug port to 9001 in phpstorm config helped for me.
