Hope now you have an Idea about the PHPUnit and Unit testing.

Today I am going to share the few commands with which you can execute the Unit Testing.
But ,
NOTE : The Magento_Developer module must be enabled.
1. If you want to Execute all the Magento test cases, then use the below command.

php vendor/bin/phpunit -c dev/tests/unit/phpunit.xml.dist vendor/magento/

OR

php bin/magento dev:tests:run.

NOTE : But the above commands takes too much time.

So We need some thing which is faster , so the solution is execute the Unit Tests module wise, so below is a command that can help you with.
2. If you want to Execute the Unit tests with specific Module :  Ex :- magento-catalog .

php vendor/bin/phpunit -c dev/tests/unit/phpunit.xml.dist vendor/magento/module-catalog/Test/Unit/

Magento 2 Uses PHPUnit Package to run Unit Tests .
Basically PHPUnit automation testing framework has been included as a Dependency in Magento 2’s composer.json file.
