How to run phpunit with different linux user?

@ethelyn 

To run PHPUnit with a different Linux user, you can use the su command to switch to that user before running the PHPUnit command. Here's how you can do it:

1. Open a terminal.
2. Log in as the user you want to run PHPUnit as. You can use the following command: su - [username] Replace [username] with the actual username of the user you want to switch to.
3. You will be prompted to enter the password for that user. Enter the password and press Enter.
4. Navigate to the directory where your project is located.
5. Run PHPUnit as usual using the phpunit command. For example: phpunit

PHPUnit will now be executed with the permissions of the user you switched to.
