How can the Run Configuration be set up in PHPStorm to ensure that PHPUnit tests are executed correctly without encountering exit code 255?

To ensure that PHPUnit tests are executed correctly in PHPStorm without encountering exit code 255, you need to adjust the Run/Debug Configuration settings. This can be done by setting the "Test Runner" option to "Path to phpunit.phar" and specifying the path to the PHPUnit executable. Additionally, make sure that the "Use alternative configuration file" option is unchecked to prevent conflicts with the default PHPUnit configuration.

// Example of how to set up Run Configuration in PHPStorm for PHPUnit tests
// 1. Go to Run -> Edit Configurations
// 2. Add a new PHPUnit configuration
// 3. Set the "Test Runner" option to "Path to phpunit.phar"
// 4. Specify the path to the PHPUnit executable
// 5. Ensure that the "Use alternative configuration file" option is unchecked

// Sample code snippet for PHPUnit test configuration in PHPStorm
// Path to phpunit.phar is set to /path/to/phpunit.phar
// Path to the PHPUnit executable is set to /path/to/phpunit
