How do I set up PHPUnit for my PHP project?

To set up PHPUnit, you need to install it via Composer. Run composer require --dev phpunit/phpunit in your project directory.

What configuration do I need for PHPUnit?

You should create a phpunit.xml file in your project root to configure PHPUnit settings like test directories and bootstrap files.

Can you show me an example of a simple test?

Sure! Here's a basic test example:

use PHPUnit\Framework\TestCase;

class ExampleTest extends TestCase {
    public function testAddition() {
        $this->assertEquals(2, 1 + 1);
    }
}

How do I run the tests after setting everything up?

You can run your tests by executing vendor/bin/phpunit in your terminal. It will automatically find and run your tests.
