You can install PHPUnit via Composer by running the command: composer require --dev phpunit/phpunit. Make sure you have Composer installed.

Can you show me a simple example of a unit test?

Sure! Here's a simple example:

use PHPUnit\Framework\TestCase;

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

This test checks if 1 + 1 equals 2.
