What are some best practices for conducting unit testing in PHP?

Best practices for conducting unit testing in PHP include writing tests that are isolated, meaning they do not depend on external resources or other tests, using a testing framework like PHPUnit, following the AAA (Arrange, Act, Assert) pattern in your test methods, and ensuring your tests are easy to read and maintain. 

// Example of a unit test using PHPUnit
use PHPUnit\Framework\TestCase;

class MyTest extends TestCase {
    public function testAddition() {
        $result = 1 + 2;
        $this->assertEquals(3, $result);
    }
}
