What are some best practices for implementing regression tests in a PHP application using PHPUnit?

When implementing regression tests in a PHP application using PHPUnit, it is important to follow best practices to ensure the effectiveness and reliability of the tests. Some best practices include writing specific and isolated tests, using fixtures to set up test data, utilizing data providers for parameterized tests, and regularly updating and maintaining the test suite. 

// Example of implementing regression tests in a PHP application using PHPUnit

use PHPUnit\Framework\TestCase;

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

    public function testSubtraction()
    {
        $result = 2 - 1;
        $this->assertEquals(1, $result);
    }

    // More test methods can be added here
}
