How do I set up and tear down tests in PHPUnit?

In PHPUnit, you can use the setUp() method to initialize resources before each test and tearDown() to clean up afterward.

Can you give me an example of using setUp and tearDown?

Sure! Here's a simple example:

protected function setUp(): void {
    $this->db = new DatabaseConnection();
}

protected function tearDown(): void {
    $this->db->close();
}

This initializes a database connection before each test and closes it afterward.

What if I need to set up resources only once for all tests?

In that case, you can use the setUpBeforeClass() method for one-time setup and tearDownAfterClass() for cleanup after all tests.

Is there a way to skip certain tests?

Yes, you can use the @skip annotation in your test methods to skip them during execution.
