PHPUnit: How do I create a function to be called once for all the tests in a class?

Question

I have a PHPUnit test case class (consisting of some test functions). I would like to write a oneTimeSetUp() function to be called once for all my tests in the clas

Expanding on accepted answer:

None of the setUpBeforeClass(), tearDownAfterClass(), @beforeClass, @afterClass runs in the object context (static methods). You can work around that restriction by guarding any @before code with a static property instead, like so:

class MyTest extends PHPUnit\Framework\TestCase
{
    private static $ready = false;

    /**
     * @before
     */
    protected function firstSetUp()
    {
        if (static::$ready))
            return;

        /* your one time setUp here */

        static::$ready = true;
    }
}

It can't be used for @after, however, because there's no way of saying when the last test was called.
