Evoking all possible test failure modes in PHPUnit

When you're writing your own PHPUnit test listener, you need a test case that evokes all the different PHPUnit test states. Here's you go:

<?php
class EvokesTest extends \PHPUnit_Framework_TestCase
{
    public function test_pass()
    {
    }

    public function test_fail()
    {
        $this->fail(__FUNCTION__);
    }

    public function test_error()
    {
        throw new \RuntimeException(__FUNCTION__);
    }

    public function test_skipped()
    {
        $this->markTestSkipped(__FUNCTION__);
    }

    public function test_incomplete()
    {
        $this->markTestIncomplete(__FUNCTION__);
    }

    public function test_risky()
    {
        throw new \PHPUnit_Framework_RiskyTestError;
    }
}
