Run function before all tests in PHPUniit - php

Question

I am looking at PHPunit for running Selenium tests and can run tests fine. What's missing though is the ability to run a function before the tests are run (let's say to set up some config).
<?php
require_once 'SeleniumTest.php';
class MyTest extends SeleniumTest
{
public function testTest1()
{
$this->runSelenese(__DIR__ . '/test1.html');
}
public function testTest2()
{
$this->runSelenese(__DIR__ . '/test2.html');
}
}
The config file is just a regular html file, but needs to be run once before anything else is run
Edit
Another read of the setUp() function has led me to believe that my tests should be setup as follows.
What I want to simulate is a user logging in, setting up some config, running the test and then logging out of the application at the end of the test.
This is what I have come up with; please advise on what I have done wrong, as the tests don't run at the moment. All tests timeout: is this how I should be approaching this?
<?php
require_once 'SeleniumTest.php';
class MyTest extends SeleniumTest
{
public function setUp()
{
$login_path = '/login_path/Login.html';
$logout_path = '/logout_path/Logout.html';
$config_path = '/config_path/config.html';
$this->runSelenese($login_path);
$this->runSelenese($config_path);
$this->runSelenese($logout_path);
}
public function testTest1()
{
$this->runSelenese(__DIR__ . '/test1.html');
}
public function testTest2()
{
$this->runSelenese(__DIR__ . '/test2.html');
}
}
