Is there a way I can have PHPUnit just continue after an error? For example, I have a large test suite (400+ steps) and I would prefer that if say, an element is not found, it doesn't stop the rest of my script from continuing.

We do the same thing in our Selenium tests. You need to catch the exceptions thrown for assertion failures, and the only way to do that is to create a custom test case base class that overrides the assertion methods. You can store the failure messages and fail the test at the end using a test listener.
I don't have the code in front of me, but it was pretty straight-forward. For example,
abstract class DelayedFailureSeleniumTestCase extends PHPUnit_Extension_SeleniumTestCase
{
public function assertElementText($element, $text) {
try {
parent::assertElementText($element, $text);
}
catch (PHPUnit_Framework_AssertionFailedException $e) {
FailureTrackerListener::addAssertionFailure($e->getMessage());
}
}
... other assertion functions ...
}
class FailureTrackerListener implements PHPUnit_Framework_TestListener
{
private static $messages;
public function startTest() {
self::$messages = array();
}
public static function addAssertionFailure($message) {
self::$messages[] = $message;
}
public function endTest() {
if (self::$messages) {
throw new PHPUnit_Framework_AssertionFailedException(
implode("\n", self::$messages));
}
}
}

There is a better way to do this. Instead of overloading every assert*() method you can overload just one method: runTest(). It is for each assertion, and exceptions can be caught:
abstract class AMyTestCase extends PHPUnit_Framework_TestCase
{
public function runTest()
{
try {
parent::runTest();
}
catch ( MyCustomException $Exc ) {
// will continue tests
}
catch ( Exception $Exc ) {
if ( false === strpos($Exc->getMessage(), 'element not found') ) {
// rethrow:
throw $Exc;
}
// will also continue
}
}
}
