PHPUnit cannot find exception class

Question

I am using namespacing in 5.3 and trying to test for an expected exception in PHPUnit with the Symfony2 framework.

I am expecting an exception to be thrown and when I use the

$this->setExpectedException('ImageResizerException');

I get the following error:

PHPUnit 3.7.13 by Sebastian Bergmann.

Configuration read from /var/www/branches/3.6.0/api/app/phpunit.xml.dist

.E.................

Time: 1 second, Memory: 18.25Mb

There was 1 error:

1) AssetManagerBundle\Tests\Services\ImageResizerTest::testOriginalFile ReflectionException: Class ImageResizerException does not exist

FAILURES! Tests: 19, Assertions: 54, Errors: 1.

I have the following structure:

1. AssetManagerBundle\Services\ImageResizer.php
2. AssetManagerBundle\Services\Exceptions\ImageResizerException.php
3. AssetManagerBundle\Tests\Services\ImageResizerTest.php

My test class:

<?php
    namespace AssetManagerBundle\Tests\Services;

    use AssetManagerBundle\Services\ImageResizer;
    use AssetManagerBundle\Services\Exceptions\ImageResizerException;

class ImageResizerTest extends \PHPUnit_Framework_TestCase
{

    public function testOriginalFile()
    {
        $ir = new ImageResizer();
        // test default value
        $this->assertEquals('', $ir->getOriginalFile());

        // test invalid filename
        $this->setExpectedException('ImageResizerException');
        $ir->setOriginalFile('/tmp/test.file');
        $this->assertEquals('/tmp/test.file', $ir->getOriginalFile());


        // test valid filename
        $temp_name  = tempnam(sys_get_temp_dir(), 'test_'.time());
        $handle     = fopen($temp_name, 'w+');
        fwrite($handle, ' ');
        fclose($handle);

        $ir->setOriginalFile($temp_name);
        $this->assertEquals($temp_name, $ir->getOriginalFile());
    }
    // more code....
}

Do I have to do something special for PHPUnit to see my exception class?

PHP Version:

PHP 5.3.10-1ubuntu3.5 with Suhosin-Patch (cli) (built: Jan 18 2013 23:45:59) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies with Xdebug v2.1.0, Copyright (c) 2002-2010, by Derick Rethans

Answer 1

You need to fully qualify the exception class along with its namespace. For ex:

$this->setExpectedException('\AssetManagerBundle\Services\Exceptions\ImageResizerException');

or

use AssetManagerBundle\Services\Exceptions\ImageResizerException;
$exceptionClass = get_class(new ImageResizerException(''));
$this->setExpectedException($exceptionClass);

Answer 2

You need to use the FQCN of the ImageResizerException exception:

AssetManagerBundle\Services\Exceptions\ImageResizerException

The use clause on top of the file is for that file only - not for PHPUnit which has it's code in some other files.

Correction: It's not (only) that the use clause does not work for PHPUnit but because that ReflectionClass expects a FQCN. That is similar when use a variable (dynamic) class-name in PHP like new $var:

<?php

namespace Sugar {
    class Exception extends \Exception {}
}
namespace {
    use Sugar\Exception;

    $class = 'Sugar\Exception';
    $e = new $class;
    var_dump($e);
}

Output:

object(Sugar\Exception)#1 (7) {
  ["message":protected]=>
  string(0) ""
  ["string":"Exception":private]=>
  string(0) ""
  ["code":protected]=>
  int(0)
  ["file":protected]=>
  string(45) "/tmp/execpad-7141d0116de7/source-7141d0116de7"
  ["line":protected]=>
  int(10)
  ["trace":"Exception":private]=>
  array(0) {
  }
  ["previous":"Exception":private]=>
  NULL
}

Answer 3

Instead of writing the class name, use the full namespace of the class instead. Then you will not get the 'class doesn't exist' exception.

Answer 4

    $this->setExpectedException(ImageResizerException::class);

is the way to do it using the imported namespace from the use statement

Answer 5

I've had a similar issue, but with phpunit, while declaring the @expectedException, it also needed the FQCN.

 /**
 * @expectedException \PHPNS\Core\MyCustomException
 */
public function testIfListIsEmpty()
{
    $fab = new PHPList();                         
}

Hope that helps someone.
