PHPUnit cannot find exception class

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?

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.

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

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

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.

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
}

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);
