PHPUnit (Phar) Fatal Error Only When Test Fails

Question

I have chosen to use a Phar of PHPUnit (phpunit-4.8.26.phar) to unit test my custom built PHP Framework and Application. The reason I am using the old stable release is because I need compatibility with PHP 5.4.29.

The reason I have chosen not to use Composer to get PHPUnit is because it's tends to pollute my vendors folder with dependencies. I like to keep it as lean as possible.

I am using Windows 7 Pro SP1, WampDeveloper v5.4.0.1, ProPhpStorm 2016.1.2, Phing and a whole bunch of other cool stuff to do my thing.

The Problem

• I CAN run a passing unit test successfully from within PhpStorm.
• I CAN run a group of passing unit tests successfully from within PhpStorm.
• I CAN NOT run a FAILING unit test successfully from within PhpStorm.
• I CAN run a passing unit test successfully from the command line.
• I CAN run a group of passing unit test successfully from the command.
• I CAN NOT run a FAILING unit test successfully from the command line.

Instead of PHPUnit display a typical test failure message it exits with the below errors:

Warning: require(Composer\Autoload\ClassLoader.php): failed to open stream: No such file or directory in D:\WampDeveloper\Websites\qclean.development\bootstrap\Autoloader.php on line 23

Fatal error: require(): Failed opening required 'Composer\Autoload\ClassLoader.php' (include_path='.;D:\WampDeveloper\Tools\PEAR\pear;D:\WampDeveloper\Tools\PEAR;D:\WampDeveloper\Components\Php\PEAR;D:\WampDeveloper\Tools\PHPMailer;') in D:\WampDeveloper\Websites\qclean.development\bootstrap\Autoloader.php on line 23

Supporting Info

My directory structure:

My unit test script ConfigurationTest.php

<?php
/**

 */

namespace nova\tests\configuration;

use PHPUnit_Framework_TestCase as TestCase;

/**

 */
class ConfigurationTest extends TestCase
{
    protected function setUp()
    {
        parent::setUp();
    }
    
    public function test()
    {
        $result = false;
        
        $this->assertTrue($result);

And lastly my Autoloader Autoloader.php

<?php

// Ref: https://github.com/philsturgeon/fig-standards

/**
 * Define the application autoloader function.
 */
function autoload($className)
{
    $className = ltrim($className, '\\');
    $fileName = '';
    $namespace = '';
    
    if ($lastNsPos = strrpos($className, '\\'))
    {
        $namespace = substr($className, 0, $lastNsPos);
        $className = substr($className, $lastNsPos + 1);
        $fileName  = str_replace('\\', DIRECTORY_SEPARATOR, $namespace) . DIRECTORY_SEPARATOR;
    }
    
    $fileName .= str_replace('_', DIRECTORY_SEPARATOR, $namespace) . '.php';
    
    require $fileName;
}

/**
 * Register the autoloader functions.
 */
spl_autoload_register('autoload');

The error and warning indicate the inability to load the Composer\Autoload\ClassLoader.php file. What I don't understand is why it is asking for this file when I am using a Phar? Reading snippets off the internet indicate the Phar should have an internal autoloader though I am unable to see one.

I do not want to have to install Composer just to get it's autoloader. That would defeat the purpose of trying to solely use the Phar.

I added the PHPUnit Phar path to my Windows %path% but this did not make any difference. I understand that this should be done if PHPUnit was installed using PEAR.

Any help on this 'hair pulling out matter' would be greatly appreciated...

Answer 1

All what you need to do it to go to Settings > Language & Frameworks > PHP > PHPUnit and Choose PHPUnit library - and set path to phpunit.phar, that's all.

Answer 2

If you look at the stack trace, you'll see that the error is triggered on class_exists. This function calls __autoload by default. This means that the autoloader you registered will be called. In this case it will be called for a class that exists outside of your project.

So you should add an extra file_exists check to your autoloader before requiring the file. You're requiring a file that doesn't exist.

if (file_exists($fileName)) {
    require $fileName;
}

Or just suppress the error (require doesn't throw an exception, so use @):

@require $fileName;
