PHPUnit (Phar) Fatal Error Only When Test Fails - php

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
And a screen shot to expand on the above:
Supporting Info
My directory structure:
My unit test script ConfigurationTest.php
<?php
/**
* Created by PhpStorm
* User:
* Date: 04/06/16
* Time: 12:04 PM
*/
namespace nova\tests\configuration;
use PHPUnit_Framework_TestCase as TestCase;
/**
* Class ConfigurationTest
*
* #package nova\tests\configuration
*/
class ConfigurationTest extends TestCase
{
protected function setUp()
{
parent::setUp();
}
public function test()
{
$result = false;
$this->assertTrue($result);
}
protected function tearDown()
{
parent::tearDown();
}
}
My PHPUnit XML configuration file TestAll.xml
<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
backupStaticAttributes="false"

convertErrorsToExceptions="true"

<exclude>./input</exclude>
<exclude>./request</exclude>
<exclude>./security</exclude>
<exclude>./validation</exclude>
</testsuite>
</testsuites>
</phpunit>
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

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;

Answer 2

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.
