Wrong class autoloading and conflicts #2014

soullivaneuh · 2015-12-22T10:19:20Z

This issue is the continuing of #1757 as this is still here with PHPUnit 5.

Actually, php class are loaded first on PHPUnit library (composer or .phar) before project classes.

@Seldaek I take permission to ping you as I'm not really sure it's a PHPUnit or composer issue.

This can break tests if the used class is not the same between PHPUnit and project.

I'll elaborate with 3 concrete cases. First of all, here is my phpunit.xml project file:

<?xml version="1.0" encoding="UTF-8"?>

<phpunit
        backupGlobals               = "false"
        backupStaticAttributes      = "false"
        colors                      = "true"
        convertErrorsToExceptions   = "true"
        convertNoticesToExceptions  = "true"
        convertWarningsToExceptions = "true"
        processIsolation            = "false"
        stopOnFailure               = "false"
        syntaxCheck                 = "false"
        bootstrap                   = "app/autoload.php"
>

    <php>
        <server name="KERNEL_DIR" value="./app" />
    </php>

    <testsuites>
        <testsuite name="Test Suite">
            <directory>./tests</directory>
        </testsuite>
    </testsuites>

    <filter>
        <whitelist>
            <directory>./src</directory>
        </whitelist>
    </filter>

</phpunit>

As you can see in the stack trace, the error occurred on the global vendor classes.

This error is "logic" because guzzle version differs between global and project vendors:

This exception should not be thrown because my project is running under Symfony 2.8 full stack.

But PHPUnit 5 use symfony/yaml component that is bumped to 3.0 version.

PHPUnit as a project dev dependency

If I require phpunit directly on my project and run it:

$ ./bin/phpunit

OK (956 tests, 321 assertions)

It works. But this is a workaround, not the solution. AFAIK, PHPUnit should be able to run standalone, at least with the .phar.

The text was updated successfully, but these errors were encountered:

This isn't really a composer issue, and there is nothing we can do about it. The solution for phpunit might come with https://github.com/webmozart/php-scoper - in the meantime requiring it in your project is the best way, and I'd anyway argue it's the best way as it's the only way to guarantee you get the right phpunit version for every project.

Thanks for answering.

Well, adding PHPUnit with all dependencies on each project is quite painful IMO but yes, there is many way to do.

Anyway, PHPUnit can be installed on system wide (even if via apt-get) and I think this should work on standalone process.

This isn't really a composer issue, and there is nothing we can do about it. The solution for phpunit might come with https://github.com/webmozart/php-scoper

If I understand well this tools, this should be added on PHPUnit project to generate a unique namespace for the .phar of composer global install, right?

sebastianbergmann · 2015-12-23T08:53:26Z

Right.

soullivaneuh · 2015-12-23T08:55:15Z

Sorry but why closing this issue?

If PHP-scoper is the solution, we should wait to implement it before closing.

lastzero · 2016-01-12T11:21:49Z

As a workaround, @sebastianbergmann might want to bundle the release of Symfony\Component\Yaml\Yaml that comes with Symfony 2.8 instead of 3.0. Symfony >= 3.0 has "deprecated" functionality removed, thus breaking backwards compatibility. Not a great idea for a testing framework which is used for refactoring old applications, right? ;)

iget-master · 2016-04-08T19:19:03Z

This issue is affecting me too, I can't really understand why.

Running the phpunit binary on my project folder don't work. Running it from vendor/bin runs fine.

soullivaneuh · 2018-01-30T16:30:45Z

php-scoper has now stable released. Could this be reconsidered?

EDIT: Only vendor should be prefixed, not PHPUnit classes to avoid confusion on IDE completion for example.

sebastianbergmann · 2018-01-30T16:59:44Z

#2015 won't be implemented in time for PHPUnit 7.0. I am hoping for PHPUnit 7.1.
