PHPUnit Error: Class not found

问题

I'm using symfony 4.0 and using "symfony/phpunit-bridge": "^4.0" in composer.json. I have installed phpunit-bridge using command

composer require --dev phpunit.

Now when I run vendor\bin\simple-phpunit tests/Handler It shows this error

C:\xampp\htdocs\symfonydemo>vendor\bin\simple-phpunit tests/Handler

        $time['secs'] = floor($seconds % 60);
        return $time;
    }
}

Can anyone please me to resolve this error. Thanks.

回答1:

Happening in 4.1 as well, possibly an issue in the bin/phpunit script:

$classLoader->unregister();

I worked around it by creating a tests/bootstrap.php file (and updating phpunit.xml.dist to use it):

<?php

$classLoader = require dirname(__DIR__).'/vendor/autoload.php';
$classLoader->register(true);

回答2:

In your phpunit.xml, you maybe need to specify the kernel and environment :

<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="http://schema.phpunit.de/6.5/phpunit.xsd"
         backupGlobals="false"
         colors="true"
         bootstrap="vendor/autoload.php"
>
    <php>
        <ini name="error_reporting" value="-1" />
        <env name="KERNEL_CLASS" value="App\Kernel" />
        <env name="APP_ENV" value="test" />
        <env name="APP_DEBUG" value="1" />
        <env name="SHELL_VERBOSITY" value="-1" />
  </php>
</phpunit>

回答3:

I ended up with this problem because I forgot to run composer auto-dump -o after installing phpunit.

回答4:

I have just had this problem. Not sure why, but I didn't have a phpunit.xml.dist in the root of my project. None of the examples shows this, but if you add bootstrap= and then include the autoloaded. It should start to find your classes.

<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:noNamespaceSchemaLocation="http://schema.phpunit.de/6.0/phpunit.xsd"
     bootstrap="vendor/autoload.php"
