'Class not found' when using namespaces in PHPUnit

Question

I'm new to PHPUnit and am having some trouble setting it up to access my PHP files. The directory structure I'm using for my app is this:

./phpunit.xml  ./lib/Application/   -> Dir1/File1.php (namespace = Application\Dir1)   -> Dir1/File2.php   -> Dir2/File1.php (namespace = Application\Dir2)  ./tests/Application/Tests   -> Test1.php (namespace = Application\Tests)   -> Test2.php  

In my PhpUnit.xml, I have:

<?xml version="1.0" encoding="UTF-8"?> <phpunit verbose="false">   <testsuites>       <testsuite name="Application">           <directory>./tests/Application/Tests</directory>       </testsuite>   </testsuites>   <logging>        <log type="coverage-text" target="php://stdout" showUncoveredFiles="false"/>        <log type="json" target="/tmp/phpunit-logfile.json"/>   </logging>   <filter>         <whitelist>             <directory suffix=".php">./lib</directory>         </whitelist>   </filter> </phpunit> 

And in one of my test files, I open with:

namespace Application\Tests;  use Application\Dir1\File1;  class MyTest extends File1 {} 

But it keeps on saying:

Class 'Application\Dir1\File1' not found

Where am I going wrong?

If you installed PHPUnit using Composer then you can use Composers autoloader. The easiest way to do so would be to add:

"autoload":{     "psr-0":{         "your-app-directory":""     } } 

to composer.json
