Cannot find PHPUnit in include path phpstorm

Question

Cannot find PHPUnit in include path is the error message I get when I try to run my code in phpstorm.

In the PHP Settings, my PHP level language is 5

Answer 1

Just encountered this problem myself.

I'm unsure why it is unable to find PHPUnit in the include path (despite the fact that it is there, albeit in all lowercase).

I got around this by changing my IntelliJ Preferences for PHPUnit (under PHP --> PHPUnit). I changed the PHPUnit library settings to Use custom loader and then specified the path to the phpunit executable. On my mac, that was /usr/local/Cellar/php54/5.4.26/bin/phpunit.

UPDATE:

I just discovered that pear now installs PHPUnit as a phar named phpunit. It previously installed the PHPUnit source, which was really nice for reference and code completion in PHPStorm. I think that this is the reason things aren't working any longer with PHPStorm, because it's expecting a php executable and not a php archive.

So, I'm moving away from using pear to install PHPUnit, and I'm using composer instead. This bundles PHPUnit directly as a dependency of my project, which makes it more portable than a system dependency. You'll need to add vendor/phpunit/phpunit as a PHP include path in your PHPStorm preferences. This will serve two purposes:

1. PHPStorm can find the phpunit executable now
2. PHPStorm will index all the PHPUnit classes now, so you'll get auto-complete. Yay!

To do this, go to Languages and Frameworks in the PhpStorm settings. If you click on PHP, on the right you have your include paths
