 ## Directory Testing
 Instead of file by file testing, use **assertValidPHPDirectory** to test an entire directory. Any files added to the directory will be automatically tested.
 ```php
-	$this->assertValidPHPDirectory(__DIR__ . '/../App', 'App directory error');

 ```
 The error message will include the offending file name and line number.
