PHPUnit ReflectionException Method suite does not exist

Question

I'm using PHPUnit version 3.6.2, and always got

PHP ReflectionException: Method suite does not exist in /pathTo/pear/PHPUnit/Runner/BaseTestRunner.php on line 113

when running single test:

phpunit path/to/my/ClassToTest.php

PHPUnit installed using pear, and I'm using php 5.3.6

are there any php configurations i should fix? or this just something that PHPUnit should fix.

the class

<?php

class ClassToTest extends PHPUnit_Framework_TestCase{

    public function testSomething(){
        $this->assertTrue(true);
    }

}

Answer 1

I stumbled upon the same message after enabling xdebug extension.

Try adding this in your php.ini (or comment the line with the 1 for this value) :

    ; 0 is actually the default value
    xdebug.show_exception_trace = 0

If you're using VS Code and getting this exception while trying to debug your unit tests, make sure the Everything box is not checked in Breakpoints pane. Unchecking that box got me rid of this issue:

To understand why "show_exception_trace=1" causes this problem, see: Why does PHPUnit hide my xdebug backtrace?
