phpunit running exception when run a very very simple unit test - php

Question

I get phpunit and install it as this link using the simplest way for test purposes. I just download the phpunit.phar file, chmod & rename & move to /usr/local/bin
Then, I run phpunit --version, its ok.
I write a simple php test case.
class SimpleTest extends PHPUnit_Framework_TestCase {
public function testSomething(){
$this -> assertTrue(true);
}
}
In terminal , I go to my php class folder, and execute
phpunit --colors SimpleTest
Now I got the exceptions
PHP ReflectionException: Method suite does not exist
in phar:///usr/local/bin/phpunit/phpunit/Runner/BaseTestRunner.php on line 113

Anything is welcome, thanks .

It looks like this error comes from an xdebug setting.
The solution appears to be adding this line to your php.ini file (or changing your the existing value to 0):
xdebug.show_exception_trace = 0
Take a look at
PHPUnit ReflectionException Method suite does not exist and
Why does PHPUnit hide my xdebug backtrace? for more info.
