How to configure PHPUnit in MAMP with PHAR

I wanna test my php codes and I have decided to user PHPUnit for my test.

I have followed steps with official documentation

 $ wget http://ift.tt/18KHIKL
 $ chmod +x phpunit.phar
 $ sudo mv phpunit.phar /usr/local/bin/phpunit
 $ phpunit --version
 PHPUnit x.y.z by Sebastian Bergmann and contributors.

But I am using MAMP with my MacOS X.

So I am not sure how to implement PHAR files in MAMP.

Normally, the documentation tells to use this comment in terminal:

sudo mv phpunit.phar /usr/local/bin/phpunit

And my PHP location is:

/Applications/MAMP/bin/php/php5.2.17/bin/

I've tried to run this comment:

sudo mv phpunit.phar /Applications/MAMP/bin/php/php5.2.17/bin/

I don't know what should I do at this step. Please take a look because it does not work.
