Here is described old version: http://www.ecomdev.org/2011/02/01/phpunit-and-magento-yes-you-can.html
And they wrote that I need call phpunit UnitTests.php
But I have magento v.1.7. I downloaded newest version: https://github.com/IvanChepurnyi/EcomDev_PHPUnit
But there are not any files like UnitTests.php
How I should run unit test then?
