phpunit command doesn't work for laravel 4 on windows 7

Question

I\'ve recently installed laravel and have written some tests in /tests directory but when I use phpunit at cmd in the same folder that phpunit.xml

Answer 1

Borrowing from @Chris' excellent answer:
Even better, you can make vendor/phpunit/phpunit/phpunit an environment variable, say "phpunit" and whenever you want to run the test in any laravel project you just call php %phpunit%.
