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
The phpunit executable is not in your project root folder, that's why it can't find it.
Now I assume that you already have phpunit in your composer.json file, something like this:
"require-dev": {
"phpunit/phpunit": "3.7.*"
}
When installed by composer, the package will be installed to vendor/vendor_name/package_name. So to run it at your project root, type this command:
vendor/phpunit/phpunit/phpunit
