Issuing the following zend_tool command:

 

Creates the following:

Creating a controller at /var/www/website/application/modules/demo2/controllers/Hello-worldController.php [..] Creating a view script for the index action method at /var/www/website/application/modules/demo2/views/scripts/hello-world/index.phtml Creating a controller test file at /var/www/website/tests/application/controllers/Hello-worldControllerTest.php [..]

 

Correct would be:

Creating a controller at /var/www/website/application/modules/demo2/controllers/HelloWorldController.php [..] Creating a view script for the index action method at /var/www/website/application/modules/demo2/views/scripts/hello-world/index.phtml Creating a controller test file at /var/www/website/tests/application/controllers/HelloWorldControllerTest.php [..]````
