Java developers are used to frameworks such as Tapestry and Struts, which are based on MVC. But Rails takes MVC further: when you develop in Rails, you start with a working application, there’s a place for each piece of code, and all the pieces of your application interact in a standard way. Professional programmers write tests. And again, Rails delivers. All Rails applications have testing support baked right in. As you add functionality to the code, Rails automatically creates test stubs for that functionality.

WEBrick is a pure-Ruby web server that is distributed with Ruby itself and therefore is guaranteed to be available. However, if another web server is installed on your system (and Rails can find it), the rails server command may use it in preference to WEBrick. You can force Rails to use WEBrick by providing an option to the rails command: demo> rails server webrick As the last line of the startup tracing indicates, we just started a web server on port 3000.
Erb template works. Each time we access this page, the user will see the current time substituted into the body of the response. And for our trivial application, that might be good enough. In general, though, we probably want to do something slightly different. We’ll move the determination of the time to be displayed into the controller and leave the view with the simple job of displaying it.
* It is now <%= @time %>
When we refresh our browser window, we will again see the current time, showing that the communication between the controller and the view was successful.
