Somehow the ruby guys get sexy things done and I often think: why
can't I have that? They also have a knack for naming things in a fun,
but good way. Enter Cucumber.
Cucumber is a Behavior Driven Development tool, and brings human
readable, testable specifications to programming. You can find more
about Cucumber on their website [1], and I urge you to take a look at
the Railscasts [2,3,4] to see it in action. I found it really
enlightening to see this in action and wanted it for myself.
If you're too lazy: this is how a testable, human readable Cucumber
specification looks like:
Feature: Helloworld
In order to greet the world
As a user
I want to see the text Hello World in a browser window.
Scenario: Hello World
Given I am viewing the home page
Then I should see "Hello World"
Running this using maven results in:
[INFO] Feature: Helloworld
[INFO] In order to greet the world
[INFO] As a user
[INFO] I want to see the text Hello World in a browser window.
[INFO]
[INFO] Scenario: Hello World # features/helloworld.feature:7
[INFO] Given I am viewing the home page # WicketSteps.iAmViewing(String)
[INFO] Then I should see "Hello World" # WicketSteps.iShouldSee(String)
Fortunately for us Java weenies, Aslak Hellesøy has created a Java
implementation of Cucumber, and even enabled it for use within Maven:
cuke4duke.
Over new years I've been trying to see if I could get it to work with
Wicket, and those efforts are now available for anyone to take a look
at:

There's not much to see (yet), and I'm hoping for some feedback as to
how you would write your own specifications. Is this something you get
excited about?
