In this tutorial we shall show users the usage of JUnit Example Web JWebUnit is a Java based testing framework for web applications. Along side of development lifecycle, most of us looking for a way to be sure that the unit of work that has been written is working properly and committed. Tutorial. The QuickStart contains sample code and guidance to get you started with jWebUnit. Creating a TestCase jWebUnit uses two approaches for creating.

Behaviour-driven development is a great way to design and build the web layers of your application. It runs in memory, so it’s fast.
Create test cases for Web applications
However, it also has an intuitive, high-level API, making it easy to use even if you have only an approximate idea of the exact HTML details of your application screens. A simple JWebUnit test case is shown here:. JWebUnit works fine like this, but we can still do better by adding a little BDD-flavoring to the mix.
As it turns out, behaviour-driven development or “behaviour-driven design” is a great way to model user interaction with your application.
Web Testing BDD-style With JWebUnit and Easyb
In BDD, you structure your requirements in a “given [some condition or state], when [some event occurs] then [we expect something else to happen]”. Like many BDD frameworks, easyb lets you express your requirements more precisely, your user’s behaviour in almost plain English, before filling in the details with test code.
For example, here is a working Easyb test scenario describing how we might interact with our banking application:.
As far as Easyb is concerned, this is executable test code – however it won’t do very much. When you run Easyb against a scenario like this one, it will be flagged as “pending implementation”.
So now let’s see how we can implement this test using JWebUnit. However, Easyb is built on Groovy. The only trick is that we still need to have a class that extends WebTestCase, as it is an Abstract class. We also need to initialize the internal ‘tester’ member variable with an instance of the WebTester class.
JUnit – Extensions
A simple Groovy class like this will do the trick. We also need to create a new tutrial of this class for each test case.
Although this seems longer than the Java version, it is arguably more readable, and reflects the intention of the code more accurately than the Java equivalent. The test report also makes it quite clear what requirements are being tested, in very readable terms.
Writing the tests using a BDD approach also helps you keep a good perspective on how closely your application actually does what your users have asked for. Reports like the one above can also give users and testers a better understanding of what is being coded.
