mation available on GWTTestCase focuses on these RPC cases, and I recommend reading it for the full story. For a brief introduction, refer to the GWT documentation page titled “JUnit Integration” in the section “Asynchronous Testing” or, for a deeper example, review the book GWT in Practice [6]. Reflecting on this Design approach My team used the design approach I’ve described in this article on a project and found it worked well. A disadvantage of this design is that it relies on the views’ correctly registering the callback events with the presenter. Since this logic was almost too simple to break, we accepted these limitations on our project. For end-to-end integration tests, we used Selenium to control an instance of Firefox and Internet Explorer. These tests filled in the cracks to ensure we had widgets properly wired into their corresponding presenters. Testing GWT applications, like testing Swing or other desktop client applications, can be fairly succinctly summarized as follows: Don’t put logic in your view components. If you find complicated logic in your view, see if it can be moved into the model objects or the presenters. When you need to test view component behavior, JavaScript, or remote server communication, use a GWTTestCase. If you have too many slow GWTTestCases, see if there’s some design change that doesn’t require testing inside a real browser. Let the tests help guide your design, and you’ll be on your way toward making Ajax development fun and relatively painless. {end} refereNceS: [1] “Compatibility with the Java language and libraries” in the Google Web Toolkit online documentation.
