Introduction to GWT
"Google Web Toolkit: Your Shortcut to Ajax Web Applications" by Daniel Wellman
An overview of GWT, appeared in Better Software magazine in October 2008.
"Reveling in Constraints" by Bruce Johnson, GWT Tech Lead. acmqueue, Vol. 7 No. 6 - July 2009
Explains why the GWT team chose Java and how GWT solves common AJAX development problems.
The Tutorial on the Google Web Toolkit project page is an excellent way to tour the framework
Comparison of GWT to other AJAX Frameworks
Matt Raible's (of AppFuse fame) comparison of GWT, Dojo, YUI, and Ext JS
A balanced discussion at Stack Overflow about GWT pros and cons
Readings on Model-View-Presenter and Testable UIs
"GUI Architectures" by Martin Fowler, which include the Supervising Controller and Passive View variations.
"The Humble Dialog Box", by Michael Feathers is one of the original papers on designing testable GUIs.
"Presenter First", by Atomic Objects is a pattern similar to MVP used for building GUIs test-first.
Testing and GWT
"Google Web Toolkit: Writing Ajax Applications Test-First" by Daniel Wellman
Explains the different ways to test GWT applications, including an example of using Model-View-Presenter. This article was also adapted and included in the GWT documentation as Testing Methodologies Using Google Web Toolkit.
Matt Raible's blog "Testing GWT Applications" lists many online articles for GWT testing.
My blog "Mocking GWT Widgets with GWTMockUtilities" explains how to write plain ol' JUnit TestCases when you need to mock GWT widgets, instead of requiring a GWTTestCase.
Google Testing on the Toilet: Testing GWT without GWTTestCase from August 8, 2009 provides more information on MVP in GWT.
