To enable testing Java classes which use SmartGWT's classes, and their native methods, we want to replace these methods with pure Java implementations, so they can be used in JUnit tests.
Of course, we won't provide Java implementations of the widgets (these are better tested in integration tests, using Selenium or similar tools), only the pure data parts which are easily mockable.
This work is based on SmartGWT, LGPL edition, and thus available under terms of the GNU Lesser Public General License, version 3.
It also partly relies on Google Web Toolkit, which is available under the Apache License v. 2.0.
