Hello all, I'd really like to use the validation part of incubator, but I'd like to do the following updates and design changes:
Update to use Java 1.5 features that are now available -------- This is pretty straight forward. I would use typed lists in AbstractValidationController, make Subject a generic interface (for the value returned), and other minor changes. Use interfaces instead of abstract classes -------- A lot of the main validation classes are abstract classes. Some examples are ErrorHandler, AbstractValidationController and Validator. This creates a lot of problems for unit testing these classes because you can't really mock them out, you have to instantiate them, etc. Therefore, I think it's better to make these classes interfaces and make an abstract concrete implementation that includes the current code. Write test cases -------- The validation library is currently missing unit tests, I'd like to add extensive tests. I wanted to use EasyMock (http:// www.easymock.org/) for testing some of the stuff that doesn't involve GWT.create() calls. EasyMock is under the MIT license, is it acceptable to use and include? Remove static methods -------- There are a number of static methods scattered around in classes like the DefaultTextBoxSubject, RegExValidator and ValidatorController. Static methods really make testing hard, and global states are in general bad. Is there a specific reason for these static methods? Annotation based validation -------- What do you think about annotation based validation? It could look something like this: @NotEmptyValidator TextBox firstName = new TextBox(); @NumberRangeValidator(low = 18, high = 100) TextBox age = new TextBox(); Let me know what you think. Thank you.
