1) Remember all those things my first year Computer Science professors taught me. Which is to say good programing practice. I have way to much code that has very poor encapsulation, if any at all. I’m thinking to start refactoring things so that only the first level code accesses the main document’s element via DOM. Everything inside of that uses objects or variables passed by a wrapper function.
3) Look for a test framework.
4) Ensure that the SOAP servers that my app requires also have test frameworks.
