Summary Motley: Refactoring keeps my design clean from the start, so no more up-front design! Maven: Up-front design is still necessary to achieve clarity on the overall approach (preventing rework later) and needs to be documented to allow others to review your thinking. ______________________________...

Summary Motley: To get high code coverage, we should be testing both public and private methods Maven: Only test public methods. Testing private methods gets in the way of refactoring ______________________________ [Context: Maven checks in on Motley's unit testing practices and...

Summary Motley: Every time I make a change in refactoring I either cause compile problems or break functionality. Refactoring is slow and not worth the effort. Maven: Use tools to refactor and leverage unit tests to improve your confidence that your refactoring does not break functionality...
