Those unreasonable hierarchical logic implementation code, do not write code comments, is not according to specifications submitted, not formatting, naming freely even put queryBatch written queryBitch, will not cause problems subsequent code refactoring. Then we will separately introduce how to develop ...

Then we had both DesignAttributes and a new test class inherit from AbstractPinRenamer, and changed the Module code to interact with an AbstractPinRenamer rather than a DesignAttributes. Now the test code could interact with the smaller test class, while the production code still used a Design...
