Making Program Refactoring Safer

User Manual

After installed in the Eclipse, the plugin features are enabled through a SafeRefactor option in the menu bar. The drop-down menu lists the currently supported refactorings.

How to refactor using SafeRefactor?

The steps to refactor using SafeRefactor are similar to the traditional way of Eclipse refactoring:

1. Select the part of the code which will be refactored in the Java Editor. For example, if one wants to Push Down a method, she selects the name of the method in its signature;
2. Choose the desired refactoring in the SafeRefactor drop-down menu;
   
   
   
   
3. In the wizard, click on the SafeRefactor button and wait the process to be completed;
   
   
   
   
4. Check the result showed by the plug-in.
   1. If the refactoring is not safe to be applied, a message is shown, as well as which tests have broken. To view the source of the broken tests, just double-click on the test name in Failed Tests list.
      
      
      
      
   2. Otherwise, close the window and apply the refactoring.
