CRat: A refactoring support tool for Form Template Method

Refactoring is important for efficient software maintenance. However, manual operations for refactoring are complicated, and human-related errors easily occur. Tool support can help users to apply such a complicated refactoring. This paper proposes a refactoring support tool with Form Template Method pattern. The developed tool automatically identifies method pairs that can be refactored with Form Template Method, and suggests information that is required for Form Template Method application. It also has a function that metrics-based filtering for detected method pairs. The function helps users to select method pairs that should be refactored.
