The refactoring of software clones can help to reduce the size of the code-base [1], [2], [3], avoid software defects due to inconsistent clone updates [4], [5], and minimize the negative effect of duplicated code on maintenance effort and cost [6], [7]. Since the beginning, the adoption of refactoring practices was fos-tered by the availability of refactoring catalogues, as the one proposed by Fowler [10]. argue this is because refactoring the smells results in a higher quality design, but also in an increase of object creations and message exchanges.

An available Code Action is announced by a lightbulb near the source code when the cursor is on a squiggle or selected text region. In addition, modern code review increases the awareness of developers on the importance of code refactoring [1, 19]. In this work, we monitor the refactoring activities of test files, belonging to 250 open-source Android apps. All code samples are written in C#, and therefor will follow C# coding conventions (versus any Java coding conventions you might see in the book). In VS Code, Code Actions can provide both refactorings and Quick Fixes for detected issues (highlighted with green squiggles).
