Understanding Test-to-Code Traceability Links: The Need for a Better Visualizing Model

Visualization of test-to-code traceability links is a great approach to understand test-to-code relations. It efficiently supports software developers in various software development activities throughout the software development life cycle (SDLC) by browsing, recovering and maintaining, links between various software artifacts. However, only a small portion of research has been done on visualization of test-code relations and its importance in maintenance, comprehension, evolution, and refactoring of a software system. This paper extensively draws attention of the reader/researcher to the usefulness of visualizing test-to-code traceability links and opens up several research questions or research paths for further advanced exploration.
