Yet, we know little about the documentation of ASATs, despite it being critical to learn about the coding practices in the first place. We shed light on this through a two-phase study. First, we analyze the documentation of more than 100 rules of 16 ASATs for multiple programming languages, and distill a taxonomy of the goals of the documentation and its types of contents. Then, we conduct a survey to assess the effectiveness of the documentation in terms of its goals and types of contents. We highlight opportunities for improvement in ASAT documentation.
