The Application Code Reviewer (ACR) is a cloud-based tool developed by CLEVR. It is specifically designed to accelerate the code review process in developing applications using the Mendix platform.
ACR makes it possible to automate the mundane aspects of the code review process in a way that allows developer teams to focus their efforts on more complex challenges.
The goal is to help the developer write better code, improve junior developer coding confidence, and save time for senior developers doing peer-review. To achieve this, ACR checks your Mendix application against over 150+ Mendix best practices and security standards.
You find all the rules that are in ACR documented here.
All this is done to assist the developer. The goal is never to change code to obey a rule artificially. When the violation indicates a bad coding practice, you need to improve your code or accept lesser quality.
