Atoms of Confusion (AoC) are indivisible code patterns that may cause confusion for developers when trying to understand them, and that have less confusing equivalent patterns. Previous works suggest it is a good practice to avoid them. While there are studies on AoC relating them to bugs, there is not much about their relationship with the practices of Continuous Integration and Continuous Delivery (CI/CD). Since CI/CD is generally praised as a group of good practices, related to better code being released reliably and faster to clients, there’s a possibility that the presence of CI/CD would also impact the presence of AoC, possibly making them less prevalent since they can be problematic to development processes. To clarify this relationship, we analyzed 10 open-source long-lived Java libraries and 10 open-source Java projects for Android, to see if there was any difference in the AoC rate before and after the implementation of CI/CD. Our results show the AoC rate changed for all projects, but we could not find a statistically relevant relationship between these changes and CI/CD.
