It allows practitioners to drive web browsers (such as Chrome, Firefox, Edge, or Opera) in an automated fashion using different language bindings (such as Java, Python, or JavaScript, among others). The term ecosystem, referring to the open-source software domain, includes various components, tools, and other interrelated elements sharing the same technological background. This article presents a descriptive survey aimed to understand how the community uses Selenium and its ecosystem. This survey is structured in seven categories: Selenium foundations, test development, system under test, test infrastructure, other frameworks, community, and personal experience. In light of the current state of Selenium, we analyze future challenges and opportunities around it. Keywords: automated software testing; web; selenium; software ecosystems 1. Introduction Selenium (https://www.selenium.dev/) is an open-source framework mainly used for testing web applications. It enables the impersonation of users interacting with browsers such as Chrome, Firefox, Edge, or Opera in an automated manner.
