Automatically testing an Appian UI using Selenium?

[priyasony]

The goal is to automatically test an user-interface created with Appian from within Azure Devops' Testing Center with the help of Selenium.
The interface to be tested is an [url]Appian Training[https://hkrtrainings.com/appian-training] form with multiple pull-down menus, and the challenge is that the page is built dynamically with no obvious, stable CSS-properties of each element. Even the names of the respective elements seem to change. The dirty workaround we are currently pursuing is to find the correct pull-down-menus with regular expression, which is rather tendersome and requires constant development effort.
