A Robust Framework for Automated Shiny App Testing
summary
A reproducible pipeline that automates pre- and post-deployment checks for production Shiny apps using shinytest2 and Selenium, plus rvest and testthat for assertions and scraping. The system runs scripted UI interactions, captures screenshots and JSON snapshots, and stores artifacts in a repo with GitHub examples and an ice cream demo app. Deployment time drops from five days to five hours in one case, and test logic becomes consistently repeatable across runs.
