Automated Testing for Web-based Systems on Embedded Devices
summary
Embedded web apps on boards like Raspberry Pi or i.MX6/i.MX8 use real WebKit builds and need tests that exercise system APIs and gestures, not just DOM clicks. The proposal uses WebDriver over HTTP for remote control and the newer WebDriver BiDi via WebSockets to enable console.log subscriptions, DOM change events, and the ability to intercept network requests and inject mock responses. Tools discussed: Selenium, WebDriverIO, Playwright (requires patched WebKit/Firefox), and ongoing WebKit BiDi support to run tests directly against embedded browsers.
