Code Review
This pull request refactors the integration tests for the web-server device, introducing new tests for hot reload and hot restart functionality along with a new WebServerDeviceTestRunner helper class. Feedback on the implementation focuses on robustness and resource management within the test runner. Key recommendations include tracking the runner's lifecycle with a disposal flag, using a stopwatch-based timeout in the browser log search to prevent infinite background loops, and wrapping webdriver cleanup in a try-finally block to guarantee that chromedriver processes are always terminated.

Just some nits about error reporting, LGTM otherwise.

Code Review
This pull request reorganizes and adds integration tests for hot reload and hot restart on the web-server device, introducing a shared WebServerDeviceTestRunner utility and removing older WebSocket-based tests. Feedback on the changes includes addressing an uncaught TimeoutException in findNextInBrowserLog that bypasses custom error handling, avoiding throwing exceptions on non-fatal ChromeDriver stderr output to prevent test flakiness, and simplifying the commentHotReloadPrint helper by writing the original template directly instead of performing string replacement.

LGTM! I think it makes sense to just always surface the errors. If it's too noisy, we'll find out in CI.
