A Capacitor 243,123 app fails in two places: in the web code, where browser tools apply, and at the bridge or in native code, where Android's tools apply. This section attaches Chrome 1 's DevTools to BookNest's WebView, reads its native log, decodes the errors plugins return, and adds the two kinds of automated tests a Capacitor project needs: end-to-end tests on a device and unit tests that fake the plugins.
