I am testing a React Native app using Appium in Python. This is the first time seeing that the app responds too slow with Appium but works completely fine while testing manually. Any idea on how to improve speed of tests?
One way to improve test speed is use a modern device. For your issue, because the app runs well without also running appium doesn't mean the device is not the culprit. Appium does run on the device while also running the app, so the device needs to be able to run both the app and other apps at the same time well to be able to run smooth appium tests.
