We have a recurring error testing android. When i do “self.driver.background_app(3)” sometimes happends a WebDriverException.
We have to do background to update de xml tree of uiAutomator. If we dont do that, cant wait any element there because never appear.
My question are two:
- can we do another thing to refresh the xml tree?
- what can we do to avoid WebDriverExceptions? good practices or something like that…
Help me pleease!
