Details

(1) product Overview : Telecom application which have functionality to work with SMS,CALLS and CONTACTS for business enterprises solution .
(2) Test running challenges :
(i)Product point of view we are using Robot framework using RIDE as IDE tool for Automating our test suite using Selenium and Appium Library.
(ii)While running more than 50+ scripts appium server stops the response and throw bad server error ,which leads to failures of rest scripts in the suite
(iii)Changing from default to any other port number also not worked out much (e.g; default from 4723 to 4725)
(iv)Also, we have some scenario where we have to do cross platform testing with (Web+Mobile).
(v)We are not only checking the cases within the application as we are doing touch base on Mobile Native application as well like - dealing with network connections to ON or off the wifi ,Data , etc
(vi) we are getting element not found several times where we can see the element is present in the screen, we have tried with all sync options and looks like it is the response from Appium server which Is causing the problem
