Hello,
When I run a sample test on emulator to go to a page and click on an element, it opens Chrome, go to the page and then stops, doesn’t proceed with the other steps. This is the error I get:
org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: Error attempting to start URI. Original error: Error: Error executing adbExec. Original error: ‘Command ‘C:\Users\User1\AppData\Local\Android\Sdk\platform-tools\adb.exe -P 5037 -s emulator-5554 shell am start -W -a android.intent.action.VIEW -d https://Test:[email protected]/ com.android.chrome’ timed out after 50000ms’. Try to increase the 50000ms adb execution timeout represented by ‘adbExecTimeout’ capability
Can anybody help me, I’m new with Appium
