Agenda

6. Problem #1
FLAKY App

7. Problem #2
Driver Limits

8. Problem #2
Weather refreshing every 30
min.
How to automate this case?

9. Problem #3
• Firstly, Login takes 30 seconds
• And Then dismissing “What’s new” takes another 30 sec
• I don’t want to repeat this in each test
Our tests are so slow.

10. Appium
Backdoors

11. public class LoginActivity extends Activity {
public void foo() {
// code to set some app state
// Or seed DB before test
// Or Disable ‘Rate Us’ popup
}
}

12. public class LoginActivity extends Activity {
public void foo() {
// code to set some app state
// Or seed DB before test
// Or Disable ‘Rate Us’ popup
}
}

13. Demo

14. • Change Backend URLs
• Change App Locale
• Getting session_id from app
• Disable “What’s new” tutorials after login
Where do we use Backdoors?

15. • Disable client side A/B tests
• Faking SIM card for payments
• Get Analytics data from app to validate it
Where do we use Backdoors?

server/tree/single_apk
•There is a special backdoor handler in above fork
•gradle clean assembleServerDebugAndroidTest

28. $ gem install 'appium_instrumenter'
$ appium_instrumenter instrument my_app.apk

29. $ gem install 'appium_instrumenter'
$ appium_instrumenter instrument my_app.apk
$ adb install appium-uiautomator2-server-debug-

$ adb install appium-uiautomator2-server-
v0.3.0.apk

30. On Client side..
curl -X POST -H "Content-Type: application/json"
http://localhost:<forwarded_port>/wd/hub/sess
ion/:sessionId/backdoor
-d
'{"methods":[{"name":"<method>",
"args":["<method_arg>"]}]}'

31. On Client side..
def backdoor(*args)
url =
"http://localhost:#{FORWARDED_PORT}"+
“/wd/hub/session/:sessionId/backdoor"
body = {'methods' => args}.to_json
# code to post data
end

32. On Client side..
def backdoor(*args)
url =
"http://localhost:#{FORWARDED_PORT}"+
“/wd/hub/session/:sessionId/backdoor"
body = {'methods' => args}.to_json
# code to post data
end
backdoor({name:”methodName",args:["Arg"]})

34. Quiz
1. Add a backdoor method to change refersh interval:
changeRefreshInterval(time)
2. Add a backdoor method to refresh weather
refreshWeather()
Weather refresh every 30 min. How will you
test this case?
