I am writing a test case for an android app where the app requires case-sensitive credentials. I writing test cases using appium and TestNG.

Steps I am following are -

  1. Launching app
  2. Entering username and password e.g. username : user_test and password : User@123
  3. Tapping on Login button.


  1. App launched successfully.
  2. Entered wrong credentials username: user_test and password: USer@123

The problem here is that it's entering the wrong password. Two characters of a password in upper-case: USer@123.

The function I use to enter text in the password field is -

    So basically you are able to enter case-sensitive credentials but there is some issue with sending the proper keys?

  • Can you please check you have to test password with 2 letters in capital case- in your question "USer@123" and in your script there is only one letter in capital case "User@123"

  • I am entering "User@123", but its typing "USer@123". Yes, some issue with sending the proper keys? @Alexey

  • Try to invoke sendKeys for each particular symbol of your password.

Try breaking it down into three steps:

WebElement password = inspectElement(XpathConstants.PASS_TXT_XPATH);
  • Tried but still same problem exists. Any other way ?

    I've never seen the behavior you're describing before. I would do a global search of my source code for "USer" (obviously case-sensitive search) to see if there is somehow some other code that is getting executed instead of the code you think is getting executed. If all else fails, I would change the password to some other mixed case word and see if the problem persists. May 21, 2018 at 14:21
  • Right, I tried the exact Scenario with my current Android version 4.4.2 and it works well.. I shocked with this crazy behavior.. Need to search more on this..

If nothing else works, you can do the truly horrible workaround of adding a delay to each letter entered (this is assuming that the time to switch from upper-case to lower-case is what is causing your problem).

Your code would do something like this (no guarantees that the code is actually correct - it's a long time since I've worked with Java - but the principle is sound)

string password = "User@123";
char[] pwdArray = password.toCharArray();
for (int i = 0; i < pwdArray.length(); i++) 
   thread.sleep(5); // Adjust the sleep time until entry doesn't take too long but gives the correct result

Make no mistakes, this is a horrible way to fix this problem, but it may be the only way you can do it - especially if you are testing with different credentials.
