Any Functional test suite would involve a fair amount of Negative Test scenarios in it. Usually the expectation here is that whenever a user is doing something which is not supposed to do, he should be stopped and should be shown appropriate error message informing why he cannot proceed any further.
So, how do we accomplish such scenarios scripting in Selenium? I have tried to make use of Java’s Exception handing feature here.
UseCase:
- New User setup is in process
- In the screen where user phone number and Password has to be entered, we get a error message if we enter invalid details
For the purpose of scripting, i considered two scenarios here”
Scenario 1: User enters invalid detail for phone number
Script Alogrithm:
- Create a custom exception class called invalid phone number
- Data validation on the app happens when user clicks Next button on the screen
- hence, I’ve a separate method which just clicks on the Next button and then starts searching for Error message objects on the screen, one after another
- Finally, i start throwing exceptions
- Throw exception for each error message separately. For example – phone number exception. Throw this if only phone number is wrong
- Throw exception for multiple error messages in one shot. For example – if both phone number and password is invalid, throw one common exception for it.
As you can see, point#4 above has to be designed keeping in mind what types of negative scenarios you are automating. You may have create multiple exceptions depending on how many errors each screen may throw. And also you need to keep in mind the multiple error messages that appears on screen, when user inputs wrong data in more than one field on the screen, you need to create separate exception for each kind of combination. Also, you need modify your Test class accordingly, where you catch these exceptions
