What could be the best way to input various combination of username and password into browser in selenium?

Question

I need to test a login form using selenium. The step checks by inputting various combination of the username and password. For eg. . I have used TestNG to perform the test. Is there any other approach that can be used or this is will be fine. Can POM be used for the purpose?

Answer 1

I suggest you to use Cucumber framework with Selenium so that you can define Scenario Outlines including different username and password variations. Here is an example:

Scenario Outline: Sample Scenario: New user onboarding
Given user navigates to blog page
When user clicks "New"
Then user should proceed "Onboarding" screen
Then user enters "<SampleUserName>" to "Mail" area
And user enters "<SamplePw>" to "Mail" area
And user clicks "Submit"
Examples:
  | SampleInValidMail              |  SamplePw  |
  | @example.com                   |  pw1       |
  | #@%^%#$@#$@#.com               |  pw2       |
  | \Joe Smith <email@example.com> |  pw3       |
  | email.example.com              |  pw4       |
