How to write test cases for Registration & Login

Writing test cases (which is an important task for a tester in application testing) requires experience and a keen eye for detail in order to build scenarios. This means that an application tester needs to focus on creating a set of variables or conditions which will help him/her to determine whether the software meets requirements and functions flawlessly. To reduce that hassle, we have compiled a list of use cases that you need to test a register or login page. We hope they will help you to create more error-free register/login pages.

Before We Start,

You should gather all the customer requirements you can. The list of requirements which can be useful are:

  1. FirstName
  2. LastName
  3. UserName
  4. Email ID
  5. Password
  6. Confirm Password
  7. Address
  8. Phone Number
  9. Gender

Required Fields are - Email, Password, Confirm Password. Validation For Fields -

  • Email: Should be in a proper Email format.
  • Password: It should have alphanumeric, Length should be 8 to 32.
  • PhoneNumber: Phone Number should have only Numbers, Country code is required.
  • After successful Registration Verification email should be sent to the user.
  • After the first successful Login Welcome email should be sent to the user.
  • On Required fields * should show.

Now, let’s begin with our test cases. Although most testers use Bugzilla to maintain test cases, you can also use Excel or spreadsheets.
