TEACHER: Okay, let's write the test case for a login page.


1) Login using valid user name and valid password.


2) Login using invalid username and valid password.


3) Login using valid username and invalid password.


4) Login using blank username and blank password.


5) Login using invalid user name and invalid password.


6) Enter only password and try logging in.


7) Enter only username and try logging in.


8) Verify whether there should be any minimum characters for username or password.


9) Verify whether forgot your password link is present in the login page.


10) Try SQL injection.
