Task given to me is to derive a test plan I was provided with test_scenario document so I have no idea what I have to draft one of my colleague told me both are same document but I have my doubts about that Please help
A test scenario is: "Check the Authentication feature".
A test plan could be:
log in with valid credentials
log in with invalid credentials for an existing user
log in with credentials for a non existing user
reset the password
and so on.
