First of all am sory if am asking you the very basic question, but am forced for it being only tester in our company.

Actuly my problem, consider i have to check the login page and automate it, my testcases are as below,

Valid login,
Invalid login,

And while automating should i use two actions for single login screen named valid login and Invalid login,

Or i should validate valid or Invalid in single action, throuh vbscript,as am from programming background.

And i need to run only perticular testcase in qtp if its failed by considering the testcase id, how can i do it?

Am asking these questiong because am the only tester and there are no frame works mentatined for testing in our company, so i want to step into right way now.

Thanks in Advance.
