How to Write Test Cases for Login

As a software tester, you should always think like a person who is using it, and you need to imagine various scenarios, which will happen in the real time environment. If you do this creative visualization you are rest assured that the application is more or less an error free. Just always see the application in a Negative way, as a software tester your attitude must be always negative with the application, if you have this attitude you can easily find out the mistakes.

The basic objective of writing test cases is to validate the testing coverage of the application. Well written test cases can make the testing cycle smooth and efficient. A good test case is easy to determine if a feature of an application is working correctly.

    Actually, a well-designed log-in page should never divulge whether the user name or the password is incorrect. The correct response for both TC-002 and TC-003 should be "Invalid user name or password", or similar. Apart from that, thanks for sharing.

    Hi mam,

    Great Posting but my interview exp i went attend one interview i tried to write like that but interviewer told we are not expecting this type of template we want only concept for scenario. I dont know why people behave like this, they have to inform before starting the written test but never told anything. At last simply told ur name is not shortlisted, it is the shame for those companies.

    Never say 'Username is wrong' or 'Password is wrong' . We won't give correct messages for login screens. You can also add Keyboard functionalities test cases like tab order , reverse tab order and enter key functionalities.
    Also try to to incorporate some aesthetic test cases also like look and feel, enough space between username and password labels , visibility of buttons and the fonts

    This is good article. Another scenario I can think of:

    1) Login with valid uid and password

    2)then copy the loggedin url from the browser say from IE
    3)Paste it in another browser say firefox.
    4)It should not show you the logged in user details as the login cookies does not exist for firefox.

    Thanks

    1) Incase of Invalid Username or Password, You should expect a common message "Authentication failed. Otherwise it is a security defect.

    2) Now a days Login comesup with ADS Sever integrations. Need cases around

    3) * mark should appear always for mandatory field. Its not after using missing it.

    You can write around 60 Testcases for the given scenario

    Hi Suriya,

    Thanks for providing the TC details for Login, But i have one suggestion when we are validating the "Password By entering invalid password then an error message should appear as " Please Enter Correct Password "" in this case Error message should never say that Please enter correct password due to security issue if user enters incorrect Password but the username is correct or vice-verse the error message should say that Either username or password is incorrect.
