• Only existing users with valid username and password can login
• User will be redirected to welcome page in case of successful login
• Usre will be redireted back to login page in case of failure, with error message (currently not working)

2. Registration

• A new user can register to existing system by supplying a valid name, username, password, email and other information
• If the username already exists user will be prompted with same message (not working currently) and redirected back to the same registartion page
• If user gets registered successfully user will be redirected to welcome page

3. Welcome page

• User can only go to welcome page through loging or registration
• If user tries to access welcome page which is not associated with any session, user will be redirected to login page

TODOs:

• Flash messages for erros are not working currently, need to fix that
• Validation for input format and compulsory input fields
• Password is being sent without any security (https), need to find some way to mock the https behavior
