The document outlines test cases for an online shopping system. It includes test cases for the registration, login, and shopping cart modules. For the registration module, test cases verify successful user registration with a unique email ID, validation of the registration with an OTP, and successful login after registration. Login test cases validate successful login with valid credentials, failed login with invalid credentials, and password reset functionality via OTP. Shopping cart test cases cover adding an item to the cart successfully, displaying the total cart amount, removing an item from the cart, and proceeding to checkout when items are in the cart.
