Design and Testing

1. Input Validation

   • Ensures that the data that is being inputted is reasonable and sensible
   • This may be a certain criteria for certain codes and programs.
   • E.g. If a user wanted to input their email address to let them register an account. The validation would check that the email is written in the correct form. (@, .co.uk, .com)

2. Input Sanitisation

   • Where the data is removed of any unwanted characters that the user may enter.
   • E.g. if a user is trying to enter a password. the code would strip out any spaces to help prevent the potential threat of an SQL injection attack

3. Formatting

4. Commenting

5. Indentation
