Eroneous
Beyond Range (not sensible) e.g. 6, 1.5
Data which has been specifically identified for use in tests
Data Sanitisation
Reduces inputted waste
Makes sure the inputted data can be processed (changing numbers into integers)
Authentication
The plan when entering a password and username
Security Procedures
How many entries of password until locking
Maintainablity
Maintaining System Coding
Updates for Coding
Comments
Comments done by users left in the coding to help other people to maintain the system
Indents
Organisation of Coding
Makes it easier for people to look and read the code
e.g. Spaces in between code
Testing
Tests in Coding
Two Types
Iterative
Test as you go along
Constantly checking coding
Final/Terminal
Tests/checks done at the end
Tests you've identified can be done by:
Client - Person who provides the reqiuirement
User - Maintains the System
