Syntax and Logic Errors

Syntax Errors

Errors within the code causing program failure

Logic Errors

Errors altering program outcome, not causing failure

Suitable Test Data

Data types for testing program functionality

Normal Data

Accepted data without errors

Invalid Data

Correct data type but does not meet requirements

Erroneous Data

Data not of correct data type

Boundary Data

Data at the edge of specified range

Terminal Testing

takes place once the program has been completed. It tests the whole program at the end of its development

Iterative Testing

Testing sections of code throughout development to ensure it runs correctly throughout the code

Sub-program

Block of code with an identifier called when needed.
Using sub-programs helps in organizing and maintaining code efficiently.

Naming Conventions

General rules for creating identifiers in programming languages
Eg:
Separate words in identifiers using an underscore
• Write constants that will be remain constant throughout the program in capital letters
• When creating classes, start each word with a capital letter
• When creating functions use lowercase letters and separate with an underscore

Maintainability

Ease of future program maintenance through structure and layout
Examples:
Comments
Indentation
Sub programs
Naming Conventions

Indentation

Forced in some languages like Python for program functionality

Input Sanitisation

Cleaning up user input for suitable processing

Validation

Checks if user input is in correct format, not correctness
