Testing

Puting in Inputs that the program would usually get 1-100 Example: 56,24,87,5

Putting in Inputs which cant go any higher or lower then the programs max or min input 1-100 Example:1,100

Making sure the program can handle situations that it has not been designed to cope with 1-100 Examples:Z, %, 200, !, @

Syntax Error Logic Error Execution Error

This occurs when the rules of the program code have been broken. Example: Missing a Braket or Colon

An execution error occurs when a program is asked to do something that it cannot, resulting in a ‘crash’ Example: When asked to divide by 0

When the program will execute the code without crashing but will produce unexpected results. Example : Using > instead of < or using AND instead of OR

Dry Runs Trace Tables

When a programmer manually working through their code to trace the value of variables. Using pen and paper

Trace tables are used to allow programmers to trace the value of variables as each line of code is executed.

Setting a chosen line for the program to stop execution so the values on during the line can be examined

The Program will stop at a line where a variable would be a specific value
