Testing

Question 1

What is Normal Test Data

Answer 1

Puting in Inputs that the program would usually get

1-100

Example: 56,24,87,5

Question 2

What is Extreme Test Data

Answer 2

Putting in Inputs which cant go any higher or lower then the programs max or min input

1-100

Example:1,100

Question 3

What is Exceptional Test Data

Answer 3

Making sure the program can handle situations that it has not been designed to cope with

1-100

Examples:Z, %, 200, !, @

Question 4

What are the Three types of Errors

Answer 4

Syntax Error
Logic Error
Execution Error

Question 5

What is Syntax Error

Answer 5

This occurs when the rules of the program code have been broken.

Example: Missing a Braket or Colon

Question 6

What is an execution error

Answer 6

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

Question 7

What is Logic Error

Answer 7

When the program will execute the code without crashing but will produce unexpected results.

Example : Using > instead of < or using AND instead of OR

Question 8

What are the two Testing Techniques

Answer 8

Dry Runs
Trace Tables

Question 9

What is a Dry run

Answer 9

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

Question 10

What is a Trace Table

Answer 10

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

Question 11

What is a BreakPoint

Answer 11

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

Question 12

What is a WatchPoint

Answer 12

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