Testing and Test Data

Question 1

Why does a program need tested?

Answer 1

To make sure there aren’t any errors.

Question 2

What are the two types of testing?

Answer 2

Iterative testing
Terminal (final) testing

Question 3

What is iterative testing?

Answer 3

Testing during development, e.g. throughout the writing of the code.

Question 4

What is terminal (final) testing?

Answer 4

Testing done at the end to make sure that no errors occur when all the modules interact with each other. Making sure you have a working program to release.

Question 5

What are the 4 types of test data?

Answer 5

Normal
Boundary
Invalid
Erroneous

Question 6

In terms of test data, what is NORMAL?

Answer 6

What you would expect to be input, somewhere in a range, such as the middle value, e.g. range 1-10, 5 is entered.

Question 7

In terms of test data, what is BOUNDARY?

Answer 7

The limits of what should be expected, e.g. range 1-10, 1 is entered to test the lower boundary and 10 is entered to test the upper boundary.

Question 8

In terms of test data, what is INVALID?

Answer 8

Correct data type that should not be accepted because it is outside of the range, such as the middle value, e.g. range 1-10, 16 is entered.

Question 9

In terms of test data, what is ERRONEOUS?

Answer 9

The wrong data type, such as the middle value, e.g. range 1-10, “five” is entered.

Question 10

What is the purpose of test data?

Answer 10

So the programmer can check that the program is thoroughly tested and works as intended.
