Chapter 2: Types of Testing

One of the fields on a form contains a text box that accepts numeric values in the range of 18 to 25. Identify the value from invalid Equivalence class.

• 26

• 30

• 19

• 20

A text box accepts numeric values in the range of 18 to 25 (18 and 25 are also part of the class). So this class becomes our valid class. Choose the value(s) from invalid equivalence classes.

• <18

• >25

• 18<=x<=25

In an Examination, a candidate has to score a minimum of 24 marks in order to clear the exam. The maximum that he can score is 40 marks.  Identify Valid Equivalence values if the student clears the exam.

• 22,23,26

• 21,39,40

• 29,30,31

• 0,15,22

One of the fields on a form contains a text box that accepts alphanumeric values. Identify the value from Valid Equivalence class.

• BOOK

• Book

• Boo01k

• 1234%

The Switch is switched off once the temperature falls below 18 and then it is turned on when the temperature is more than 21. Identify the valid equivalence classes when the switch need to be on.

• >21

• >=21

• <18

• <=18

A program validates numeric fields as follows: values less than 10 are rejected, values between 10 and 21 are accepted, values greater than or equal to 22 are rejected. Which of the following input values cover all of the equivalence partitions?

• 10,11,21

• 3,20,21

• 3,10,22

• 10,21,22

Given the following specifications, which of the following values for age are in the SAME equivalence partition?

If you are less than 18, you are too young to be insured.

Between 18 and 30 inclusive, you will receive a 20% discount.

Anyone over 30 is not eligible for a discount.

• 17, 18, 19

• 29, 30, 31

• 18, 29, 30

• 17, 29, 31

Software testing can be broadly classified into two types:

• Manual Test

• Automation Test

• Black box Testing

• White Box Testing

Black box Test Design Techniques are

• Equivalence partitioning

• Control Flow Graph

• Decision Table

• Boundary Value Analysis

A form needs input of numeric 1-255 inclusive. Identify the value of Boundary Value Analysis

• 0,1,255,256

• 0,2,255,257
