ISTQB_TestDesignTechniques

Which of the following statements describe why exploratory testing is a useful test design technique?

a. It can help derive test cases based on the internal structure of systems.

b. It is useful when there are limited specification documents available.

c. It is useful when the testing is constrained due to time pressures.

d. It is a cheaper alternative to more formal test design techniques.

• b and c

• a and c

• b and d

• c and d

Which of the following statements correctly describes the benefit of fault attacks?

• They are more effective at finding faults than formal test design techniques

• They are useful when there is limited experience in the test team

• They can evaluate the reliability of a test object by attempting to force specific failures to occur

• They are less structured than other experience-based techniques

From the below given choices, which one is the ‘Confidence testing'

• Sanity testing

• System testing

• Smoke testing

• Regression testing

The following code segment contains a potential "divide by 0" error.

J=50

K=1

while (J>=10) and (N<=10)

loop

M [K] = J/N

K = K + 1

N = N - 1

end loop

Which of the following is the most effective way of detecting this error?

• Boundary testing

• Condition testing

• Compilation of the source code

• Source code inspection

IEEE stands for:

• Information Engineering Endeavouring to Excel

• Institute of Electrical and Electronics Engineers

• Institute of Education for E-commerce Entrepreneurs

• Individual Excellence in Engineering Enterprises

Postal rates for 'light letters' are 25p up to 10g, 35p up to 50g plus an extra 10p for each additional 25g up to 100g. Which test inputs (in grams) would be selected using equivalence partitioning?

• 8, 42, 82, 102

• 4, 15, 65, 92, 159

• 10, 50, 75, 100

• 5, 20, 40, 60, 80

Which of the following is a form of functional testing?

• Boundary value analysis

• Usability testing

• Performance testing

• Security testing

Equivalence partitioning consists of various activities:

• Ensure that test cases test each input and output equivalence class at least once

• Identify all inputs and all outputs

• Identify equivalence classes for each input

• All of the above

In which order should tests be run?

• The most important tests first

• The most difficult tests first(to allow maximum time for fixing)

• The easiest tests first (to give initial confidence)

• The order they are thought of

A program validates a numeric field 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 covers the MOST boundary values?

• 9,10,11,22

• 9,10,21,22

• 10,11,21,22

• 10,11,20,21
