Question 8

The following state diagram is given as basis for state transition testing and contains only valid transitions:

Explanation of the state diagram: States are depicted as nodes. The initial state is I, the final state is F. A state transition is depicted as a directed arrow with the initiating event as a label, e. g. from I to S1 with event a, and is also written as a triple (I,a,S1). Note: A test case is a sequence of events that initiates the corresponding sequence of state transitions.
The state diagram contains the following 7 state transitions:
(I, a, S1)
(S1, a, S2), (S1, b, S3), (S1, c, F)
(S2, a, S3)
(S3, a, S2), (S3, b, F)
What is the minimum number of test cases to achieve 100% coverage of all valid state transitions in the diagram?

A. 3 B. 4 C. 8 D. 2

Correct Answer: B

Question 9

Consider the following list of possible benefits of retrospectives (A to D):

A. A1 - B4 - C3 - D2 B. A2 - B1 - C4 - D3 C. A4 - B3 - C2 - D1 D. A3 - B2 - C1 - D4 E. Better cooperation between development and testing
... and the list of possible characteristics of retrospectives (1 to 4) that enable achieving these benefits:
The possibility of implementing suggestions for process improvement
The opportunity to raise problems and propose points for improvement
The regular review and optimization of the collaboration between team members The possibility of addressing and solving deficiencies in the extent and quality of the requirements Which ONE of the following options presents the BEST mapping between benefits and characteristics from retrospectives? F. Team bonding and learning G. Improved quality of the test basis H. Increased test effectiveness/efficiency

Question 10

Which of the following BEST explains a drawback of independent testing?

A. Due to their differing backgrounds and perspectives, an independent test team may discover defects which the developers did not uncover B. An independent test team may possess specializations in specific test types such as usability or security which detract from the overall effectiveness of the test team C. An independent test team may be isolated from the rest of the development and project team D. Having the business organization participate as an independent test team can hurt the overall testing effort since business participants are often not trained nor experienced in testing

Question 11

Which of the following statements about Experience Based Techniques (EBT) is correct?

A. EBT is done as a second stage of testing, after non-experienced-based testing took place. B. EBT require broad and deep knowledge in testing but not necessarily in the application or technological domain. C. EBT use tests derived from the test engineers' previous experience with similar technologies. D. EBT is based on the ability of the test engineer to implement various testing techniques.

Question 14

Which ONE of the following options MOST ACCURATELY describes branch testing?
