2. Which of the following techniques are black box techniques?

a. State transition testing, code testing, agile testing

b. Equivalence partitioning, state transition testing, decision table testing

c. System testing, acceptance testing, equivalence partitioning

d. System integration testing, system testing, decision table testing

3. A defect management system shall keep track of the status of every defect registered and enforce the rules about changing these states. If your task is to test the status tracking, which method would be best?

a. Logic-based testing

b. Use-case-based testing

c. State transition testing

d. Systematic testing according to the V-model

4. If a program is tested and 100% condition coverage is achieved, which of the following coverage criteria is then guaranteed to be achieved?

a. 100% branch coverage

b. 100% condition coverage and 100% statement coverage

c. Equivalence class and boundary value coverage

d. No other white box coverage criterion is guaranteed to be fulfilled 100%

5. This part of a program is given:

WHILE (condition A) Do B END WHILE

How many decisions should be tested in this code in order to achieve 100% decision coverage?

a. 2

b. Indefinite

c. 1

d. 4

6. Why can be tester dependent on configuration management?

a. Because configuration management assures that we know the exact version of the testware and the test object

b. Because test execution is not allowed to proceed without the consent of the change control board

c. Because changes in the test object are always subject to configuration management

d. Because configuration management assures the right configuration of the test tools

7. What test items should be put under configuration management?

a. The test object, the test material and the test environment

b. The problem reports and the test material

c. Only the test object. The test cases need to be adapted during agile testing

d. The test object and the test material

8. Why is successful test execution automation difficult?

a. Because the tools for automated testing require too much effort for learning

b. Because the maintenance of the test system is difficult

c. Because the test robot tools are restricted in their ability to recognize outputs

d. Because the test robot needs to be supported by a test management.

9. Which of the following can be root cause of a bug in a software product?

(I) The project had incomplete procedures for configuration management.

(II) The time schedule to develop a certain component was cut.

 (III) the specification was unclear

(IV) Use of the code standard was not followed up

(V) The testers were not certified

a. (I) and (II) are correct

b. (I) through (IV) are correct

c. (III) through (V) are correct

d. (I), (II) and (IV) are correct

10. Which of the following is most often considered as components interface bug?

a. For two components exchanging data, one component used metric units, the other one used British units

b. The system is difficult to use due to a too complicated terminal input structure

c. The messages for user input errors are misleading and not helpful for understanding the input error cause

d. Under high load, the system does not provide enough open ports to connect to

11. Which of the following project inputs influence testing?

 (I) contractual requirements

(II) legal requirements

(III) Industry standards

(IV) application risk

(V) project size

a. (I) through (III) are correct

b. All alternatives are correct

c. (II) and (V) are correct

d. (I), (III) and (V) are correct

12. If a program is tested and 100% branch coverage is achieved, which of the following coverage criteria is then guaranteed to be achieved?

a. 100% Equivalence class coverage

b. 100% Condition coverage and 100% Statement coverage

c. 100% Statement coverage

d. 100% Multiple condition coverage

13. This part of a program is given:

WHILE (condition A) Do B END WHILE

How many paths should be tested in this code in order to achieve 100% path coverage?

a. One

b. Indefinite

c. Two

d. Four

14. What is the purpose of test exit criteria in the test plan?

a. To specify when to stop the testing activity

b. To set the criteria used in generating test inputs

c. To ensure that the test case specification is completed. To know when a specific test has finished its execution

15. Which of the following items need not to be given in an incident report?

a. The version number of the test object

b. Test data and used environment

c. Identification of the test case that failed

d. The location and instructions on how to correct the fault

16. V-Model is:

a. A software development model that illustrates how testing activities integrate with software development phases

b. A software life-cycle model that is not relevant for testing

c. The official software development and testing life-cycle model of ISTQB

d. A testing life cycle model including unit, integration, system and acceptance phases

17. Why is incremental integration preferred over “big bang” integration?

a. Because incremental integration has better early defects screening and isolation ability

b. Because “big bang” integration is suitable only for real-time applications

c. Incremental integration is preferred over “Big Bang Integration” only for “bottom up” development model

d. Because incremental integration can compensate for weak and inadequate component testing

18. Maintenance testing is:

a. Testing management

b. Synonym of testing the quality of service

c. Triggered by modifications, migration or retirement of existing software

d. Testing the level of maintenance by the vendor

19. A test engineer is testing a Video Player (VCR), and logs the following report:

Title: Fast Forward stops after 2 minutes. It happens every time

Expected result: Fast forward continues till the end of the tape

Severity: High

Priority: Urgent

What important information did the engineer leave out?

a. Identification (Software and hardware) of the VCR

b. Actual result

c. History of the report

d. Ideas for the test case improvement

20. Why is it necessary to define a Test Strategy?

a. As there are many different ways to test software, thought must be given to deciding what will be the most effective way to test the project on hand.

b. Starting testing without prior planning leads to chaotic and inefficient test project

c. A strategy is needed to inform the project management how the test team will schedule the test-cycles

d. Software failure may cause loss of money, time, business reputation, and in extreme cases injury and death. It is therefore critical to have a proper test strategy in place.
