ISTQB Certification Exam-Sample Papers

Q. 751: As a test leader you are collecting measures about defects. You recognize that after the first test cycle – covering all requirements - subsystem C has a defect density that is 150% higher than the average. Subsystem A on the other hand has a defect density that is 60% lower than the average.

What conclusions for the next test cycle could you draw from this fact?

 

A. It is probable that subsystem C has still more hidden defects. Therefore we need to test subsystem C in more detail.

 

B. Because we have already found many defects in subsystem C, we should concentrate testing resources n Subsystem A.

 

C. Observed defect density does not allow any conclusions about the amount of additional testing.

 

D. We should try to equalize the amount of testing over all modules to ensure that we test all subsystems evenly.

Q. 752: Which of the following is a TRUE statement about the use of static analysis tools?

 

A. Static analysis tools can change the code to reduce complexity.

B. Static analysis tools are intended to support developers only.

C. Static analysis tools aid in understanding of code structure and dependencies.

D. Static analysis tools cannot be used to enforce coding standards.

Q. 753: Which of the following best describes typical test exit criteria?

 

A. Reliability measures, number of tests written, and product completeness.

 

B. Thoroughness measures, reliability measures, cost, schedule, tester availability and residual risks.

 

C. Thoroughness measures, reliability measures, test cost, amount of time spent testing and product completeness, number of defects.

 

D. Time to market, residual defects, tester qualification, degree of tester independence, thoroughness measures and test cost.

Q. 754: How does testing contribute to software quality?

 

A. Testing ensures that the system under test will not error out in a production environment.

B. Testing identifies defects which ensures a successful product will be released to market.

C. Testing increases the quality of a software system by avoiding defects in the system under test.

D. Testing through verification and validation of functionality identifies defects in the system under test.

Q. 755: A company is going to provide their employees with a bonus which will be based on the employee's length of service in the company. The bonus calculation will be zero if they have been with the company for less than two years, 10% of their salary for more than two but less than five years, and 25% for five to ten years, 35% for ten years or more. The interface will not allow a negative value to be input, but it will allow a zero to be input.

 

How many equivalence partitions are needed to test the calculation of the bonus?

 

A. Two equivalence partitions.

B. Three equivalence partitions.

C. Four equivalence partitions.

D. Five equivalence partitions.

Q. 756: Which of the statements about reviews are correct?

 

I. Reviews are useful because, through their use, defects can be found early, resulting in cost savings.

II. Reviews are useful because they help management understand the comparative skills of different developers.

III. Testers should not get involved in specification reviews because it can bias them unfavorably.

IV. Many early defects are found in reviews, lengthening the time needed for the development life cycle

 

A. I

B. IV

C. I and IV

D. I and III

Q. 757: What is integration testing?

 

A. Integration of automated software test suites with the application under test.

B. Testing performed to expose faults in the interaction between components and systems.

C. Testing to verify that a component is ready for integration with the rest of the system.

D. Testing to verify that the test environment can be integrated with the product.

Q. 758: Below you find a list of descriptions of problems that can be observed during testing or operation. Which is most likely a failure?

A. The product crashed when the user selected an option in a dialog box.

B. One source code file included in the build was the wrong version

C. The computation algorithm used the wrong input variables.

D. The developer misinterpreted the computational requirement for that algorithm.

Q. 759: Which one of the following describes best the difference between testing

and debugging?

 

A. Testing shows failures that are caused by defects. Debugging finds, analyzes, and removes the causes of failures in the software.

B. Testing pinpoints the defects. De bugging analyzes the faults and proposes preventing activities.

C. Testing removes faults. Debugging identifies the causes of failures.

D. Dynamic testing prevents causes of failures. Debugging removes the failures.

Q. 760: Which of the following is a good reason for a developer to use a Test Harness tool?

 

A. To help the developer to compare differences between files and databases.

B. To reduce the quantity of component tests needed to be run.

C. To make it easier for developers to peer-test each other's code.

D. To simplify running unit tests when related components are not available yet.
