CTFL 2018 Sample Exam D

1. A system calculates the bonus for airplane pilots.

The business rules R1–R5 for admitting the bonus are presented in the following decision table.

Which of the following sets of test inputs is a minimal set that achieves the equivalence partitioning coverage for the output value? Assume each test input is a pair (s, f ), where s denotes the simulator hours and f—flight hours.

2. Which of the following is true of the V-model?

3. You are responsible for the functional testing of the new mobile application for tourists.

The application allows a user to plan a route, modify it, read info about the monuments, etc. All these functional requirements are documented in the form of use cases. Together with your team, you are planning to perform a review of the application regarding its functionality. Which review type will probably be the most beneficial in this case?

4. Put the test cases that implement the following test conditions into the best order for the test execution schedule, for a test that is checking modifications of customers on a database.

1. Print modified customer record.
2. Change customer address: house number and street name.
3. Capture and print the on-screen error message.
4. Change customer address: postal code.
5. Confirm existing customer is on the database by opening that record.

6. Which of the following is an organizational success factor for reviews?

7. Which of the following is the most important difference between the metrics-based approach and the expert-based approach to test estimation?

9. A test plan included the following clauses among the exit criteria:

# System test shall continue until all significant product risks have been covered to the extent specified in the product risk analysis document.

# System test shall continue until no must-fix defects remain against any significant product risks specified in the product risk analysis document.

During test execution, the test team detects 430 must-fix defects prior to release and all must-fix defects are resolved. After release, the customers find 212 new defects, none of which were detected during testing. This means that only 67% of the important defects were found prior to release, a percentage which is well below average in your industry. You are asked to find the root cause for the high number of field failures. Consider the following list of explanations:

I. Not all the tests planned for the significant product risks were executed.

II. The organization has unrealistic expectations of the percentage of defects that testing can find.

III. A version-control issue has resulted in the release of a version of the software that was used during early testing.

IV. The product risk analysis failed to identify all the important risks from a customer point of view.

V. The product risk analysis was not updated during the project as new information became available.

Which of the following statements indicate which explanations are possible root causes?

10. How do experience-based techniques differ from black box techniques?

11. Consider the following excerpt of a document:
