CTFL-2018 Online Practice Questions and Answers

Which of the following would achieve the HIGHEST level of testing independence for a project's system test level?

A. Training developers to design good tests for the test team to execute.

B. Outsourcing test design and execution to a different company.

C. Having the company's independent test team design and execute the tests.

D. Minimising contact between testers and developers during test design to avoid bias.

When comparing Static and Dynamic test techniques, which of the following statements is TRUE?

A. Static Testing finds failures, whilst Dynamic Testing only finds the cause of failures.

B. Static Testing techniques, such as reviews, can be undertaken before Dynamic Testing, making defects cheaper to remove.

C. Static Testing is based on the execution of code, whist Dynamic Testing relies on examination and analysis.

D. Only Static Testing has the objective of identifying defects.

Which of the following is a key difference between black box and white box test design techniques?

A. Black box techniques use software code to derive test cases, white box techniques do not.

B. White box techniques use functional design specifications to derive test cases, black box techniques do not.

C. White box techniques can measure the extent of code coverage, black box techniques can not.

D. White box techniques derive test cases from models of the software, black box techniques do not.

Which of the following is an approach that can be used for exploratory testing?

A. Time-boxed test sessions are created, during which a tester uses a test charter containing test objectives to guide the testing.

B. A tester methodically executes tests from a list of possible failures, based on experience, defect and failure data.

C. A tester analyses, designs and implements tests based on external rules and standards.

D. Tests are designed based on the guidance of stakeholders and experts outside the test team.

Which of the following BEST describes a methodical approach to the Error Guessing test technique?

A. A tester dynamically designs and executes tests based on their knowledge, to learn more about the system and to create tests for the areas that may need more testing.

B. An experienced tester makes a list of potential defects and failures, based on experience and past defect data. Then designs and runs tests to generate these failures should the defects be present in the code.

C. A tester designs, implements and executes tests to cover test conditions found in checklists that are based on what is important for the user.

D. An inexperienced tester is asked to attempt to guess errors that may have been missed by experienced testers during formal test design.

Testing effort can depend on a number of factors, which one of the following is MOST likely to impact the amount of effort required?

A. The predicted number of defects and the amount of rework required.

B. The ratio of developers to testers in the project team.

C. The planned use of a project management tool to schedule tasks.

D. The responsibilities for testers and developers being clearly defined.

Which of the following would NOT typically be covered in a test summary report?

A. The risks associated with unresolved defects found during testing.

B. Any features of the system that were not tested along with reasons.

C. Whether there is any economic benefit in continuing testing beyond the planned date.

D. An analysis of lessons learned to determine changes for future projects.

What one of the following would be a typical objective of running a pilot project when introducing a new tool into an organization?

A. To establish whether the tool is available for a free trial period (and for how long).

B. To provide training, coaching, and mentoring for users of the tool.

C. To develop a clear set of requirements and objective criteria against which the tool can be evaluated.

D. To evaluate how the tool fits with existing processes and practices, and determining what would need to change.

An airline's frequent flyer's club awards benefits depending on which tier a customer is in. The software must determine which tier to allocate a customer to based on an input value of total Credits Earned to date.

Customers initially join the Silver Tier and remain in that tier for the first 400 Credits Earned. The next 400 Credits Earned moves the customer into the Gold Tier. The next 600 Credits Earned moves the customer into the Platinum Tier. Further Credits Earned moves the customer into the Concierge Tier.

Test Cases have been written with the following total Credits Earned input values: TC1 – 400 Credits TC2 – 500 Credits TC3 – 800 Credits TC4 – 1500 Credits

Applying the Equivalence Partitioning test design technique, what percentage of valid Equivalence Partitions have these 4 test cases collectively achieved?

A. 25%

B. 50%

C. 75%

D. 100%

Which one of the following is an example of how product risk analysis can influence the testing approach?

A. The complex business rules could result in costly failures, so decision table testing will be used for test case design.

B. Performance failures were much lower than expected, so more test analysis will be conducted in this area.

C. There is a lack of automation skills in the test team, so training for the automation tool will be rolled out.

D. There are no product risks recorded around security, so security testing will be given priority as a contingency measure.
