CTAL-ATT Exam Dumps : Certified Tester Advanced Level Agile Technical Tester

Service Virtualization in Agile:Virtualized services are ideal for simulating unavailable components, enabling comprehensive testing without waiting for the actual service to be developed.

Minimizing Extra Work:Using a service virtualization tool reduces the need for manual creation and maintenance of stubs or other temporary solutions.

Analysis of Options:

A is impractical, as testers should not develop production services.

B is less efficient than service virtualization and requires ongoing setup/teardown.

C provides an efficient and reusable solution.

D risks misalignment with the new system.

Conclusion:Option C is the best approach for agile test automation progress.

Exploratory Testing and Risk Levels:

Exploratory testing is a flexible approach that involves simultaneous test design and execution, making it highly valuable across all risk levels.

For high-risk systems, exploratory testing is essential as it uncovers critical issues efficiently.

For medium- and low-risk systems, it is equally beneficial for identifying functional and usability defects, especially when formal test cases may not cover all scenarios.

Analyzing the Options:

A and B: These fail to emphasize the importance of exploratory testing for high-risk systems.

D: States that exploratory testing is "not recommended" for high-risk systems, which is inaccurate.

C: Correctly states that exploratory testing is "highly recommended" across all risk levels, aligning with the ISTQB syllabus guidance.

References:ISTQB Advanced Agile Technical Tester syllabus highlights exploratory testing as a versatile and valuable technique for all risk levels.

A deterministic unit test is one that produces the same results every time it is run under the same conditions. This characteristic is crucial for unit tests because it ensures that the tests are reliable and that their results are repeatable. Deterministic tests help in identifying when a change in the codebase has introduced a defect, as any variation in the test outcome can be attributed to the change rather than an unpredictable test behavior12.
