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

Given the high risk level and the need for a regression-averse strategy due to potential changes in screen design and functionality, the best test approach would involve a strong emphasis on test automation to ensure that new changes do not break existing functionality. Exploratory testing is neutral as it can be useful but is not the primary focus. Manual black-box testing is recommended to verify that the system meets the requirements from an end-user perspective.

Therefore, the option that aligns with these needs is:

Test Automation: ♦+ (highly recommended)

Exploratory Testing: o (neutral/optional)

(manual) Black-box testing: ♦♦ (recommended)

This corresponds to Option 1, which suggests a heavy reliance on automated testing to manage regression risks efficiently, while still incorporating manual black-box testing to cover user experience aspects.

References = The ISTQB Advanced Level Agile Technical Tester documents and training resources emphasize the importance of test automation in Agile projects, especially when dealing with high-risk levels and the need for regression testing1. Additionally, the resources available at Software Testing Help provide insights into Agile testing strategies and best practices that support such an approach2.

Testing Constraints in CI:The time limitations for test execution and results review necessitate prioritization of tests based on criticality and frequency of code changes.

Efficient Allocation:

High-priority tests should run on each build to catch critical issues early.

Medium-priority tests can be run nightly to balance coverage and time constraints.

Low-priority tests are less critical and can run weekly.

Non-functional tests require the integrated stage environment and should run at a predefined time (e.g., Thursday night before sprint end).

Analysis of Options:

A: Running all tests every night is impractical due to time constraints.

B: Medium-priority tests should be run more frequently than at the end of the sprint.

C: Running all tests on every build is unrealistic given the time and resource limitations.

D: Correct, as it ensures efficient prioritization and scheduling of test sets.

Conclusion:Option D provides the most efficient and effective test execution strategy.

Continuous testing facilitates continuous delivery by ensuring that every change made to the codebase is tested automatically and immediately, which helps in identifying defects as early as possible. Automated testing in the delivery environment is crucial as it validates the success of the delivery process by ensuring that the software operates as expected in the production-like environment before the actual release.
