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.

References = The ISTQB Advanced Level Agile Technical Tester syllabus and study resources emphasize the importance of deterministic behavior in unit tests as part of ensuring test reliability and effectiveness34.

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.

Regression-Averse Test Approach:This approach minimizes risks by ensuring tests remain relevant and effective over time. The key focus is maintaining and enhancing the regression suite to reflect changes in the software.

Continuous Improvement of Tests:Keeping tests updated ensures the test suite is reliable and maintains high coverage. This involves adding tests for new features, removing obsolete tests, and refining existing ones.

Conclusion:Option D is correct because it aligns with the goals of regression-averse approaches.
