Test Case Design and Execution Questions

Covers the end to end process of deriving, documenting, organizing, prioritizing, and executing test cases that verify software behavior against functional and nonfunctional requirements. Candidates should demonstrate requirements analysis and traceability to acceptance criteria, selection and application of formal test design techniques such as equivalence partitioning, boundary value analysis, state transition testing, and decision table testing, and the ability to identify positive, negative, and edge case scenarios including error handling, boundary conditions, data variations, state transitions, and interoperability situations. They should be able to structure individual test cases and whole test suites with clear identifiers, preconditions, setup and teardown steps, concise execution steps, explicit test data, expected results, and postconditions, and to organize tests into coherent suites such as smoke, regression, integration, and system tests while prioritizing by risk and requirement criticality. Execution responsibilities include preparing test environments and test data, running manual and automated tests, recording outcomes and evidence, isolating and rerunning flaky tests, and reporting defects with reproducible steps, environment details, expected versus actual behavior, and supporting logs or artifacts. Candidates should also reason about test coverage and tradeoffs, estimate execution effort and runtime, plan regression runs and test selection, design tests for automation readiness through parameterization and modularization, and apply best practices for test data management and maintainability of test artifacts within continuous integration and continuous delivery pipelines. Metrics and considerations such as test effectiveness, maintenance cost, regression strategy, and clear defect reproduction are also in scope.
