Technical Fundamentals
Q: What is software testing?
A: The process of evaluating software to identify defects and ensure it meets specified requirements and quality standards.
Q: What is the difference between manual testing and automation testing?
A: Manual testing is human-driven test execution; automation uses scripts and tools to run repeatable tests faster and more reliably.
Q: What is the software testing life cycle (STLC)?
A: STLC includes phases like requirement analysis, test planning, test case design, environment setup, test execution, and closure.
Q: What is the difference between SDLC and STLC?
A: SDLC covers full software development steps; STLC focuses specifically on the testing activities within that lifecycle.
Q: What is a test case and how do you write one?
A: A test case defines inputs, steps, expected results, and prerequisites; write clear titles, preconditions, steps, and expected outcomes.
Q: What is a test plan and why is it important?
A: A test plan outlines scope, objectives, approach, resources, schedule, and risks — it aligns stakeholders and guides testing effort.
Test Design & Management
Q: What is a test strategy?
A: A high-level document defining testing scope, objectives, resource allocation, tools, and types of testing to be used.
Q: What is traceability matrix (RTM)?
A: A matrix mapping requirements to test cases to ensure full coverage and track statuses through testing.
Q: What is boundary value analysis?
A: A design technique testing at values on, just below, and just above input boundaries to find edge-case defects.
Q: What is equivalence partitioning?
A: Dividing input data into valid/invalid partitions so representatives from each partition are tested to reduce cases.
Q: How do you decide when to stop testing?
A: Stop when exit criteria (coverage, critical bug fixes, time constraints) are met, and risk is acceptable after sign-off.
Q: What is regression testing and when is it run?
A: Regression retests to ensure changes don’t break existing features; run after bug fixes, new builds, or releases.
Bug Reporting & Lifecycle
Q: What is a defect life cycle?
A: Stages include New, Assigned, Open, Fixed, Retest, Verified, Closed, Reopened — tracking a defect’s progress.
Q: How do you prioritize severity vs priority?
A: Severity measures technical impact; priority indicates business fix order. A low-severity issue can be high priority.
Q: What is defect leakage?
A: Defects missed during testing that appear in production; analyze root cause and improve test coverage to prevent leakage.
Q: What fields are essential in a bug report?
A: Summary, steps to reproduce, environment, expected vs actual result, severity, priority, screenshots/logs, and build/version.
Q: How do you measure testing effectiveness?
A: Use metrics like defect density, test coverage, pass/fail rates, escaped defects, and mean time to detect/fix.
Automation & Tools
Q: What factors determine whether to automate a test?
A: Repeatability, criticality, stability of the feature, ROI, and execution frequency drive automation decisions.
Q: What is Selenium and when would you use it?
A: Selenium is an open-source browser automation tool for web UI tests; use it for cross-browser regression suites.
Q: What is a test automation framework?
A: A set of guidelines, tools, and libraries (e.g., data-driven, keyword-driven, BDD) that structure and standardize automation.
Q: How do you validate APIs in testing?
A: Use tools like Postman/Rest Assured to test endpoints, validate responses, status codes, headers, data, and error handling.
Q: What is CI/CD in testing?
A: Continuous Integration/Delivery integrates code frequently and runs automated tests to catch issues early and support fast releases.
Scenario-Based & Behavioral
Q: Describe a time you found a critical bug close to release.
A: Summarize the issue, steps taken to reproduce, communication with stakeholders, testing to confirm fix, and release impact.
Q: How do you handle conflicting feedback from devs and product owners?
A: Clarify requirements, provide evidence (logs/screenshots), prioritize based on impact, and suggest mitigations until resolved.
Q: How do you test a feature with incomplete requirements?
A: Ask clarifying questions, create exploratory tests based on assumptions, document risks, and request formal acceptance criteria.
Q: What is exploratory testing and when is it useful?
A: Simultaneous learning, test design, and execution; great for early phases, new features, and investigating complex systems.
Q: How do you communicate test results to non-technical stakeholders?
A: Summarize impact, use visuals and metrics, recommend actions, and relate defects to business risk and timelines.
