Testing, Quality & Reliability Topics

Quality assurance, testing methodologies, test automation, and reliability engineering. Includes QA frameworks, accessibility testing, quality metrics, and incident response from a reliability/engineering perspective. Covers testing strategies, risk-based testing, test case development, UAT, and quality transformations. Excludes operational incident management at scale (see 'Enterprise Operations & Incident Management').

Real World Problem Solving and Edge Cases

Ability to solve practical problems that come up during automation implementation. Handling edge cases, dealing with application quirks, managing timing issues, dealing with dynamic content, and finding pragmatic solutions. Thinking through the entire test execution flow and potential failure modes.

0 questions

Exploratory and Manual Testing

Focus on when and how to use manual exploratory testing to discover issues that automation can miss and how to integrate those findings into the overall quality strategy. Topics include session based testing and time boxed charters, heuristics and exploratory techniques for finding edge cases and error conditions, multi step and stateful user journeys, documenting and reproducing defects with clear steps expected versus actual results severity and impact, triage and prioritization with product and engineering, and converting high value exploratory discoveries into automated regression tests when appropriate.

0 questions

Testing Strategy and Continuous Improvement

Covers high level strategic thinking about testing and how testing practices evolve over time. Topics include defining testing philosophy and strategy beyond individual frameworks or tools, test coverage planning, trade offs between test types, integrating testing into development lifecycle, establishing metrics for test effectiveness, and driving organization wide continuous improvement of testing practices and quality engineering processes.

0 questions

Testing Related Problem Solving

Solve problems in contexts adjacent to software testing and validation, such as generating test data combinations, designing validation logic for API responses, detecting anomalies in test results, or writing small algorithmic solutions that support quality assurance. Assess systematic thinking about edge cases, combinatorial test coverage, input generation strategies, and pragmatic trade offs between exhaustive testing and practicality. Expect short technical exercises or algorithmic prompts framed as testing tasks that evaluate coding clarity, correctness, and test oriented reasoning.

Test Automation Framework Architecture and Design

Design and architecture of test automation frameworks and the design patterns used to make them maintainable, extensible, and scalable across teams and applications. Topics include framework types such as modular and structured frameworks, data driven frameworks, keyword driven frameworks, hybrid approaches, and behavior driven development style organization. Core architectural principles covered are separation of concerns, layering, componentization, platform abstraction, reusability, maintainability, extensibility, and scalability. Framework components include test runners, adapters, element locators or selectors, action and interaction layers, test flow and assertion layers, utilities, reporting and logging, fixture and environment management, test data management, configuration management, artifact storage and versioning, and integration points for continuous integration and continuous delivery pipelines. Design for large scale and multi team usage encompasses abstraction layers, reusable libraries, configuration strategies, support for multiple test types such as user interface tests, application programming interface tests, and performance tests, and approaches that enable non automation experts to write or maintain tests. Architectural concerns for performance and reliability include parallel and distributed execution, cloud or container based runners, orchestration and resource management, flaky test mitigation techniques, retry strategies, robust waiting and synchronization, observability with logging and metrics, test selection and test impact analysis, and branching and release strategies for test artifacts. Design patterns such as the Page Object Model, Screenplay pattern, Factory pattern, Singleton pattern, Builder pattern, Strategy pattern, and Dependency Injection are emphasized, with guidance on trade offs, when to apply each pattern, how patterns interact, anti patterns to avoid, and concrete refactoring examples. Governance and process topics include shared libraries and contribution patterns, code review standards, onboarding documentation, metrics to measure return on investment for automation, and strategies to keep maintenance costs low while scaling to hundreds or thousands of tests.

Collaboration with Development Teams on Quality Issues

Be prepared to discuss how you work with developers when reporting bugs, verifying fixes, and discussing quality improvements. Explain how you communicate effectively with non-QA team members, ask clarifying questions about expected behavior, and work together to ensure quality standards are met. Share an example of a time you collaborated with a developer to understand a complex issue or verify a fix.

0 questions

Test Scenario Identification and Analysis

Ability to derive comprehensive and prioritized test scenarios from feature descriptions or requirements. Includes identification of positive paths, negative paths, boundary and edge cases, error conditions, and performance or security related scenarios. Covers risk based prioritization, test case design techniques, and how to document scenarios so they are actionable for manual or automated testing.

0 questions

Performance and Load Testing

Covers design and execution of tests that measure how software behaves under varying levels of user concurrency and resource demand, including load testing, stress testing, soak testing, and spike testing. Includes key performance metrics such as response time, throughput, latency, error rates, and resource utilization and how to collect and interpret these signals. Explains common tooling and approaches for load generation and results analysis, for example JMeter, Gatling, and LoadRunner, and how to instrument systems for monitoring and tracing. Addresses testing at scale, including distributed load generation, test environment configuration, test data management, and identifying and diagnosing performance bottlenecks across application, database, and infrastructure layers. Describes how to integrate performance testing into the development lifecycle and continuous integration and continuous delivery pipelines, how to report findings and performance regressions to stakeholders, and how functional correctness concerns interact with performance objectives.

Test Automation Levels

Covers the testing pyramid and the roles of different automated test types: unit tests for fast isolated verification of individual components, integration tests for validating interactions between multiple components, system tests for end to end verification of a complete deployed system, and acceptance tests for confirming that the system meets user requirements. Includes trade offs in distribution and cost of tests, strategies for test data management and environment provisioning, when to use mocks or stubs, approaches to reduce flakiness, metrics for test coverage and effectiveness, maintaining fast feedback loops in continuous integration pipelines, and selecting tools and frameworks appropriate to each level.
