Explore how test analysts manage work products, including test cases, environments, data, and scripts, across seven tasks from high- and low-level tests to keyword-driven testing and management tools.

Learn the difference between high-level and low-level test cases, their abstract to concrete evolution, their design-to-implementation relationship, and boundary value analysis as an example of testing transitions.

Ensure every test case meets the nine quality criteria: correctness, feasibility, necessity, understandability, traceability, consistency, precision, completeness, and conciseness, and is executable, non-duplicative, and decomposed into smaller, easier-to-understand cases.

Assess the quality criteria for test cases and emphasize feasibility. Propose feasible test scenarios, such as 100 concurrent logins with ramping in JMeter, replacing exhaustive date-time combinations with key scenarios.

Build a robust, predictable test environment that enables defect detection, supports automatic test data resets, logs root causes, and delivers consistent results, while integrating with test automation frameworks.

Define test environment requirements during test design by analyzing test conditions, test data, and test levels. Balance fidelity to production with flexibility, using stubs or drivers and ensuring traceability.

Review a sample environment requirements document for testing an e-commerce payment feature, detailing test data, a test database, a test email server, DevOps responsibilities, and backup, restore, and ci/cd readiness.

Explore how to identify and implement test oracles—pseudo-oracles, model-based testing, property-based testing, metamorphic testing, and human oracles—alongside automated and defensive assertions and test bases.

Keyword-driven testing lets a test analyst write tests using business keywords. It organizes keywords into domain and test interface layers with atomic and composite forms for reusable, maintainable low-code automation.

Identify and assess risks through risk identification and categorization, guided by ISO IEC 25010 quality characteristics. The test analyst uses shift-left approaches and stakeholder interviews to plan mitigations and testing.

Describe the tasks of a test analyst in risk-based testing, focusing on risk analysis (identification and assessment) and risk control (monitoring of risks).

Explore chapter three's advanced test techniques for daily software testing, from checklist-based and behavior-based testing to crowd, combinatorial, domain, metamorphic, and decision-table approaches for higher coverage.

Apply combinatorial testing, including pairwise testing, to reveal interaction failures by exploring combinations of configuration parameters and input data values. Leverage Bayes coverage and equivalence partitioning to manage test space.

Apply pairwise testing to manage large input parameter spaces, using equivalence partitioning and boundary value analysis alongside classification trees to generate test cases and capture parameter value pairs.

Apply pairwise testing to cover all value pairs efficiently. Demonstrate how four-value factors yield 16 test cases for insurance options and nine for language, browser, and operating systems.

Learn state-transition testing: how systems move between states via valid and invalid transitions, using guards, state diagrams, and 0-switch to 1-switch coverage.

Explore state-transition testing concepts, including valid transitions, 0-switch coverage, 1-switch coverage, and round-trip coverage, through practical examples like tv power states, battery charger, and credit card pump systems.

Learn state-transition testing techniques, identify feasible one-switch transitions, and design minimal test cases for round-trip coverage using scheduler and mobile-device state diagrams.

Apply use case testing to model transactional, black box test behavior that reflects real user interactions, including basic flow, alternative flows, and exception handling across system, integration, and acceptance contexts.

Explore use case testing through two questions, analyzing main flow, exceptions, and alternative flows in payment and enrollment scenarios, and determine minimum coverage test cases.

Master decision table testing by modeling rules with conditions and actions, and using limited and extended entry tables with boundary value analysis and equivalence partitioning to design robust test cases.

Explore decision table testing by applying equivalence partitioning and boundary value analysis to create minimal, complete test cases for airline reward travel and speeding fines.

Analyze decision table testing techniques for payment options and mobile download scenarios, identify valid rules, don't-cares, and ensure test suites cover all five decision rules.

Experience-based test techniques rely on tester skill and intuition. They adapt when documentation is scarce and testing time is restricted, but may lack repeatability and formal coverage.

Explore exploratory testing, an experience-based technique that lets testers learn, design, and execute tests in one session with lightweight documentation, test charters, and timeboxing, often in agile environments.

Learn how checklist based testing uses high-level, experience-driven checklists to verify user interface, performance, and acceptance criteria in agile and mobile contexts; assess applicability, maintenance, coverage, and variability in results.
