ISTQB Foundation Level CTFL

Explore the fundamentals of software testing, including dynamic vs static testing and verification vs validation. Learn the seven objectives of testing to assess quality and reduce risk.

Discover why testing is essential for higher quality, differentiate errors, defects, and failures, and learn how early tester involvement and root-cause analysis improve quality management.

Explore the seven principles of testing, including why testing finds defects, why exhaustive testing is impossible, early testing saves time, defect clustering, pesticide paradox, and context-dependent testing.

Explore the seven test process activities—planning, monitoring and control, analysis, design, implementation, execution, and completion—and their work products, with emphasis on traceability to the test basis and coverage criteria.

Discover how confirmation bias and other cognitive biases shape how defects are received. Learn to communicate defect information constructively to reduce tensions and align testers, analysts, and developers toward quality.

Explain the relationships between development and testing activities across the software lifecycle and why models must be adapted to project and product characteristics, including common lifecycle models and early testing.

Examine the four test levels—component, integration, system, and acceptance—and their objectives, test bases, test objects, and responsibilities, using an e commerce example and noting continuous integration and automated testing.

Explore functional, non-functional, and white-box testing across all test levels, and learn how confirmation and regression testing verify fixes and detect unintended changes.

Explore maintenance testing by identifying modification triggers, environment changes, migrations, and retirements, and apply impact analysis to assess consequences and regression risks.

Explore static testing basics by examining specifications, architecture and design specifications, and code through reviews and static analysis; compare with dynamic testing and highlight early defect detection and cost savings.

Explore the ISTQB foundation level CTFL review process in software development, covering planning, initiation, and defect detection through informal, technical, and inspection reviews, plus success factors and roles.

Explore black box, white box, and experience based test techniques and how to choose and apply them to identify test conditions, cases, and data.

Explore black-box test techniques, including equivalence partitioning, boundary value analysis, decision table testing, state transition testing, and use-case driven test case derivation from requirements.

Explore white-box test techniques, focusing on statement and decision coverage, how each measures code testing progress, and why 100% decision coverage guarantees 100% statement coverage but not vice versa.

Explore experience-based test techniques, including error guessing, exploratory testing, and checklist-based testing, driven by tester skills, intuition, and past projects to uncover unseen defects.

Understand test organization and independence in testing, including benefits and drawbacks of independent testing. Learn the tasks of test managers and testers, and how agile and cross-functional teams implement testing.

Plan and organize testing by defining the test plan's purpose, content, and entry and exit criteria. Prioritize test cases, manage dependencies, and estimate effort using metrics-based or expert-based techniques.

Learn to monitor and control testing with metrics and test reports, guiding reprioritization, schedule changes, and decisions to meet exit criteria, risk coverage, and agile goals.

Implement configuration management to maintain the integrity of test items and related components throughout the project lifecycle by uniquely identifying, version controlling, and tracing changes.

Define risk levels by likelihood and impact, distinguish product risks from project risks, and use product risk analysis to guide test planning and risk-based testing.

Log defects found during testing and track them through a defined defect management workflow. Create clear defect reports with reproducible steps and environment details to enable resolution.

Classify test tools by purpose and testing activities, from test execution to data preparation and reporting. Identify benefits and risks of automation, and explore data-driven, keyword-driven, and model-based approaches.

Identify principles for selecting test tools, use pilot projects and proof-of-concept evaluations to validate fit and cost, and apply success factors for evaluation, deployment, and ongoing support within software lifecycle.
