ISTQB Foundation 2026 | 2.3. Maintenance Testing | Click&Break

Описание: Welcome back to Click&Break!

In this lesson, we explore Maintenance Testing, an important concept that focuses on testing software after it has been deployed to production. Software systems constantly evolve due to bug fixes, enhancements, environment changes, and technology updates, and proper testing ensures that these changes do not introduce new issues.

📌 In this video, we cover:
✔ What is Maintenance Testing?

Maintenance testing refers to the testing performed on an existing operational system after changes are made. These changes may include defect fixes, system upgrades, new features, or infrastructure updates.

✔ Why Maintenance Testing is Important

Learn how maintenance testing helps ensure:

Stability after bug fixes

Compatibility after environment changes

Continued system reliability

Reduced risk when modifying existing systems

✔ Types of Changes that Trigger Maintenance Testing

Examples include:

Corrective maintenance – fixing defects

Adaptive maintenance – adapting to new environments (OS, browsers, hardware)

Perfective maintenance – improving performance or usability

✔ Impact Analysis

Discover how testers identify which parts of the system need to be retested after a change and how impact analysis helps focus testing efforts efficiently.

✔ Regression Risks in Maintenance

Understand why regression testing is critical when modifying existing software and how to protect previously working functionality.

Maintenance testing is a key skill for testers working on long-lived systems, product updates, and production environments.
