A team is about to release a new version of a web application. The release includes a fix for a critical security vulnerability in the login module and a minor UI change to the dashboard. The team has a regression suite with tests for all modules. What should be the primary factor in determining the regression scope?

The number of test cases in the suite.

The risk associated with the login module fix and its potential impact on other modules.

The time available for regression testing.

The number of new features in the release.

A team has an automated regression suite that is not fully maintained. Some tests are flaky and fail intermittently. The team is planning regression for a release that changes the inventory management module. The change is considered high risk. What is the best approach to regression testing?

Only run manual tests for the inventory module, since the automated suite is unreliable.

Run the full automated suite and ignore the flaky tests, since automation is the most efficient way.

Perform a thorough impact analysis of the change, then select a mix of automated and manual tests for the affected modules and their dependencies.

Defer regression testing until the automated suite is fully maintained.

When considering test automation for regression testing, what is a significant cost factor to evaluate?

The cost of writing test documentation

The cost of maintaining automated test scripts as the application evolves

The cost of purchasing test management tools

The cost of training testers on manual testing techniques

What is a key benefit of using automated regression tests when determining regression scope?

They require no maintenance when the application changes

They allow a larger set of regression tests to be executed quickly and repeatedly

They guarantee that all defects will be found

They eliminate the need for manual testing entirely

A defect fix modifies the calculation logic in the billing module. Which existing system area is most likely to be impacted and should be included in regression testing?

The user interface of the login screen

The system's backup and recovery procedures

The reporting module that uses billing data

The password reset functionality

Determining the Scope of Regression Testing CTAL-TA Practice Questions (Page 1)

Part of the The Tasks of the Test Analyst in Risk-Based Testing domain, which makes up ~12% of our current practice bank. ISTQB does not publish an official question count, but from its 120-minute exam (~50–80 total, ~6–10 in this domain), expect 3–5 from this objective — we provide 24 practice questions to prepare you well beyond it.
