Which practice is important for effective regression test automation?

Writing tests that are independent and can run in any order

Hard-coding test data to ensure stability

Writing tests that depend on the execution of previous tests

Running automated tests only at the end of the project

Why is regression test maintenance important in an Agile project?

To ensure tests are written in a specific programming language

To reduce the number of testers needed

To keep the test suite aligned with the evolving system and requirements

A team maintains a regression suite for a web application. After a recent feature change, several test cases are no longer valid because the UI flow has changed. The team needs to keep the suite relevant. What is the best course of action?

Replace the entire suite with new tests written from scratch.

Update the test cases to reflect the new UI flow and verify they still test the intended functionality.

Keep the old test cases and mark them as 'known to fail'.

Delete the obsolete test cases immediately to keep the suite clean.

A team has a regression suite that includes tests for both new features and existing functionality. They want to ensure that new features do not break existing functionality. What is the best way to prioritize regression tests?

Run only the tests for existing functionality.

Run tests for existing functionality first, then tests for new features.

Run tests for new features first, then existing functionality.

A team is about to release a new version of an e-commerce application. The change is limited to the payment processing module, specifically the tax calculation logic. The regression test suite has 500 test cases, but the team has only a 4-hour window to run regression tests before the release. The test lead needs to decide which tests to run and in what order. What is the most appropriate approach?

Run only the tests that directly test tax calculation and payment processing, in the order they appear in the suite.

Perform impact analysis to identify tests affected by the tax logic change, then run those tests first, followed by other high-risk tests if time permits.

Run all 500 tests in the existing order, starting with the oldest tests first.

Run only the new tests added for the tax change, assuming existing tests are still valid.
