Deleting tests that are no longer relevant to the current sprint

What is the purpose of impact analysis in the context of regression testing?

To decide whether to automate or manually run tests

To determine which parts of the system are affected by a change

To estimate the cost of the entire regression test suite

To measure the performance of the system after a change

Upgrade the library and run the full regression suite.

What is a key benefit of automating regression tests in an Agile team?

It eliminates the need for manual testing entirely

It allows the team to run the regression suite frequently and consistently

It reduces the need for test maintenance
