   A team has a regression suite with tests that cover different risk areas. Some tests are for critical business functions, while others are for low-risk features. The team has limited time for regression testing. How should they prioritize the tests?

   • ARun tests in alphabetical order to be fair.
   • BRun the longest tests first to get them out of the way.
   • CRun tests for critical business functions first, then lower-risk tests if time permits.
   • DRun the shortest tests first to maximize the number of tests run.

   An agile team has a regression suite of 200 automated tests. They have a CI pipeline that runs the full suite on every commit, but the suite takes 45 minutes, which slows down feedback. The team wants to reduce feedback time while still catching regressions early. Which approach best balances speed and coverage?

   • ARun the full suite only on nightly builds, and run a smoke test on every commit.
   • BRun all tests in parallel on multiple agents to reduce wall-clock time.
   • CPrioritize tests based on risk and run the top 20% on every commit, with the full suite on merge to main.
   • DRemove all tests that take longer than 5 seconds to keep the suite fast.
