   According to the test pyramid, how should test effort be distributed across different test levels?

   • AMost effort on end-to-end tests, with fewer unit tests
   • BEqual effort on unit, integration, and end-to-end tests
   • CAll effort on integration tests to verify interfaces
   • DMost effort on unit tests, fewer integration tests, and the fewest end-to-end tests

   A team has a test suite with 500 unit tests, 100 integration tests, and 50 end-to-end tests. They have only enough time to run 200 tests before the release. According to the test pyramid, which tests should be prioritized for execution?

   • ARun all 500 unit tests, because they are the fastest and most numerous, and skip the integration and end-to-end tests.
   • BRun 100 unit tests, 50 integration tests, and 50 end-to-end tests, because this balances the three layers equally.
   • CRun all 50 end-to-end tests and 150 integration tests, because they cover the most user-visible functionality.
   • DRun 150 unit tests, 40 integration tests, and 10 end-to-end tests, proportionally to the pyramid's distribution.

   A team is planning the execution of a regression test suite for a web application. The release includes a new payment integration and a change to the user profile page. The team has limited time and must decide which tests to run first. Which prioritization criterion is most appropriate for this scenario?

   • ARun tests alphabetically by test name, because this ensures all test areas are covered evenly.
   • BRun tests that cover the payment integration first, because it is a new feature with high business risk.
   • CRun tests in the order they were written, because this preserves the original test design intent.
   • DRun tests that are fastest to execute first, because this maximizes the number of tests run in the available time.

   A team is building a new application and has written a large number of unit tests, a moderate number of integration tests, and a few end-to-end tests. The test pyramid is well-balanced. However, the team is now facing a tight release deadline and must reduce the test execution time. Which action is the most effective while preserving the pyramid's balance?

   • ARemove the end-to-end tests from the CI pipeline and run them only before the release.
   • BReduce the number of unit tests, because they are the least valuable for catching defects.
   • CIncrease the number of end-to-end tests to cover more user journeys, because they provide the most confidence.
   • DRun the tests in parallel to reduce the overall execution time without changing the test distribution.

   A test manager has limited time to execute the test suite before release. Which approach best applies test case prioritization?

   • AExecute test cases randomly to avoid bias in test selection.
   • BExecute only the test cases that are automated to save time.
   • CExecute test cases in the order they were written to maintain traceability.
   • DExecute test cases based on the likelihood of finding defects and the impact of the features they cover.
