   What is a key characteristic of a maintainable automated test suite?

   • ATests are written by a single person to maintain consistency
   • BTests use hard-coded data to ensure consistency
   • CTests are independent and do not depend on execution order
   • DTests are written in a single large file for easy access

   A team is developing a new feature that involves multiple microservices. They have a CI pipeline that runs unit tests in 5 minutes and integration tests in 20 minutes. They want to add end-to-end tests that take 40 minutes. The team values fast feedback but also wants to catch integration issues early. Which strategy best balances these concerns?

   • ARun end-to-end tests on every commit and unit tests only before release.
   • BRun only unit tests on every commit and run integration and end-to-end tests nightly.
   • CRun unit tests on every commit, integration tests on every merge to the main branch, and end-to-end tests only before release.
   • DRun all three test levels on every commit, even if it takes over an hour.

   A company is updating its customer relationship management (CRM) system. The change modifies the data migration process, which is critical and complex. The regression test suite includes tests for data integrity, user interface, and reporting. To minimize regression risk, which tests should be prioritized?

   • ATests that verify data integrity and the migration process, since these are directly affected and high-risk.
   • BAll tests equally, to ensure no area is overlooked.
   • CTests that cover the user interface, since UI changes are most visible to users.
   • DTests that cover reporting, since reports are used by management for decision-making.

   A company wants to prevent regressions from reaching production. They have a CI pipeline that builds the application and runs unit tests on every commit. They want to add automated regression tests to the pipeline. Which integration approach provides the fastest feedback while minimizing pipeline disruption?

   • ARun the full regression suite on a separate machine after the build, but do not block the pipeline on results.
   • BRun a small, fast subset of critical regression tests on every commit, and run the full regression suite nightly.
   • CRun the full regression suite only before each release, and skip it during development.
   • DRun the full regression suite on every commit, even if it takes several hours.
