   A team uses a CI tool that is configured to run a build and unit tests on every commit. The team wants to add a step that deploys the build to a test environment and runs end-to-end tests. However, the end-to-end tests require a specific database configuration that is not available in the CI environment. Which approach is most effective?

   • AProvision the required database configuration as part of the CI pipeline, using scripts or containers.
   • BSkip the end-to-end tests in CI and rely on the staging environment for final verification.
   • CRun the end-to-end tests manually in the test environment after the CI build succeeds.
   • DUse a different CI tool that supports the required database configuration out of the box.

   A team has a CI pipeline that runs unit tests and integration tests. The integration tests take 30 minutes and often fail due to environment issues, not code defects. Developers have started to ignore the integration test results because they are unreliable. The team wants to maintain the benefits of CI while addressing the reliability issue. Which approach is most effective?

   • AFix the environment issues in the test infrastructure so that integration tests run reliably, and keep them in the CI pipeline.
   • BRemove the integration tests from the CI pipeline and rely on manual testing in staging.
   • CMove the integration tests to a separate nightly pipeline to avoid blocking the main CI feedback loop.
   • DIncrease the timeout for integration tests so that environment issues have more time to resolve.

   A tester is responsible for designing the automated test strategy for a team adopting CI. The team has a limited budget for test infrastructure and wants to maximize the value of automated tests in the CI pipeline. Which approach should the tester recommend?

   • AUse only unit tests in CI, as they are the fastest and cheapest to run.
   • BAutomate all tests, regardless of risk, to achieve maximum coverage.
   • CPrioritize automated tests that cover the highest-risk areas of the application and run them in the CI pipeline.
   • DRun automated tests only on the main branch to save infrastructure costs.

   A team uses a CI tool that only supports running unit tests. They want to add integration tests that require a database and a message queue. Which approach would be most appropriate to extend their CI pipeline?

   • ARun the integration tests manually on a dedicated test server after each build.
   • BSkip integration tests in CI and rely on the staging environment for integration verification.
   • CUse a separate CI tool that supports integration testing and configure it to run after the unit tests pass.
   • DExtend the existing CI pipeline by adding a stage that provisions the required services and runs the integration tests.
