   A tester is working on an agile team that has just adopted continuous integration. The tester wants to ensure that the team's automated tests provide the most value in the CI pipeline. Which action should the tester take?

   • AReplace manual exploratory testing with automated tests to ensure full coverage.
   • BRun all automated tests only at the end of the sprint to avoid interrupting development.
   • CWrite as many automated tests as possible, regardless of execution time, to maximize coverage.
   • DPrioritize the automated tests so that the fastest, most critical tests run first in the CI pipeline.

   A team is considering whether to adopt continuous integration. They are concerned about the overhead of setting up and maintaining a CI pipeline. Which benefit of CI would most justify this overhead?

   • AReduced integration risk and early defect detection, leading to lower overall cost of fixing defects.
   • BElimination of the need for manual testing, saving time and resources.
   • CGuarantee that the software is always free of defects.
   • DReduction in the number of developers needed on the team.

   A team of five developers works on a web application. Each developer works on a separate feature branch and merges to the main branch only when the feature is complete, which often takes two to three weeks. The team reports that integration problems are discovered late and consume significant time to resolve. Which change to their workflow would most directly address the root cause of their integration problems?

   • AIntegrate code into the main branch at least once per day, with automated builds and tests running on each integration.
   • BSchedule a weekly integration day where all developers merge their branches and resolve conflicts together.
   • CRequire all developers to work on the same feature branch to avoid merge conflicts.
   • DIncrease the frequency of code reviews on feature branches before merging to the main branch.

   What is the primary purpose of continuous integration in agile software development?

   • ATo provide a dedicated environment for each developer to work on code changes without affecting others.
   • BTo ensure that the software is deployed to production automatically after every code change.
   • CTo replace manual testing with automated testing in all phases of the software development lifecycle.
   • DTo ensure that all code changes are integrated into a shared mainline frequently, allowing early detection of integration problems.
