1/5 · Testing Throughout the Software Development Lifecycle
A team practices DevOps with a CI/CD pipeline. Which practice best exemplifies the shift-left philosophy within this DevOps context?
ADeploying the change to production first, then running exploratory tests to see whether anything broke.
BAutomated component and API-level tests run in the CI pipeline immediately after each commit, giving developers fast feedback before the change is merged to the main branch.
CWaiting until a nightly build to run any automated tests because immediate feedback would slow down developers.
DRunning only manual system tests once per release cycle, shortly before deployment.

According to the ISTQB CTFL syllabus, what is the main purpose of holding a retrospective (e.g., an end-of-sprint retrospective) with respect to testing?
ATo identify what worked well and what could be improved in testing and other project activities, so lessons learned can be applied to future iterations.
BTo assign responsibility to specific team members for defects found in the previous iteration.
CTo formally sign off on acceptance test results before releasing the software to production.
DTo re-execute all regression tests one final time immediately before the retrospective meeting.

Which statement best distinguishes functional testing from non-functional testing as test types in the ISTQB CTFL syllabus?
AFunctional testing evaluates what the system does (its functions), while non-functional testing evaluates how well the system performs, such as its performance, usability, or reliability.
BFunctional testing can only be performed manually, while non-functional testing can only be automated.
CNon-functional testing verifies the internal code structure, while functional testing verifies external behavior only.
DFunctional testing is executed exclusively at the system test level, while non-functional testing is executed exclusively at the acceptance test level.

Which of the following is NOT typically listed in the ISTQB CTFL syllabus as a trigger for maintenance testing?
AMigration of the system to a different hardware or software platform.
BA corrective emergency change (hotfix) applied to a live production system.
CInitial development and first release of a brand-new system that has never previously been deployed to production.
DRetirement or decommissioning of a system, including testing related to data archiving and migration of retained data.
Show answer & explanation
C is correct. The syllabus lists modification (planned enhancement, corrective or emergency change, or changes of environment such as OS/DB upgrades), migration, and retirement of a system as triggers for maintenance testing. These all presuppose an existing, already-deployed system; the first release of a brand-new system is not maintenance testing.
