When is the automatic pipeline launch initiated during development or deployment?

Automatic pipeline execution is usually triggered by specific events during development or deployment processes. Most commonly, this occurs when:

• Committing to a version control system (e.g., Git) — when a developer pushes changes to the repository, the CI/CD system automatically starts the build and tests.
• Creating or updating a Pull Request (Merge Request) — to verify changes before merging.
• Scheduled runs — for example, on a timetable for regression testing.
• Manual trigger via the CI/CD interface — when a specific scenario needs to be tested.

Thus, automatic pipeline execution is closely related to events in the version control system and the process of code integration and delivery.
