Tell us about your experience setting up automatic triggers for branches in the build system

Automatic triggers for branches in build systems (such as Jenkins, GitLab CI, GitHub Actions) allow running builds, tests, or deployments when changes occur in specific repository branches. This is usually configured through configuration files or UI:

• In Jenkins, you can set up a trigger for push events on a specific branch via the "Branch Specifier" parameter in the job settings.
• In GitLab CI, the .gitlab-ci.yml file specifies the only or rules key with branches, for example:

job:
  script: make test
  only:
    - master
    - develop

• In GitHub Actions, the .github/workflows/ci.yml file specifies:

on:
  push:
    branches:
      - main
      - feature/*

Thus, when a push occurs to the specified branches, the pipeline is automatically triggered. This helps automate code verification and speeds up integration of changes.
