How do you implement changes in the 'develop' and 'test' environments?

Implementation of changes in the 'develop' and 'test' environments usually occurs through automated CI/CD processes:

• Developer pushes changes to the develop branch.
• CI system (e.g., Jenkins, GitLab CI, GitHub Actions) triggers build and tests.
• After successful testing, artifacts are automatically deployed to the develop environment for integration testing.
• Similarly, for the test environment, there may be a separate branch or tag, which when updated, triggers deployment to the test environment.

This allows for quick and reliable deployment of changes, minimizing manual errors. Infrastructure tools (Ansible, Terraform, Helm) are often used for configuration management and deployment.

Example of a simple pipeline in GitLab CI:

stages:
  - build
  - test
  - deploy

build_job:
  stage: build
  script:
    - ./build.sh

test_job:
  stage: test
  script:
    - ./run_tests.sh

deploy_develop:
  stage: deploy
  script:
    - ./deploy.sh develop
  only:
    - develop

deploy_test:
  stage: deploy
  script:
    - ./deploy.sh test
  only:
    - test
