What did the CICD process look like, and how many stands were there?

The CI/CD process typically includes several stages: build, testing, deployment.

The number of environments depends on the project, but common ones include:

• Dev (development) — for integration and initial testing.
• QA (quality assurance) — for functional and integration testing.
• Staging — a pre-production environment for final checks.
• Production — the live environment.

Example process:

1. Developer pushes code to the repository.
2. Automated build and unit tests are triggered.
3. Upon success — deployment to Dev.
4. After manual or automated testing — deployment to QA.
5. After approval — deployment to Staging.
6. After final testing — release to Production.

The entire process is automated using CI/CD systems (Jenkins, GitLab CI, GitHub Actions, etc.).
