CI/CD

Even for patch updates, it is recommended to run the full test suite in the CI pipeline to ensure consistent application behavior after upgrading.

CI is an abbreviation for Continuous Integration, and CD is an abbreviation for Continuous Delivery/Deployment.

The concept of CI/CD can be traced back to the continuous integration practices proposed by Martin Fowler and Kent Beck in Extreme Programming (XP) in the early 2000s.

Continuous delivery means that code is always in a releasable state but going live requires manual confirmation, whereas continuous deployment means that code is automatically pushed to the production environment once tests pass.

The prerequisite for CI/CD to safely automate releases is that the preceding automated testing is sufficiently comprehensive; without reliable tests, the pipeline becomes a tool that accelerates the spread of bugs.

DevSecOps mandates the embedding of security checkpoints within CI/CD pipelines, including automated tools such as Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Software Composition Analysis (SCA).

The concept of composable building blocks is highly compatible with Platform Engineering, where platform teams pre-encapsulate infrastructure templates, CI/CD configurations, and security compliance policies for business teams to use.

The evolution of Agent evaluation platforms mirrors the consolidation of CI/CD platforms in software engineering, where teams converged on unified continuous integration platforms like Jenkins or GitHub Actions

The challenge of embedding AI agents into CI/CD pipelines lies in the fact that CI/CD is a deterministic system while AI agents are probabilistic, requiring the design of deterministic wrappers that layer a rules engine on top of AI judgment

The concept of deterministic validation gates draws on the Quality Gate idea from CI/CD pipelines.

The automated validation layer typically relies on CI/CD pipeline concepts, including steps such as static analysis, type checking, unit test execution, integration testing, and security scanning.

The underlying model of CI/CD is essentially a finite state machine, where the system is in one of a finite number of states at any given moment and transitions between states via clearly defined transition conditions.

After a code repository is flagged by a security scan, common consequences include interruption of the CI/CD pipeline, rejection of pushes by the artifact repository, failure of dependency audits, and the need to manually submit an exemption request.

REVA's throughput of one function per second is sufficient to be embedded in CI/CD pipelines, completing a first-pass filter before code is merged.

A typical CI/CD pipeline sequentially completes stages such as pulling code, packaging, building the image, pushing the image, and having the production server pull the image and start the container.

To prove that tests came first, the two test files before and after the fix remained unchanged, ensuring that the error was identified first and the fix verified afterward, rather than relaxing the checks in exchange for passing.

Exporting the generated output to GitHub means exporting it as a standard code repository, which can be integrated into CI/CD, code review, and version management processes.

Pre-merge verification in CI/CD usually means automatically running builds, tests and static checks before code is merged into the main branch to ensure changes do not break the trunk, with common implementations including GitHub Actions pull request checks and GitLab CI merge request pipelines.

Automatically completing releases through the CI/CD pipeline ensures that the release process is repeatable and traceable, but release notes usually require additional manual supplementation.
