Continuous Validation

Integrating Code Continuously

Continuous verification is a system where freshly created code is automatically blended into the core repository. Unlike the outdated and sluggish method of individually incorporating every change at a cycle's completion, continuous verification offers developers an easier platform to scrutinize their work repeatedly if required.

It's clear that many development squads are adopting automated validation, due to its ability to swiftly and seamlessly attest to the accuracy of code. Automation itself pinpoints and highlights errors or defects in need of correction. Besides its speed and ease, automation safeguards the primary database from potential new glitches arising from the application of newly crafted code. The new code is thus unable to disrupt the functionality of the existing code. However, the probable deterrent for many is that successful automation construction requires substantial time investment.

Validation in Perpetuity

Following automation comes continuous operations validation, including concurrent software examination methods that test an item’s internal structure and design. Essentially, both black and white box testing addresses those sections of code where glitches or issues have occurred to enable the development team to rectify them speedily and painlessly.

Continuous verification tackles and mitigates significant risks and provides development teams with a stable construction, facilitating efficient testing. Consequently, continuous integration's aim is the smooth combination of both old and new codes. When founded on solid grounds, integration decreases costs and enables testing teams to respond promptly to bugs and issues within the code.

Sustained Delivery

Continuous delivery is the final expanded link that begins where continuous integration concludes. Its primary role is the automatic and effortless code or application transfer to specific infrastructures such as development, production, and testing environments. Notably, many developer teams operate in several of these environments, and continuous delivery allows swift code alterations.

Continuous delivery ensures that developers promptly observe the behaviour of code changes. Worth noting is that the quality of the code is guaranteed, as integration gets done before delivery. Therefore, the ultimate objective is to deliver high-quality applications to end-users.

Continuous delivery involves a series of processes: release, test, deploy, and build. Both continuous integration and continuous delivery necessitate continued testing and monitoring, including various automated regression and performance tests performed within a CI/CD pipeline.

Testing and Monitoring in a CI/CD setting

The optimal practice is to require developers to conduct regular checks within their environments, ensuring code application only when all parameters get met.

Continuous tests go beyond regression tests: security testing, API testing, and performance testing – all can be automated. However, testing machine learning is more complex compared to other software systems and needs data validation. More advanced CD pipelines include methods for ML model monitoring, validation, and quality evaluation. A robust automated CI/CD is essential for machine learning to reliably update production pipelines.
