Testing and CI/CD: From Code to Production Faster Speed matters, but quality matters more. With CI/CD tools, teams automate builds, tests, and deployments to catch issues early and reduce risky surprises in production. This approach helps you move from code to users faster while keeping behavior stable and predictable. Core ideas in a modern pipeline: Build the project and install dependencies so every run starts from a clean slate. Do quick checks first: linting, type checks, and security hints. Run unit tests in parallel to get fast feedback on code changes. Execute longer tests in gates: integration tests, and, if needed, end-to-end tests in a staging-like environment. Apply security and quality gates: static analysis, vulnerability checks, and license reviews. Package artifacts and publish them, then deploy to a staging area for final sanity checks. Practical setup tips help teams start strong: ...

Testing in Production Safety and Strategies Testing in production is not reckless experimentation. It is a disciplined approach that uses controlled exposure to learn fast while protecting users. With guardrails, you can validate behavior under real load and data, not just in a lab. Why test in production? Production data reveals edge cases staging can miss. Real users, live traffic, and external services can behave differently. Safe prod testing relies on observability, fast rollback, and small blast radii. ...
