Testing and CI/CD: Shipping Software with Confidence Testing and CI/CD are not just tools; they shape how teams work. They give us confidence to ship changes quickly while keeping customers safe. A well designed pipeline turns guesswork into repeatable, auditable steps. A strong test strategy follows the test pyramid: fast unit tests for logic, a middle layer of integration tests, and a smaller set of end-to-end tests that reflect real user flows. This mix helps catch bugs early without slowing delivery. ...

Testing strategies and CI CD explained Teams use testing to build confidence early. A clear strategy helps balance speed and quality across the life of a project. The goal is to catch mistakes before they reach users and to keep deployments smooth. A well planned approach also helps teams decide where to invest time and what to automate. The test pyramid Think of tests like a pyramid: many fast unit tests at the bottom, fewer integration tests in the middle, and even fewer end-to-end tests on top. Unit tests verify small pieces in isolation and run quickly. Integration tests check how modules work together. End-to-end tests simulate real user journeys and are slower and more brittle. In practice, aim for fast feedback from the bottom, with a smaller set of higher level checks that cover critical flows. ...
