Component Testing

What is Component Testing?

Component testing sits between unit and end-to-end testing: it mounts a single UI component—a button, a form, a date picker—in isolation and verifies its rendering, props, states, and interactions without spinning up the whole application. This gives fast, focused feedback on reusable building blocks and catches regressions close to the source. It complements end-to-end tests, which confirm those components work together in real user journeys. A healthy suite blends both layers for speed and confidence.
