Write, Test and Debug Vue 3 Components in the Browser Using Cypress

Approaching testing at a component level has definitely its benefits. Seeing your component rendered in isolation, and making sure it behaves correctly with different properties is definitely faster that trying to interact with an app at end-to-end level. On the other hand, seeing your app render in a browser in an end-to-end test is a significant advantage.

With Cypress’ component testing you can now take the best of both worlds. Render component and interact with it in a real browser. You can pass different properties, spy on its function calls, click and type into them or even intercept its network calls. All this with a minimal setup and vast options.
