Testing, Accessibility and Deployment
Explore testing strategies to verify React component behavior, understand accessibility techniques using semantic HTML and ARIA attributes, and learn deployment processes with platforms like Vercel and Netlify. This lesson helps you prepare React applications for stable, inclusive, and efficient production release.
We'll cover the following...

At this stage, we focus on testing, accessibility, and deployment. Testing ensures that our application behaves correctly as it evolves. Without testing, small changes can introduce hidden bugs that are difficult to detect. The cause is continuous code changes. The effect is the need for automated verification. Testing gives us confidence that components work as expected and allows us to refactor safely. ...
