React Testing Library (RTL) provides lightweight utilities built on top of react-dom and react-dom/test-utils, designed to promote testing through user interactions rather than component internals. Instead of working with component instances, RTL encourages querying and asserting against actual DOM nodes, just like real users would. This approach improves test reliability and pushes developers toward writing more... - Source: dev.to / 2 months ago

Testing ensures code reliability and maintainability. Jest, Vitest and React Testing Library are standard tools for unit and integration testing. Unit tests verify individual components, while integration tests ensure features work together. For example, testing a TodoList component might involve:. - Source: dev.to / 3 months ago

Additionally, I wrote Jest and Enzyme unit tests to demonstrate how to go about unit testing the components, as test driven development (TDD) is another methodology my organization subscribes to. Jest is a unit testing framework that actually shipped with React if you use the Create React App CLI to make a new React project. And at the time, Enzyme was created by Airbnb and added additional functionality to Jest... - Source: dev.to / 6 months ago

After converting your components, take some time to test your application. Make sure everything is working as expected. React’s development server automatically reloads your application whenever you save changes, which makes testing a lot easier. Tools like Jest and React Testing Library are also available to help you write tests for your components. - Source: dev.to / 6 months ago

A special kind of validation is enforcing that record fields are not null. (Un)fortunately, records do not have any special behavior regarding nullability. You can use tools like NullAway or Error Prone to prevent null in your code in general, or you can add checks to your records:. - Source: dev.to / almost 3 years ago

I am all in favour to more third side libraries adding functionalities, like Lombok, Manifold and error prone. As well as smaller projects like this shameless plug and what appears in this list. Source: almost 3 years ago

While at it you could also point them to static code analyzers such as error_prone, spotbugs and pmd (use all 3 at once - they complement each other in detecting different issues). Source: almost 4 years ago

Linters can check for this sort of thing, for example Error Prone[0] has a lint[1] for this. Totally agree this is better to be in the language proper so we don't need this extra tooling.
