Mastering Unit Testing in Next JS & TypeScript | Portfolio App #3

Unit testing is a crucial aspect of software development, especially in modern JavaScript frameworks like Next.js and TypeScript. In this article, we will explore how to master unit testing in Next JS & TypeScript through the implementation of a portfolio app.

What is Unit Testing?

Unit testing is the process of testing individual units or components of a software application in isolation to ensure they work as expected. This helps identify and fix bugs early in the development process, leading to more robust and reliable code.

Unit Testing in Next JS & TypeScript

Next.js is a popular React framework for building server-side rendered and statically generated web applications. TypeScript, on the other hand, is a strongly-typed superset of JavaScript that adds static type checking to the language. Together, they provide a powerful and scalable platform for building modern web applications.

Setting up the Portfolio App

We will start by creating a simple portfolio app using Next.js and TypeScript. This app will showcase a list of projects with their details and allow users to filter and sort the projects based on various criteria.

Writing Unit Tests

Once the portfolio app is set up, we will write unit tests for its components, such as the project list, filters, and sorting logic. We will use testing libraries like Jest and React Testing Library to write and run our unit tests.

Running the Unit Tests

We will then run our unit tests and ensure that they pass successfully. We will also explore techniques for mocking dependencies and handling asynchronous code in our tests.

Conclusion

By mastering unit testing in Next JS & TypeScript, we can ensure that our portfolio app is high quality and reliable. This will not only benefit our app’s users but also streamline our development process and improve our overall productivity.
