Chapter 6: Testing Front-End Applications
Testing software is an essential part of software development. We can prevent errors and ensure that new features don't introduce bugs by implementing well-designed tests.
In this chapter, you'll understand software testing by learning how to design integration and end-to-end tests and apply them in the development process. After that, you'll learn how to write tests using Jest, a JavaScript test framework focused on simplicity that works well with React. You'll also learn how to test interfaces by simulating user actions with Puppeteer and Headless Chrome.
In this chapter, we'll cover the following main topics:
- Understanding software testing
- Writing tests with Jest
- Testing interfaces with Puppeteer
By the end of this chapter, you'll have learned how to design integration and end-to-end tests and how to apply them to improve software quality. You'll have learned how to write tests...
