Chapter 2: Automated Testing and Test runners
In Chapter 1, Getting started with Puppeteer, we covered the first fundamental pillar of this book: browser automation and headless browsers. In this chapter, we are going to cover the second pillar: UI testing. We learned that Puppeteer is not just about testing, but that doesn't mean that it's not an excellent tool for the job.
In this chapter, we are going to learn the fundamentals of Testing Automation. We are going to see the differences between UI Testing and End-to-End testing. If you have tried to write tests in Node.js before, you might have come across some weird names: Mocha, Jest, Jasmine, AVA, or Chai. That feels quite overwhelming if you are not used to these tools. We are going to see which are the right tools for us.
We will cover the following topics in this chapter:
- Introduction to Automated Testing
- Test runner main features
- Available Test runners
- Creating our first test project
- Organizing our code
Once we understand these foundational concepts and we learn how test runners work, we will be able to dive deep into the Puppeteer API.
