Introducing React testing helpers

In this section, we are going to learn about the fundamentals of RTL. But first, let’s try to understand what testing means when it comes to programming so that we can learn about the core concepts and methodology.

What is testing in software development?

Reviewing a software program or system to verify it satisfies its functional and non-functional criteria and certifying its overall quality, performance, and dependability is known as testing in software development. It comprises running the program under controlled settings to find mistakes, flaws, or possible problems before the product is delivered to end customers.
