Browser Testing vs Javascript Testing Framework

JS tests tend to be limited, hard to implement, and slow, so many front-end developers don't want to make JS tests. In some circumstances, TDD is known as the process of back-end development because there are much many framework help back-end developers to create the testing processes, the most specifically framework that I'm using every day in Ruby language is RSpec, it has many documentations, active communities. In contrast to Javascript tests, I have recently been using Jest - a testing framework made by Facebook.

As you can see, their slogan promises a “painless” JavaScript Testing. And indeed, Facebook have an excellent reason to use this slogan. In general, JS developers are not too happy with website testing. Nevertheless, with the right strategy and the right combination of tools a nearly full coverage can be achieved and tests can be very organized, simple, and relatively fast. I will point out some testing definitions, this is not only for front-end development but also back-end, so please read carefully
