Today we will learn how to get started and write snapshot test for react component.

Some people like snapshot testing because it is very easy to write, easy to update and provides a declarative way of testing react components but some people don't like snapshot testing because TDD aka test driven development is not possible as the snapshot is taken after the component is developed, so there is no way for developing the snapshot before writing the component.
Another reason is that it will not tell you about the expected output, they just ensure that the components hasn’t changed.

It is also important to understand that how snapshot testing works.
I have prepared a simple flow chart to better explain it to you. Hope you will enjoy this video.
