Adding the test

For the MERN Social application, we will write a test to check whether the delete button on a post is only visible when the signed-in user is also the creator of the post. This means that the delete button will only be a part of the rendered Post view if the _id of the authenticated user is the same as the postedby value of the post data being rendered.

In order to implement this test case, we will add code that takes care of the following:

• Defines dummy data for a post and an auth object containing authenticated user details
• Mocks the methods in auth-helper.js
• Defines the test, and, within the test definition, does the following:
  • Declares the post and auth variables
  • Sets the return value of the mocked isAuthenticated method ...
