As the name implies, unit test is all about testing individual units of code. In ORDER to answer some questions, isolating the unit of code under test is really important. When we do this, we are not forced into CREATING related pieces such as DOM ELEMENTS for sorting. With the help of isolated unit tests, it becomes easier to IMPLEMENT everything. To simulate the requests, dependency injections are ALSO provided. The individual sort function can be tested in isolation. And not only the sort function, any function can be tested in isolation.
