Problem description:

I am following the jest setup video of the course Testing React applications, v2 at frontend masters'. I have written the test script in mypackage.jsonand trying to runnpm test` command. But jest is showing that there are two configurations. I don't understand that. I tried to find solutions on google search but couldn't found.

Here is the output. Please help so I can continue the setup.
