[Shawon-Mandal]

I wrote the RandomIpfsNft.test.js according the git repo and got this huge error :

Basic NFT Unit Tests
Constructor
✓ Initializes the NFT Correctly.
Mint NFT
✓ Allows users to mint an NFT, and updates appropriately
✓ Show the correct balance and owner of an NFT

Random IPFS NFT Unit Tests
constructor

  1) sets starting values correctly
requestNft

  2) fails if payment isn't sent with the request

  3) reverts if payment amount is less than the mint fee

  4) emits an event and kicks off a random word request
fulfillRandomWords

  6) should revert if moddedRng > 99
