Solved, i create a BEP20 smart contract called DFY and uncomment the const artifactDFYToken = "DFY"; line, now i am trying to solve this errors :

  1) Deploy DFY Factory
       unit test DFY
         RRRRR => Case 1 :To test Time origin creator put on auction , check bidder bit use BNB to bid and finish with no royalty fee : :
     Error: VM Exception while processing transaction: reverted with reason string 'ERC20: transfer amount exceeds balance'

      at EthersProviderWrapper.send (node_modules\@nomiclabs\hardhat-ethers\src\internal\ethers-provider-wrapper.ts:13:20)

so i am trying to print in console what is the actual balance of the token, i am not sure but the problem can be there

Solved too, i forget premint in the BEP smart contract, now solving :

 1) Deploy DFY Factory
       unit test DFY
         RRRRR => Case 1 :To test Time origin creator put on auction , check bidder bit use BNB to bid and finish with no royalty fee : :

Solved, the error "startTime" is because in your AcutionNFT.test.js, you need to re-defining the next lines :

// success
let _startTime = Math.floor(Date.now() / 1000) + 172800; // 2d
let _endTime = _startTime + 604800; // 7d

here are what do you have in the code :

let _startTime = Math.floor(Date.now() / 1000) + 260; // 2d
let _endTime = _startTime + 70; // 7d
