我正在测试一个 ERC721 令牌的智能合约，它继承自 OpenZeppelin，使用 waffle 和 chai 和 NodeJS v14.18.0，但 chai 的还原断言似乎没有按预期运行。

依赖项：

  "devDependencies": {
    "@nomiclabs/hardhat-ethers": "^2.0.1",
    "@nomiclabs/hardhat-etherscan": "^2.1.0",
    "@nomiclabs/hardhat-waffle": "^2.0.1",
    "@typechain/ethers-v5": "^5.0.0",
    "@types/chai": "^4.2.14",
    "@types/mocha": "^8.2.0",
    "@types/node": "^14.14.14",
    "chai": "^4.2.0",
    "dotenv": "^8.2.0",
    "ethereum-waffle": "^3.2.1",
    "ethers": "^5.0.24",
    "hardhat": "^2.0.5",
    "hardhat-typechain": "^0.3.4",
    "ts-generator": "^0.1.1",
    "ts-node": "^9.1.1",
    "typechain": "^4.0.1",
    "typescript": "^4.1.3"
  },

示例代码：

  let genesisTokenHolders: Array<string>;

        beforeEach(async () => {
            genesisTokenHolders = new Array(230).fill('0x0000000000000000000000000000000000000000')
            genesisTokenHolders[1] = addr1.address;
            genesisTokenHolders[2] = addr2.address;
        })

        describe('airdrop genesis tokens', async () => {
            it('should fail when non-owner calls the function', async () => {
                
                let addGenesisHoldersTx = await myToken.addGenesisTokenHolderAddresses(genesisTokenHolders)
                await addGenesisHoldersTx.wait();
                    
                await expect(await myToken.connect(addr1).airdropTokensToGenesisHolders(1, 2)).to.be.revertedWith("Ownable: caller is not the owner");
            })
        
            it('should succeed when called by the owner', async () => {

                let addGenesisHoldersTx = await myToken.addGenesisTokenHolderAddresses(genesisTokenHolders)
                await addGenesisHoldersTx.wait();
 
                let airdropTx = await myToken.connect(deployer).airdropTokensToGenesisHolders(1,2);
                await airdropTx.wait();
            
                // addr1 should own tokenID 1, addr2 should own tokenId 2
                await expect(await myToken.ownerOf(1)).to.hexEqual(addr1.address)
                await expect(await myToken.ownerOf(2)).to.hexEqual(addr2.address)
                
                await expect(await myToken.ownerOf(1000)).to.be.reverted;
            })
        });

尽管使用.to.be.revertedWith()and .to.be.reverted，测试套件仍然抛出错误：

         airdrop genesis tokens
           should fail when non-owner calls the function:
     Error: VM Exception while processing transaction: revert Ownable: caller is not the owner

         airdrop genesis tokens
           should succeed when called by the owner:
     Error: VM Exception while processing transaction: revert ERC721: owner query for nonexistent token

预期结果：测试应该通过。

不要等待承诺在内部得到解决expect

更改自：

await expect(await myToken.ownerOf(1000)).to.be.reverted;

至：

await expect(myToken.ownerOf(1000)).to.be.reverted;
