【问题描述】：

我正在 youtube 上关注本教程 \"https://www.youtube.com/watch?v=7QsqElEaWBQ\"

我已经仔细检查以确保我的代码匹配，但我被困在我正在测试项目的 41:00 分钟标记处。它始终显示“0 通过”。我在教程视频中没有看到失败消息。这让我相信他们甚至没有得到测试。我已经安装了开始时所需的所有依赖项，检查以确保我的文件名匹配但仍然没有运气。此测试使用的是 hardhat-waffle。

这是我的 \"Testing.js\" 文件代码 =>

    const { expect } = require(\"chai\");
const { ethers } = require(\"ethers\");
const {
  isCallTrace,
} = require(\"hardhat/internal/hardhat-network/stack-traces/message-trace\");

describe(\"Staking\", function () {
  beforeEach(async function () {
    [signer1, signers2] = await ethers.getSigners();

    Staking = await ethers.getContractFactory(\"Staking\", signer1);

    staking = await Staking.deploy({
      value: ethers.utils.parseEther(\"10\"),
    });
  });

  describe(\"deploy\", function () {
    it(\"should set owner\", async function () {
      expect(await staking.owner()).to.equal(signer1.address);
    });
    it(\"sets up tiers and lockPeriods\", async function () {
      expect(await staking.lockPeriods(0)).to.equal(30);
      expect(await staking.lockPeriods(1)).to.equal(90);
      expect(await staking.lockPeriods(2)).to.equal(180);

      expect(await staking.tiers(3)).to.equal(700);
      expect(await staking.tiers(3)).to.equal(1000);
      expect(await staking.tiers(3)).to.equal(1200);
    });
  });

  describe(\"stakeEther\", function () {
    it(\"transfers ether\", async function () {
      const provider = waffle.provider;
      let contractBalance;
      let signerBalance;
      const transferAmount = ethers.utils.parseEther(\"2.0\");

      contractBalance = await provider.getBalance(staking.address);
      signerBalance = await signer1.getBalance();

      const data = { value: transferAmount };
      const transaction = await staking.connect(signer1).stakeEther(30, data);
      const receipt = await transaction.wait();
      const gasUsed = receipt.gasUsed.mul(receipt.effectiveGasPrice);

      //test the change in signer1\'s ether balance
      expect(await signer1.getBalance()).to.equal(
        signerBalance.sub(transferAmount).sub(gasUsed)
      );

      // test the change in contract\'s ether balance
      expect(await provider.getBalance(staking.address)).to.equal(
        contractBalance.add(transferAmount)
      );
    });
  });
});

如果您知道如何解决我的问题，请告诉我。那对我会有很大的帮助！

【解决方案1】：

我认为您正在从 mocha 导入 beforeEach
