小號OLV_和D小號○大號在和DSOLVEDPatrickCollins Solidity Course 2022 - 第 7 課：11:20:38 -> TypeError：ethers.getContract 不是函式

AssertionError: Expected transaction to be reverted with You need to spend more ETH!, but other exception was thrown: Error: Transaction reverted: function returned an unexpected amount of data

在影片的 11:20:38 左右執行 fundMe() 測試時出現此錯誤

describe("FundMe", async function () {
 let fundMe;
 let deployer;
 let MockV3Aggregator;
 beforeEach(async function () {
   deployer = (await getNamedAccounts()).deployer;
   await deployments.fixture(["all"]);
   fundMe = await ethers.getContract("FundMe", deployer);
   MockV3Aggregator = await ethers.getContract("MockV3Aggregator", deployer);
 });

 describe("constructor", async function () {
   it("sets the aggregator addresses correctly", async function () {
     const response = await fundMe.priceFeed();
     assert.equal(response, MockV3Aggregator.address);
   });
 });
 describe("fund", async function () {
   it("Fails if you don't send enough ETH", async function () {
     await expect(fundMe.fund()).to.be.revertedWith(
       "You need to spend more ETH!"
     );
   });
 });
});

經過一些研究，似乎可以通過從安全帽文件下載@nomicslabs/hardhat-waffle 來解決這個問題

$$ https://hardhat.org/plugins/nomiclabs-hardhat-waffle $$ 但是在執行安裝後，我現在在執行上述測試時遇到以下錯誤

 1) FundMe
      "before each" hook for "sets the aggregator addresses correctly":
    TypeError: ethers.getContract is not a function

關於這裡可能是什麼問題的任何想法？謝謝你！

$$ SOLVED $$ 我試圖修改該行，使其顯示為： await expect(fundMe.fund()).to.be.reverted

正如您在下面看到的那樣，這兩個測試似乎都通過了

所以這絕對是行，但我仍然不明白為什麼添加字元串會導致錯誤，也許我缺少參數或導入。

yarn add hardhat--dev @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers ethers

再次執行並解決了問題。

現在測試 1 通過，但測試在到達時返回以下錯誤

await expect(fundMe.fund()).to.be.revertedWith("You need to spend more ETH!");

錯誤：

 1) FundMe
      fund
        Fails if you don't send enough ETH:
    AssertionError: Expected transaction to be reverted with You need to spend more ETH!, but other exception was thrown: Error: Transaction reverted: function returned an unexpected amount of data
