草帽测试不起作用

Question

我试着在安全帽上运行一个简单的测试，但由于某些原因，它不起作用，它总是返回：

0 passing (1ms)

这是一个考验：

const { ethers } = require("hardhat")
const { expect, assert } = require("chai")

describe("SimpleStorage", async function () {
  let simpleStorageFactory, simpleStorage
  beforEach(async function () {
    simpleStorageFactory = await ethers.getContractFactory("SimpleStorage")
    simpleStorage = await simpleStorageFactory.deploy()
  })

  it("Should start with a favorite number of 0", async function () {
    const currentValue = await simpleStorage.retrieve()
    const expectedValue = "0"

    assert.equal(currentValue.toString(), expectedValue)
  })
})

当我跑步时：

yarn hardhat test

它返回0。好像测试文件是空的。

0 passing (1ms)

这是hardhat.config.js：

require("@nomicfoundation/hardhat-toolbox")
require("dotenv").config()
require("@nomiclabs/hardhat-etherscan")
require("./tasks/block_number")
require("@nomicfoundation/hardhat-chai-matchers")
require("@nomiclabs/hardhat-ethers")
require("@nomiclabs/hardhat-waffle")

const RINKEBY_RPC_URL = process.env.RINKEBY_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY
const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  defaultNetwork: "hardhat",
  networks: {
    rinkeby: {
      url: RINKEBY_RPC_URL,
      accounts: [PRIVATE_KEY],
      chainId: 4,
    },
    localhost: {
      url: "http://127.0.0.1:8545",

      chainId: 31337,
    },
  },
  solidity: "0.8.8",
  etherscan: {
    apiKey: ETHERSCAN_API_KEY,
  },
}

package.json：

所有的软件包似乎都安装在https://hardhat.org/hardhat-runner/docs/other-guides/waffle-testing中。

有什么问题吗？

Answer 1

您的beforEach(异步函数() )在前面的末尾缺少一个"e“

应该是beforeEach(异步函数() )

Answer 2

我认为问题在于，在顶级描述块中包含了async。删除它应该允许您的测试被执行。将第4行替换为这样可以解决您的问题：

describe("SimpleStorage", function () {
