Lesson06-test-deploy.js：TypeError: Test argument "title" should be a string. Received type "undefined"

[Minomeis]

I'm trying to run

yarn hardhat test

here is my code

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

describe("SimpleStorage", function () {

    let simpleStorageFactory, simpleStorage

    beforeEach(async function () {
        simpleStorageFactory = await ethers.getContracttFactory(
            "SinmpleStorage"
        )
        simpleStorage = await simpleStorageFactory.deploy()
    })
    it("Shoule start with a favorite number of 0", async function () {
        const currentValue = await simpleStorage.retrieve()
        const expectedValue = "0"
        // expect
        assert.equal(currentValue.toString(), expectedValue)
    })
    // it()
})

And this is the error

yarn run v1.22.19
$ /home/minomeis/hh-fcc/hardhat-simple-storage-fcc/node_modules/.bin/hardhat test

turns out i have some format problems I try to change this part

    beforeEach(async function () {
        simpleStorageFactory = await ethers.getContracttFactory(
            "SinmpleStorage"
        )
        simpleStorage = await simpleStorageFactory.deploy()
    })

to this

    beforeEach(async function () {
        simpleStorageFactory = await ethers.getContractFactory("SimpleStorage")
        simpleStorage = await simpleStorageFactory.deploy()
    })

the problem solved
