ReferenceError: blockToken is not defined

[kihiuFrank]

Hello guys.
I'm trying to create my own ERC20 token for practice but I'm getting an issue with my tests.

test.js

const { assert, expect } = require("chai")
const { network, ethers, deployments } = require("hardhat")
const { developmentChains } = require("../helper-hardhat-config")

!developmentChains.includes(network.name)
    ? describe.skip
    : describe("Unit tests for Block Token", () => {
          beforeEach("runs before each test", async () => {
              let accounts, deployer, blockToken
              accounts = await ethers.getSigners()
              accounts[0] = deployer
              await deployments.fixture(["blockToken"])

              blockToken = await ethers.getContract("BlockToken")
          })

          it("deploys succefully", async () => {
              assert(blockToken.address)    // error on this line
          })
      })

BlockToken.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract BlockToken is ERC20 {
    constructor(uint256 initialSupply) ERC20("Block", "BLK") {
        _mint(msg.sender, initialSupply);
    }
}

Even when I hover my cursor on blockToken, it doesn't highlight as it should.
What could be the issue?

@kihiuFrank This blockToken variable is not defined;

beforeEach("runs before each test", async () => {
    let accounts, deployer, blockToken
    accounts = await ethers.getSigners()
    accounts[0] = deployer
    await deployments.fixture(["blockToken"])

    blockToken = await ethers.getContract("BlockToken")
})

update this to this;

let blockToken;
beforeEach("runs before each test", async () => {
    let accounts, deployer, blockToken
    accounts = await ethers.getSigners()
    accounts[0] = deployer
    await deployments.fixture(["blockToken"])

    blockToken = await ethers.getContract("BlockToken")
})

Thanks @alymurtazamemon
I should declare the variables above beforeEach
