Lesson 06 - Hardhat Tests - Mocha (9:35)

describe("SimpleStorage", function () {
    let simpleStorageFactory, simpleStorage; // so that we can  access them in our its as well
    beforeEach(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";
        
        //currentValue = currentValue.toString();
        assert.equal(currentValue.toString(), expectedValue);
    });
});

I keep running into the following error when running this test
TypeError: Cannot read properties of undefined (reading 'equal')

I've read online that the error occurs "when a property is read or a function is called on an undefined variable" but that does not seem to be the case over here. console.log(currentValue.toString() returns 0 and so does the value stored in expectedValue.

The issue seems to be with the assert.equal statement because when I try assert.equal("0", "0") I get the same error message. Any ideas what may be the issue?

Issue was with my require statement. I had require("mocha") instead of require("chai")
