Quality Assurance Projects - Sudoku Solver Unit Tests

I have written the sudoku-solver.js and api.js code and all the tests are passing.

I am now trying to write the first Unit Test and have written:

const chai = require('chai');
const assert = chai.assert;

const Solver = require('../controllers/sudoku-solver.js');
let solver = new Solver();

suite('Unit Tests', () => {
  test('Logic handles a valid puzzle string of 81 characters', function (done) {
    assert.equal(solver.validate('..9..'), { result: true });


This doesn’t work and I get the following:

npm run start

> sudoku-solver@2.0.0 start
> nodemon server.js

[nodemon] 2.0.20
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node server.js`
Listening on port 3000
Running Tests...

  Unit Tests
    1) Logic handles a valid puzzle string of 81 characters

  0 passing (14ms)
  1 failing

  1) Unit Tests
       Logic handles a valid puzzle string of 81 characters:

      AssertionError: expected { result: true } to equal { result: true }
      + expected - actual

      at Context.<anonymous> (tests/1_unit-tests.js:9:12)
      at processImmediate (node:internal/timers:471:21)

signal: terminated

Looks to me like the expected and actual are the same

I tried using assert.deepEqual and it worked :slightly_smiling_face:
