#415 test and expect

Most JavaScript projects use testing frameworks like Jest or Mocha that provide functions such as test and expect.

Your task is to implement a very minimal testing utility that mimics this behavior:

Requirements

• Implement a global test(name, fn) function that:

  • Runs the function fn.
  • Logs ✅ if the test passes.
  • Logs ❌ if the test fails.

• Implement a global expect(received) function that returns an object with:

  • toBe(expected) → asserts strict equality.
  • toEqual(expected) → asserts deep equality (recursive object/array check).

Example

test('addition works', () => {
  expect(1 + 2).toBe(3);
});

test('array equality', () => {
  expect([1, 2, 3]).toEqual([1, 2, 3]);
});

Output:

✅ addition works
✅ array equality

If a test fails, it should show ❌ with the test name.

Constraints

• Do not use external libraries.
• Focus only on toBe and toEqual.
