Level 34: Test a GET JSON Route

Add a test for one of your GET routes that returns JSON data (e.g., GET /items or your own resource route). Test that it returns an array and has the correct status code.

Show Me: GET JSON route test

it('returns seeded items array', async () => {
  const res = await request(app).get('/items');
  expect(res.status).toBe(200);
  expect(Array.isArray(res.body)).toBe(true);
  expect(res.headers['content-type']).toMatch(/json/);
});
