A simple TDD case for a `/cats` endpoint

testCatsEndpoint.js

import chai, { expect } from "chai";
import chaiHttp from "chai-http";
import server from "../server";

chai.use(chaiHttp);

const ENDPOINT = "/api/v1/cats";
let request = null;

describe("/api/v1/cats", () => {
  before(() => {
    request = chai.request(server).keepOpen();
  });

  after(() => request.close());

  describe("GET /", () => {
    it("should respond with an array of cats", done => {
      request.get(ENDPOINT).then(res => {
        expect(res.body).to.be.an("array").that.is.not.empty;
        done();
      });
    });
  });
});

Superb one, @codeshifu.

Thanks for providing clarity with the comment, too. 🎉
