Can I test the app directly, instead of an individual route?

[nikoschon]

describe('Jest setup', () => {
  test('Get all accounts', async () => {
    const request = createRequest({
      method: 'GET',
      url: '/api/accounts',
    });
    const response = createResponse();

    await app(request, response);

    console.log(response._getData());
  });
});

The route is hit after the end of test.

This depends if you app() function returns a promise or not

[nikoschon]

forgot to mention this. This is an express app instance const app = express();

Then it won't work.

You can take a look into supertest - it is more suitable to test the whole app.

Looks like the same issue with testing a express.Router. If a route is async, then the router will not wait for the promise to resolve and return early, but not return a promise itself so there's nothing for the test to await on.

supertest works great!
