Micro Router Test Server- A tiny test server for microrouter and Zeit's micro

Features

• Async. Designed for usage with async and await
• Simple. Test routes on a local live server.
• Tiny. < 60 lines of code.
• Independent. No reliance on specific testing frameworks.

Pre-requisites

Node 7+

Usage

Install as dev dependency

yarn install microrouter-test-server -D

Write a test (with Jest)

// routes.test.js
const { get, post, put } = require('microrouter');
const { json, send } = require('micro');
const { createServer } = require('microrouter-test-server');

const routes = [
  get('/route1', () => 'route1'),
  post('/route2', req => json(req)),
  put('/route3', (req, res) => send(res, 400, 'route3')),
];

let server;

beforeAll(async () => {
  server = await createServer(routes);
});

afterAll(async () => {
  await server.close();
});

test('GET of route1 should return expected value', async () => {
  const result = await server.get('/route1');
  expect(result).toEqual('route1');
});

test('POST to route2 should return the payload', async () => {
  const payload = { abc: 123 };
  const result = await server.post('/route2', {
    json: true,
    body: payload,
  });
  expect(result).toEqual(payload);
});

test('PUT to route3 should reject with non-2xx status', async () => {
  await expect(server.put('/route3')).rejects.toHaveProperty('statusCode', 400);
});

API

async createServer(routes = Array<microrouter-route>)

• routes - an array of routes returned by the route methods (get, post, put, del, patch, head and options) of microrouter
• returns Promise<Object> with methods:
  • get(uri: String, options: RequestOptions)
  • post(uri: String, options: RequestOptions)
  • put(uri: String, options: RequestOptions)
  • del(uri: String, options: RequestOptions)
  • patch(uri: String, options: RequestOptions)
  • head(uri: String, options: RequestOptions)
    • uri is the relative path to the route
    • options is the configuration object for request/request-promise
    • methods return a promise ala request-promise

async close()

• Closes the active connection to the test server.

Examples

POST a payload

const result = await server.post('/route2', {
  json: true,
  body: { my: 'payload' },
});

Handle non-2xx responses

microrouter-test-server uses request-promise to handle requests. By default, this library rejects on any status other than a 2xx. Here's a few ways to handle it:

.catch(StatusCodeError)

server.post('/route')
  .then(body => {
    // 2xx status 
  })
  .catch(err => {
    console.log(err.statusCode);
  })

Get the full response object

const response = await server.post('/route', {
  simple: false,
  resolveWithFullResponse: true,
});

if (response.statusCode == 200) {
  doSomething(response);
} else {
  handleFailure();
}
