express-test-server

A minimal but customizable Express server for testing

Typescript based preconfigured Express application intended for quick testing requests and responses, it can can be customized to listen for HTTP and HTTPS traffic and alter the default body parser behavior.

The following Content-Type headers will be parsed and exposed via req.body:

• JSON (application/json)
• Text (text/plain)
• URL-Encoded (application/x-www-form-urlencoded)
• Buffer (application/octet-stream)

Installation

npm install --save-dev @b4dnewz/express-test-server

Getting started

import createServer from "@b4dnewz/express-test-server"

const server = await createServer({
  // server options
});

// Express route handler
server.get('/foo', (req, res) => {
  res.send('bar');
});

// Express alternative route handlers
server.get('/bar', () => 'foo');
server.get('/baz', 'foo');

Perfect for testing

import createServer from "@b4dnewz/express-test-server"

let server;

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

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

it("respond to get requests", async () => {
  sever.get("/foo", "bar")
  const {body} = await got(`${server.url}/foo`)
  expect(body).toEqual("bar")
})
