Utils

const {
  start, stop,
  url,
  stdMock, stdRestore 
  $get, $post, $put, $del
= require('mono-test-utils')

Contents

Start a Mono project from dir directory with NODE_ENV=test:

const context = await start(dir, options = {})
// context = { log, conf, app, server, stdout, stderr }

Default options:

{
  env: 'test',
  monoPath: 'mono-core'
}

Stop Mono server:

await stop(context.server)

Get the url of your mono server:

url()
// http://localhost:8000 (port updates depending of the mono conf)
url('/test')
// http://localhost:8000/test

Mock stdout and stderr

This is useful for capturing logs (based on std-mocks).

Example:

// Start mocking stdout and stderr
stdMock()
 
console.log('test log')
console.error('test error')
 
const { stdout, stderr } = stdRestore()
// stdout = ['test log\n']
// stderr = ['test error\n']
  • stdMock() will call stdMocks.use(options)
  • stdRestore() will call stdMocks.restore() and return stdMocks.flush().

Make HTTP requests to the API:

await $get(path, options = {})
await $post(path, options = {})
await $put(path, options = {})
await $del(path, options = {}) // alias: `$delete`

Also available: $head, $options and $patch

INFO: The options are the same as request.

Every of the following methods return an object with these properties:

{
  statusCode, // HTTP status code
  headers, // Headers sent back
  body, // Body of the response
  stdout, // Logs written on stdout during the request
  stderr // Logs written on stderr during the request
}

Example

Example of test/index.js with ava:

const test = require('ava')
const { join } = require('path')
 
const { start, stop, $get, $post } = require('mono-test-utils')
 
let context
 
// Start server
test.before('Start Mono app', async (t) => {
  context = await start(join(__dirname, 'fixtures/example/'))
})
 
// Test API Endpoints
test('Call GET - /example', async (t) => {
  const { stdout, stderr, statusCode, body } = await $get('/example')
  t.true(stdout[0].includes('GET /example'))
  t.is(stderr.length, 0)
  t.is(statusCode, 200)
  // Imagine that GET - /example returns { hello: 'world' }
  t.deepEqual(body.body, { hello: 'world' })
})
 
test('Call POST - /example', async (t) => {
  const { statusCode, body } = await $post('/example', {
    body: { foo: 'bar' }
  })
  t.is(statusCode, 200)
})
 
// Close server
test.after('Close Mono server', async (t) => {
  await close(context.server)
})
