S42-Core Test

TEST

Overview

The TEST module in s42-core provides utilities for testing your application, including tools for mocking and assertions. It is designed to simplify the testing process by providing a robust and easy-to-use interface for creating and running tests.

We recommend creating a directory called test within your project. Inside this directory, create an index.ts file. This will serve as the entry point for your tests and help organize your testing files and scripts.

Usage

While detailed examples are not included here, you can utilize the TEST module to efficiently test domain events and other parts of your application. Refer to specific documentation and examples for more comprehensive guidance on using the TEST module.

For more details and advanced usage, please refer to the additional documentation provided in the individual test files.

Testing events Domain

import { Test, EventsDomain, RedisClient } from 's42-core'


const redisInstance = RedisClient.getInstance(process.env.REDIS_URI)
const eventsDomain = EventsDomain.getInstance(redisInstance, 'testing-algo')


async function doEmitEventCreateUsers() {
  try {
    Test.Init('init doEmitEventCreateUsers')


    eventsDomain.emitEvent('users.created', {
      firstName: 'pepe',
      lastName: 'luis',
      email: 'cesarcasas@bsdsolutions.com.ar',
      lang: 'es',
      template: 'send-coupon',
    })


    Test.Ok('Test doEmitEventCreateUsers passed')
  } catch (error) {
    Test.Error('Test doInvalidTokenRequest failed:', error as Error)
  }
}
async function runTests() {
  await doEmitEventCreateUsers()
  Test.Finish()
}


console.info('Esperando instancias en listener')
const intervalId = setInterval(() => {
  const events = Object.keys(eventsDomain.getAllRegisteredEvents())
  if (events.length > 0) {
    clearInterval(intervalId)
    runTests()
  }
}, 500)
