jest-environment-detox

Pitch & Anti-pitch

• Inspired by jest-environment-puppeteer implementation
• Allow a detox server to be shared between multiple test suites
• Make sure app is not reinstalled between test suites (Fixes #1331 and #1331)
• Anti-pitch: Uses detox & jest private APIs
• Anti-pitch: Somewhat opionated

   // ./jest/setup.js
      	
   import { getDetoxSession } from 'jest-environment-detox';
        
   const config = require('../package.json').detox;
      
   beforeAll(async () => {
   	await detox.init({
   		...config,
   		session: getDetoxSession(process.env.JEST_WORKER_ID),
   	}, {
   		launchApp: false,
   		reuse: true,
