Migration to Playwright

[Martynienas]

Added long lived branch named Playwright:

Currently it's just a proof concept and most of the functionality is broken:

• With some hacks managed to make Visual Regression example suite successfully execute on Chrome browser.

What is done:

• Uninstalled all puppeteer dependencies

  • jest-puppeteer
  • puppeteer

• Added Playwright dependencies:

  • playwright
  • jest-playwright-preset
  • eslint-plugin-jest-playwright

Hacks:

• content of test-environment/setup.js is commented out - jest-environment-puppeteer is missing
• jest.config.js global Setup and Teardown - also testEnvironment and setupFilesAfterEnv are commented out - relays on removed dependencies
• Toggled of screenshots by default (fails if enabled)

Steps taken into right direction:

• Added jest-playwright.config.js - configuration file for Playwright - currently contains the following settings:
  • Tests executed on Chrome,Firefox and Webkit
  • Executed in Headless mode
  • devtools: false,
• Changed page.waitFor -> page.waitForSelector
• page.setViewport ->page.setViewportSize

Following steps:

• Fix global Setup
• Fix global TearDown
• Fix testEnvironment setup
• Fix setupFilesAfterEnv setup
• Fix remaining tests
• Fix logging
• Fix Screenshots
• Fix Visual Regression tests to be able to handle screenshots based on browser it is executing on
