Setup NodeJS playwright and run the first script
What is Playwright?
The playwright is a NodeJs-based automation framework. It is developed by Microsoft with the same team which also developed Puppeteer. (Click here to read posts on Puppeteer). It helps to automate the browser with/without headless. It provides additional functionality over Puppeteer like cross-browser support, cross-programming language support, auto wait, default reports, and much more.
Here is the youtube video where I have discussed, what is playwright? Advantages of the playwright, installation, explained example script, run the first playwright test with and without headless mode. Watch the video and subscribe to the channel.

Playwright by default provides HTML report. You need not to configure anything specific for that. If something gets failed it opens the automation report by default else need to open through file or with this command
