What
End-to-end testing is a technique used to test whether the flow of an application is performing as designed from start to finish. It validates the complete application process from end to end.
Why
End-to-end tests are important as they help ensure the system works together as a whole, from start to finish. They mimic real user scenarios, validating the system under test and its components for integration and data integrity.
How
End-to-end testing can be performed using tools like Playwright.

What
Playwright is a Node.js library developed by Microsoft to automate browser tasks. It supports all modern browsers and is capable of performing a wide array of tasks.
Why
Playwright allows developers to write tests that automate the browser, validating the web application's entire flow. It helps to ensure that all components of the application work together as expected in the real world.
