Advanced Playwright TypeScript Tutorial | Code Generation | Part II | LambdaTest

About The Video

In this Part 2 of the advanced Playwright TypeScript tutorial, join 𝐕𝐢𝐠𝐧𝐞𝐬𝐡 𝐒𝐫𝐢𝐧𝐢𝐯𝐚𝐬𝐚𝐧, Udemy Instructor and Software Quality Engineer at N26, as he dives into the concept of code generation in Playwright, a feature that automatically generates test scripts based on actions performed in the browser.

Learn how Playwright captures browser events, such as logging in, entering credentials, and clicking buttons, to convert these actions into testable code. This powerful feature simplifies end-to-end automation, allowing users to quickly automate complex workflows without needing to be experts in Playwright or TypeScript.

Introduction to Code Generation in Playwright:

Overview of Playwright's code generation feature.

How it captures user actions in the browser and converts them into a Playwright script.

Advantages of Code Generation:

Simplifies automation of end-to-end flows.

Suitable for beginners with limited knowledge of Playwright or programming languages.

Reduces initial setup time for test automation.

Disadvantages of Code Generation:

Not suitable for large projects with multiple modules.

Generates raw, less maintainable code.

Inefficient locator strategies that may not adhere to best practices.

Setting Up Playwright and LambdaTest Integration:

Customizing build names for easier debugging based on browser and test names.

Configuring the package.json file to run tests for specific browsers and operating systems.

Using Playwright Code Generation:

Command: npx playwright codegen to trigger code generation.

Generated scripts based on browser actions.

Examples of using the tool to automate login flows and other website interactions.
