Welcome back! We previously delved into validating shopping cart updates to ensure a seamless e-commerce experience. In today’s lesson, we’ll shift our focus to another critical component — simulating user registration and login. Proper management of user accounts is fundamental to any online store, as it ensures secure access and enhances user satisfaction. With the foundation we've built in prior lessons, we're ready to advance our skills using Playwright and TypeScript in our test automation journey.

This lesson will guide you through the processes of simulating user registration and login using Playwright’s Page Object Model (POM). We will focus on:

• Understanding how to create tests for registering new users and logging them in.
• Applying the POM to modularize and streamline test scripts for reuse and clarity.
• Validating successful user interactions by checking UI feedback.

To ease your understanding, here's a snippet that provides an overview of implementing registration and login functionality:

This example leverages abstraction through POM to maintain a clean test structure while performing registration and login operations efficiently.

User authentication is at the forefront of establishing trust with your application users. Effective registration and login simulations ensure that your users can create accounts and access them without hitches. By integrating these tests into your suite, you can identify and fix potential issues early, ultimately protecting both user satisfaction and data security.

Ready to master user interaction testing? The practice section awaits, where you will apply these concepts and refine your testing skills further, ensuring a secure and smooth user experience on your e-commerce app.
