Form Validation with Cypress: Build Robust Web Test from Coursera

In this hands-on guided project, you’ll learn how to use Cypress, a powerful end-to-end testing framework, to ensure your web forms are user-friendly, bug-free, and robust.

We’ll be testing on a real form, simulating actual user interactions to validate form behavior, catch errors, and ensure a smooth experience.

Whether you’re a developer, tester, or product manager, this project will equip you with the skills to write automated tests for form validation and error handling, making you a more effective collaborator in building high-quality web applications.

Through step-by-step exercises, you’ll:

- Write automated tests to validate user input and ensure forms behave as expected.

- Simulate user interactions like typing, submitting, and clearing forms.

- Test error messages and handle edge cases to catch bugs early.

- Organize tests for maintainability and scalability, making them easier to update and reuse.

By the end of this project, you’ll be able to:

- Confidently write Cypress tests for complex forms.

- Test error messages for invalid emails, passwords, and credit cards.

- Organize tests with custom commands for scalability.

- Ensure your web applications provide a seamless user experience.

This project is perfect for:

- Developers who want to test their code and catch bugs early.

- Testers/QA Engineers looking to automate form validation tests.

you should have basic knowledge of JavaScript and web development is helpful but not required. No prior experience with Cypress is necessary, as we’ll cover everything step by step.
