🚀 Introduction to Mocking & Stubbing in Cypress with TypeScript | E2E Testing Tutorial | Ep 01

Welcome to the first video in our Cypress and TypeScript testing series! 🎬 In this tutorial, we’ll dive into the foundational concepts of mocking and stubbing—essential techniques for isolating your tests, controlling external dependencies, and writing reliable end-to-end (E2E) tests. Whether you're new to testing or looking to level up your Cypress skills, this video is your gateway to mastering these powerful tools. What You’ll Learn: What Are Mocking & Stubbing? Clear definitions and real-world analogies to understand why these techniques matter. The difference between mocking, stubbing, and spying (and when to use each). Setting Up Cypress with TypeScript Quick setup guide for integrating Cypress into a TypeScript project. Configuring TypeScript for optimal test development. Basic Mocking with cy.intercept() How to mock API requests (GET, POST) using Cypress’s built-in cy.intercept() method. Simulate responses with custom status codes, headers, and JSON data. Practical Stubbing Examples Replace third-party API calls with controlled stubs. Use fixtures to mock data for consistent and repeatable tests. Best Practices for Beginners Avoiding common pitfalls in mocking and stubbing. Writing clean, maintainable tests that scale with your application. Why Mocking & Stubbing? Isolate Tests: Remove dependencies on external APIs or services. Control Scenarios: Test edge cases like network errors, slow responses, or invalid data. Speed Up Testing: Skip waiting for real APIs to respond. Improve Reliability: Ensure your tests aren’t flaky due to external factors. Who Is This Video For? Developers starting their journey with Cypress and TypeScript. QA Engineers aiming to write more robust E2E tests. Tech Leads who want to enforce best practices in their team’s testing workflow. Anyone curious about modern testing techniques! Prerequisites: Basic knowledge of JavaScript/TypeScript. Familiarity with Cypress (check out our Cypress Setup Guide if you’re new!).
