Foundations of TDD in TypeScript and Jest: The Principles
This course introduces Test-Driven Development (TDD) for TypeScript projects, covering the Red-Green-Refactor workflow, TDD mindset, and setup with Jest. Learn best practices like SOLID principles and dependency injection, and explore TDD's impact on code quality and speed compared to traditional approaches.
Red-Green-Refactor: Practicing TDD with JavaScript & Jest
This course focuses on practicing the core TDD workflow: "Red-Green-Refactor." You'll write failing tests (Red), implement code to pass them (Green), and refactor while keeping tests passing (Refactor). No new concepts are introduced—just hands-on practice with various requirements to sharpen your TDD skills.
Isolating Dependencies with Test Doubles with TypeScript & Jest
Discover the pivotal role of test doubles in modern software testing. This introductory session will guide you through the essentials of dummies, stubs, spies, mocks, and fakes. Learn how these powerful tools help you isolate units under test, control behavior, and build reliable, fast, and maintainable tests. Step into the world of test doubles and elevate your software development skills.
Refactoring by Leveraging Your Tests with TypeScript & Jest
This course focuses on the Refactor step in TDD, teaching developers to spot code smells and resolve them through refactoring. Using real-world examples, you'll identify common issues, apply refactoring techniques, and ensure functionality is preserved with existing tests.
