This course contains the use of Artificial Intelligence." Unofficial Course "In today’s fast-paced software industry, building reliable, maintainable, and scalable software requires more than simply writing code—it requires adopting disciplined engineering practices that prioritize quality from the beginning. This course is designed to provide a comprehensive understanding of Test-Driven Development (TDD) as both a technical methodology and a software engineering mindset that transforms the way modern systems are designed, developed, and maintained.Throughout this course, you will explore the historical evolution of software quality assurance and understand why Test-Driven Development has become a central practice in modern software engineering environments. You will learn the philosophical foundations behind TDD, examine the Red-Green-Refactor cycle in depth, and understand how test-first thinking changes the architecture and maintainability of software systems.The course goes beyond basic testing concepts by exploring what makes tests effective, maintainable, and valuable over time. You will study the structural principles behind testable code, learn how dependency management influences software design, and understand how concepts such as test doubles, mocks, stubs, and fakes contribute to building isolated and reliable test environments. Additionally, you will explore how TDD aligns with widely accepted design principles such as SOLID and supports cleaner, more modular architectures.You will also gain a deep understanding of the relationship between Test-Driven Development and Behavior-Driven Development (BDD). The course explains how business requirements can be translated into technical specifications, how shared communication models improve collaboration across teams, and how modern development organizations bridge the gap between technical implementation and stakeholder expectations.Advanced top

AI agents are how software gets built next. This course teaches you to build them — from scratch, in Python, using the Claude Agent SDK.The Claude Agent SDK is the same technology that powers Claude Code — Anthropic's AI coding assistant used by hundreds of thousands of developers worldwide. This course gives you programmatic access to that same engine, so you can build autonomous agents that read files, run commands, search the web, ask users questions, and complete complex multi-step tasks — without writing a single line of tool execution logic yourself.What You Will BuildBy the end of this course you will have built three complete agents from scratch:File Explorer Agent — autonomously explores a directory, reads every file, and produces a clean summary report. Your first complete autonomous agent.Codebase TODO Summarizer Agent — searches an entire codebase for TODO comments, filters results by priority based on your preferences, and produces a structured report. Uses Glob, Grep, Read, and AskUserQuestion working together.Safe Code Review Agent — the course capstone. Reviews code for quality issues and security vulnerabilities — hardcoded credentials, SQL injection, poor error handling — without being able to modify a single file. Three layers of production safety built in.What You Will LearnSection 1 — The Big Picture Understand exactly how the Claude Agent SDK works under the hood before writing a single line of code. The four components, the agent loop, pipe communication between the SDK and Claude Code, and session management. This mental model makes everything else in the course click.Section 2 — Your First Agent Everything runs in Google Colab — no local setup required. Write your first query() call, master async/await in Python, read and filter the agent message stream, and build your firs
