Organizing Go Programs: Directory Structure and Testing Foundations

Writing Go code is easy, but organizing a growing codebase so it remains maintainable and testable is a common challenge for developers. This text-based course teaches you how to structure your Go applications following industry-standard patterns. You will transition from writing single-file scripts to architecting clean, modular Go applications. Through clear written explanations and practical code snippets, you will learn how to design command-line tools, split code into logical packages, and write robust automated tests. What you'll learn: - Understand foundational Go concepts, including module initialization and package visibility rules. - Design clean directory structures using standard Go layout patterns like the cmd and internal directories. - Build modular command-line interface (CLI) applications that are easy to maintain and extend. - Write effective unit tests and table-driven tests using Go's built-in testing package. - Apply modern Go practices, including dependency management with Go modules and proper error handling. The course begins with core Go terminology and module setup before moving step-by-step into package organization, command-line design, and automated testing strategies. You will read through practical examples and reinforce your learning with written architecture exercises. This course is designed for beginners who know basic Go syntax and want to learn how to structure real-world projects; no prior experience with software architecture or testing is required.
