Software Construction Fundamentals: Abstraction, OOP, and Testing

Writing code that works is only the first step; writing software that is easy to understand, change, and maintain is the real challenge for developers. This text-based course guides you through the foundational principles of software construction, helping you transition from writing simple scripts to designing robust, production-ready software systems. What you'll learn: - Understand core programming paradigms, including object-oriented programming, functional programming, and state machines - Design clear abstractions and interfaces to achieve modularity and decouple complex systems - Apply modern design patterns to bridge the gap between abstract concepts and clean, executable code - Write robust specifications and use invariants to reason about code correctness and prevent bugs - Implement comprehensive testing strategies, including automated unit tests, test-case generation, and code coverage - Leverage modern type systems and code formatting practices to ensure long-term maintainability This course begins with key terminology, basic concepts, and foundational definitions before moving into practical design patterns, specifications, and testing methodologies. You will learn entirely through reading detailed explanations, analyzing clean code snippets, and completing conceptual exercises. Designed for beginner programmers who want to elevate their coding practices, this course requires only a basic familiarity with programming.
