Property-Based Testing File Structure with PropEr

Scaling your test suites requires more than just writing tests; it demands a clean, organized structure that keeps your codebase maintainable. If you want to move beyond basic unit testing in Erlang, understanding how to systematically lay out your property-based tests is the essential next step. This text-only course guides you through the foundational concepts of property-based testing, showing you exactly how to organize your test files, write clean properties, and build custom generators using the PropEr framework. You will transition from writing disorganized test scripts to structuring production-ready test suites. What you'll learn: - Understand the core principles of property-based testing and how PropEr operates. - Organize your Erlang test files and directories systematically using modern build tools like rebar3. - Define clear properties and helper functions that keep your test code clean and maintainable. - Create custom generators to model complex data structures and edge cases. - Integrate your PropEr test suite into modern development and continuous integration workflows. You will start with the fundamental terminology of properties and generators before diving into hands-on directory layouts. Through written explanations and clear code examples, you will learn to structure helpers, configure test targets, and manage complex test suites. This course is designed for Erlang developers who are new to property-based testing or want to improve their test suite organization. No prior experience with PropEr is required.
