Property-Based Testing in Elixir with PropEr Generators

Are you tired of writing tests that only cover happy paths and miss subtle edge cases? Traditional examples-based testing often falls short in uncovering unexpected bugs. Property-based testing offers a powerful alternative, allowing you to define the expected behavior of your code rather than specific inputs. This course will equip you with the fundamental skills to implement robust, data-driven tests for your Elixir applications using PropEr. You will significantly improve your code quality, catch elusive bugs, and build more resilient software by exploring the art of generating comprehensive test data. What you'll learn: * Understand the core principles and advantages of property-based testing. * Apply PropEr to define and check properties for various Elixir functions and modules. * Leverage PropEr's powerful default generators to produce varied and relevant test data. * Customize and compose generators to create complex and stateful testing scenarios. * Interpret test failures and utilize shrinking to identify minimal counterexamples. * Integrate property-based tests into your Elixir development workflow for continuous quality. Beginning with a clear explanation of property-based testing concepts, this course progressively guides you through PropEr's generator system, practical application, advanced customization techniques, and finally, how to incorporate these tests effectively into your development process. This course is designed for beginner Elixir developers and testers who want to enhance their testing strategies. No prior experience with property-based testing is required.
