Elixir Property Testing: Custom Data Generation

Writing reliable software requires comprehensive testing, but traditional unit tests often miss edge cases. Property-based testing offers a powerful approach, and its effectiveness hinges on generating the right data. This course guides you through the process of designing and implementing custom data generators in Elixir, allowing you to precisely control the distribution and characteristics of test inputs. You will gain the skills to create more intelligent and effective tests that uncover subtle bugs. What you'll learn: * Understand the core principles and benefits of property-based testing. * Learn to define basic and custom data generators using Elixir's testing tools. * Apply probabilistic techniques to guide data generation towards specific scenarios. * Explore strategies for combining and composing complex data generators. * Practice shrinking generated data to pinpoint the root cause of test failures. * Write targeted property tests that thoroughly validate Elixir application logic. The course begins with an introduction to property-based testing concepts and the basics of data generation. It then progresses to defining custom generators, applying probabilistic controls, and mastering advanced techniques for composing generators and interpreting test results through shrinking. This course is designed for beginner Elixir developers and testers looking to enhance their testing skills. No prior experience with property-based testing is required.
