Learn about the power of internal shrinking in property-based testing through this conference talk from ElixirConf EU 2024. Explore how shrinking produces small, human-readable test cases from larger random cases when tests fail. Discover why traditional shrinking approaches, which require specific knowledge of data types, can break when generated values are mapped or combined. Understand the concept of internal shrinking, where reducing the source of randomness automatically simplifies test cases through generators. Get introduced to the Decorum library for Elixir, which implements seamless property-based testing with built-in shrinking capabilities.
