DRY TDD with AutoFixture
summary
Shows using AutoFixture to remove test setup duplication by applying anonymous data, equivalent sets and a test data builder. Implements Conway’s Game of Life underpopulation rule with three TDD tests (compile fail, minimal green, then rule) and then replaces manual construction with AutoFixture customizations to create one alive solitary cell. Tests become smaller, decoupled from constructors, still pass, and allow changing the API (for example to params) without breaking the test suite.
