Test Driven Development with C# - from Padawan to Jedi
summary
Shows practical TDD in C# with live coding: writes failing tests, uses red green refactor, then refactors an EmployeeValidator into a record and passes xUnit-style tests using FluentAssertions. Distinguishes unit/integration/end-to-end tests, explains tradeoffs (speed, determinism, external deps), suggests testing behavior not implementation, and applies Checkov’s gun to trim test setup. Demo compiles, produces NotImplemented failure first, then green tests, and stays focused on small iterations rather than big upfront design.
