DotNetTests

Six .NET test frameworks side-by-side, tested against the same code: a Calculator, an Aspire-orchestrated WebApp + ApiService, a Blazor Counter component.

Use this repo to read the same test written six different ways.

AdvancedPatterns/ is the extra study project: reusable contract tests, in-memory protocol hosts, deterministic call expectations, JSON workflow harnesses, and adversarial file-store tests.
