DTT favors honest feedback with the least necessary test machinery. The canonical attribute/context matrix lives in drn-testing.
| Principle | Practice |
|---|---|
| Security first | Avoid leaking secrets in fixtures, logs, snapshots, and generated data |
| Correctness over speed | Prefer real dependencies when mocks would hide behavior |
| Clarity over cleverness | One readable flow beats many tiny duplicate tests |
| Simplicity | Use [Fact] when no data, generation, or context is needed |
| Performance with proof | Benchmark only when a performance question is explicit |
| Change | Default test type | Why |
|---|---|---|
| Pure utility, domain invariant, deterministic branch logic | Unit | No container value; use DataInlineUnit when data/generation helps |
| Attribute DI registration or isolated service behavior | Unit | DrnTestContextUnit validates wiring without Docker |
| Repository, EF mapping, query, transaction, concurrency | Integration DB | Real PostgreSQL is the useful signal |
| Controller, endpoint, auth, middleware, serialization | API integration | Full request pipeline via ApplicationContext |
| External HTTP client behavior | Integration/API | Use FlurlHttpTest against outbound URL patterns |
| Throughput, allocation, latency, load | Performance | BenchmarkDotNet/K6 only with explicit user intent |
