Broad, fast migration risks introducing bugs. +- A focused pilot on the simplest project (Domain.Tests) identifies tooling gaps, documentation needs, and performance impact before rolling out to larger suites. +- Pilot experience informs migration strategy for other projects (some may benefit from v3 earlier; others may require custom adapters). + +**Why now?** +- Sprint 7 roadmap (Gimli's xUnit work) already plans Domain.Tests migration; this ADR formalizes rationale and rollout strategy. +- Waiting further increases technical debt; v2 will be unsupported within 2–3 years. + +**Why incremental adoption?** +- Minimizes risk: if pilot uncovers critical issues, only one small project is affected. +- Allows team learning: developers get hands-on experience with v3 API before tackling larger projects. +- Enables data-driven decisions: performance data from Domain.Tests informs prioritization for remaining projects. + +## Consequences + +### Positive + +- **Ecosystem alignment** — Adopts modern testing platform;

dual maintenance burden until all projects migrate + +### Mitigation + +- **Document migration process** — Create wiki/guide for v3 API changes; include before/after code examples +- **Incremental rollout** — Pilot validates process;

Working as **Gimli** (Tester) 🪓 Closes #163 ## Changes | File | Change | |------|--------| | `Directory.Packages.props` | Added `xunit.v3 3.2.2` alongside existing `xunit 2.9.3` (other projects unaffected) | | `tests/Domain.Tests/Domain.Tests.csproj` | Replaced `xunit` → `xunit.v3` package reference; added `xunit.runner.json` as content | | `tests/Domain.Tests/xunit.runner.json` | New: v3 runner config (parallel execution, method display, no diagnostics) | **Zero source changes required** — the 42 test files use simple `[Fact]`/`[Theory]` patterns with no `ITestOutputHelper`, `IAsyncLifetime`, or collection fixtures. The `Xunit` namespace is unchanged in v3. ## Test Results | Suite | Result | |-------|--------| | Domain.Tests (xUnit v3) | ✅ 42/42 pass | | Architecture.Tests | ✅ 11/11 pass | | Web.Tests | ✅ 105/105 pass | | Web.Tests.Bunit | ✅ 61/61 pass | ## Notes - `xunit.runner.visualstudio 3.1.5` was already in place and is v3-compatible — no change needed. - NuGet change from #162 was folded into this PR since #162 had no commits beyond the sprint base.
