Context

Use this when a legacy modernization issue is about wiring or composition, but the implementation has not landed yet. Tester-owned progress should protect the observable seams that a refactor must preserve rather than speculating on the future container API.

Patterns

Extend src\before\Fabrikam.EnterprisePizza.Legacy.Tests with thin, believable smoke tests instead of broad end-to-end coverage.
Cover consumer-facing seams first: the gateway alias lookup, any batch job that consumes it, and the WCF/ASMX hosts that expose business data.
Strengthen existing legacy smoke tests with explicit counts and representative values; avoid Count > 0 when the sample already has stable seeded rows.
Add direct project references for any host or contract assemblies that appear in method signatures used by the tests.
In worktrees, restore/build the old-style NUnit project with dotnet msbuild <project> /t:Restore /p:RestorePackagesConfig=true and point nunit.framework at %UserProfile%\.nuget\packages if no repo-local packages\ folder exists.
Because the repo does not include an NUnit adapter, finish with a Windows PowerShell runtime smoke pass against the built host assemblies.

Examples

src\before\Fabrikam.EnterprisePizza.Legacy.Tests\SmokeTests\LegacyDbGatewayFixture.cs
src\before\Fabrikam.EnterprisePizza.Legacy.Tests\SmokeTests\NightlyPosImportJobFixture.cs
src\before\Fabrikam.EnterprisePizza.Legacy.Tests\SmokeTests\StoreDispatchServiceFixture.cs
src\before\Fabrikam.EnterprisePizza.Legacy.Tests\SmokeTests\PartnerSyncServiceFixture.cs

Anti-Patterns

Writing tests that assert a specific DI container API before the implementation exists.
Expanding the legacy smoke project into broad integration coverage.
Relying on a repo-local src\before\packages\ folder when the worktree restores NUnit into the user NuGet cache.
Declaring the seam protected after a compile-only pass without running a host-level runtime smoke check.
