+# Backend tests
+
+The normal test command remains Docker-free:
+
+```powershell
+dotnet test Nexus.Api.Tests.csproj --configuration Release
+```
+
+Docker-backed tests are discovered but skipped unless explicitly enabled.
+They use `postgres:17-alpine`; the optional network-fault contract additionally
+uses Testcontainers Toxiproxy and a pinned lightweight OpenClaw HTTP stub.
+
+```powershell
+$env:NEXUS_RUN_DOCKER_INTEGRATION_TESTS = "true"
+dotnet test Nexus.Api.Tests.csproj --configuration Release `
+  --filter "Category=DockerIntegration"
+```
+
+Enable the slower Toxiproxy case as well:
+
+```powershell
+$env:NEXUS_RUN_DOCKER_INTEGRATION_TESTS = "true"
+$env:NEXUS_RUN_TOXIPROXY_INTEGRATION_TESTS = "true"
+dotnet test Nexus.Api.Tests.csproj --configuration Release `
+  --filter "Category=DockerIntegration"
+```
+
+Once opted in, an unavailable Docker daemon is a test failure rather than a
+silent skip. In Gitea Actions, set the repository variable
+`NEXUS_RUN_DOCKER_INTEGRATION_TESTS=true`; optionally set
+`NEXUS_RUN_TOXIPROXY_INTEGRATION_TESTS=true` for the timeout contract. The
+selected runner must expose a working Docker endpoint to Testcontainers.
