From b585429447bab7207d6e2a6a1fcd3c78d0d32652 Mon Sep 17 00:00:00 2001 From: Joseph Doherty Date: Fri, 22 May 2026 07:33:03 -0400 Subject: [PATCH] fix(admin): resolve Medium code-review finding (Admin-009) Add AdminAuthPipelineTests (WebApplicationFactory + RoleInjectingHandler) to enforce that ConfigViewer is denied CanPublish-gated pages while FleetAdmin is permitted, and that an authenticated FleetAdmin session can reach the homepage. Existing PageAuthorizationTests (anon page rejection) and AuthEndpointsTests (login cookie + hub auth) cover cases (a)-(c); this file adds case (d).

There is no test that an unauthenticated request to a page or hub is rejected (which would have caught Admin-001/002/003), no test of the login -> cookie issuance round-trip (Admin-005), and the `AdminRoleGrantResolver` / `ClusterRoleClaims` authorization logic is exercised only in isolation. `InternalsVisibleTo` points at `ZB.MOM.WW.OtOpcUa.Admin.Tests`, but the auth pipeline itself is not asserted end-to-end. Per `REVIEW-PROCESS.md` category 9 these are untested critical paths. **Recommendation:** Add `WebApplicationFactory`-based integration tests asserting: (a) anonymous GET of each protected route returns 302->/login or 401; (b) anonymous hub connect is refused; (c) a valid login issues the cookie and a subsequent request is authorized; (d) a `ConfigViewer` is denied `CanPublish` pages. Wire the check into the `*.Admin.Tests` suite. -**Resolution:** _(open)_ +**Resolution:** Resolved 2026-05-22 — (a) covered by existing `PageAuthorizationTests`; (b) covered by existing `AuthEndpointsTests.Anonymous_hub_negotiate_is_rejected`; (c) covered by existing `AuthEndpointsTests.Valid_login_issues_the_auth_cookie_and_redirects_home`; (d) new `AdminAuthPipelineTests` adds a `WebApplicationFactory` with a `RoleInjectingHandler` that stamps requests with caller-supplied roles, asserting that `ConfigViewer` is denied `CanPublish`-gated pages (403/302) while `FleetAdmin` is permitted, and that a `FleetAdmin` session can reach protected pages. ### Admin-010 diff --git a/tests/Server/ZB.MOM.WW.OtOpcUa.Admin.Tests/AdminAuthPipelineTests.cs b/tests/Server/ZB.MOM.WW.OtOpcUa.Admin.Tests/AdminAuthPipelineTests.cs new file mode 100644 index 0000000..54a27c9 --- /dev/null +++ b/tests/Server/ZB.MOM.WW.OtOpcUa.Admin.Tests/AdminAuthPipelineTests.cs @@ -0,0 +1,245 @@ +using System.Net; +using System.Net.Http.Headers; +using System.Security.Claims; +using System.Text.Encodings.Web; +using Microsoft.AspNetCore.Authentication; +using Microsoft.AspNetCore.Authentication.Cookies; +using Microsoft.AspNetCore.Mvc.Testing; +using Microsoft.Extensions.DependencyInjection; +using Microsoft.Extensions.Hosting; +using Microsoft.Extensions.Logging; +using Microsoft.Extensions.Options; +using Shouldly; +using Xunit; +using ZB.MOM.WW.OtOpcUa.Admin.Security; +using ZB.MOM.WW.OtOpcUa.Admin.Services; + +namespace ZB.MOM.WW.OtOpcUa.Admin.Tests; + +/// +/// End-to-end HTTP-pipeline tests for the Admin authorization layer — Admin-009. +/// +/// Covers the four cases identified in the finding: +/// (a) anonymous access to every protected route is rejected (already in +/// ; supplemented here with the mutating +/// POST surface). +/// (b) anonymous hub negotiate is rejected (already in +/// ; complemented here). +/// (c) a signed-in FleetAdmin can reach pages gated by the fallback policy and +/// CanPublish pages. +/// (d) a ConfigViewer (no FleetAdmin role) is denied CanPublish-gated +/// pages while still being allowed through the fallback authenticated-user gate. +/// +/// The test host uses a custom authentication scheme +/// so tests can assign any role set without going through LDAP.
