Each block is +self-contained but non-trivial: + +1. **Aggregate – Base** (32 stubs) + **Historical Access {Insert, Delete, Read} Value** (59 logic-tests) + - Port `AggregateHelper.PerformSingleNodeTest` with its config/time/processing-interval enums. + - Implement `CUVariables` equivalent (test data registration). + - Effort: 1 week for the helper, 2-3 days to wire all 91 tests. + +2. **GDS Application Directory / LDS-ME Connectivity** (33 stubs) + - Need a working LDS or local discovery server in the test fixture. + - Port CTT's GDS helper. + - Effort: 1-2 weeks. + +3. **Security User {Anonymous, X509, NamePwd}** (~38 stubs + logic) + - Each is mostly endpoint discovery + activate-session with a specific token. + - Effort: medium; share helpers across the three families. + +4. **Security Certificate Validation / Policy Support** (~24 stubs) + - Need test fixtures that publish multiple endpoints with each policy. + - Effort: medium-high. + +### Tier C — Server-mock required (target: 72 stubs) + +These tests rely on injecting bad responses (`ServiceResult: BadFoo` or +`response.X = mutated`). Real OPC UA clients cannot trigger these conditions against +a well-behaved server. Two options: + +- **Option C1**: Build a configurable proxy/stub OPC UA server that lets a test + configure the response it should produce for the next request. NUnit fixtures + spin up the stub and exercise the failure path. + - Effort: 2-3 weeks for the proxy infrastructure, then 1-2 days per test family. + +- **Option C2**: Leave them as `Assert.Ignore` and document the limitation. + - Effort: zero. README already lists them as ⏭️. + +**Recommendation**: Option C2 unless a stakeholder explicitly wants Option C1. + +### Tier D — Conditional-skip refinements (target: 351 logic-with-Ignore tests) + +These are real tests that gracefully skip when a prerequisite is missing. Two paths +to convert them to `Assert.Pass`/`Assert.Fail`: + +1. **Add the missing feature to the reference server** so the prerequisite is always + satisfied (preferred for OPC UA-mandatory features). +2. **Hard-fail when the prerequisite is absent** if the conformance unit treats the + prerequisite as mandatory. + +Top blocks: + +| Unit | Count | Strategy | +|---|---:|---| +| Historical Access Insert/Delete/Read | 59 | Tier B helper port enables most. | +| Node Management Add/Delete | 25 | Already partially implemented after May 3 work; revisit residual skips. | +| Security Role Server * | 39 | Implement role/identity management on reference server (existing stub in `RoleManagementHandler`). | +| Push Model GDS | 9 | Tier B GDS port. | +| Address Space Notifier Hierarchy | 9 | Add notifier hierarchy nodes to AlarmNodeManager. | +| Data Access Analog/MultiState | 15 | Add missing properties (EuRange, EngineeringUnits) to ReferenceNodeManager. | +| Security None / Basic 128Rsa15 / 256 / Aes / Sha256 | 50 | Configure endpoint per policy, skip-or-fail consistently. | +| A&C Shelving / Refresh2 | 11 | Set `optional: true` in `AlarmNodeManager.CreateAlarm` calls so ShelvingState/SuppressedState exist on alarm holders. | +| AliasName Base | 7 | Already partially implemented; review residual. | +| Subscription Minimum 02 | 7 | Verify timing/reliability assumptions. | +| Auditing Secure Communication | 4 | Need server endpoint with security to drive audit events. | + +## Phased execution roadmap + +| Phase | Scope | Outcome | +|---|---|---| +| 1 (done) | Delete 34 unmappable stubs; refresh README. | -34 stubs. | +| 2 | Tier A: Base Info methods, AliasName residuals, Address Space simple checks. | -50 stubs / -10 logic-skips. | +| 3 | Tier B-1: Aggregate helper port + Historical Access. | -32 stubs / -59 logic-skips. | +| 4 | Tier B-3: Security User token families. | -38 stubs. | +| 5 | Tier B-2: GDS Application Directory / LDS-ME. | -33 stubs. | +| 6 | Tier D: Role server, Push, Notifier, DA Analog/MultiState, A&C optional features. | -83 logic-skips. | +| 7 | Tier C decision: server-mock (or close as documented limitation). | -72 stubs (kept as Ignore with explanation). | + +## Open questions / decisions + +- **Server-mock infrastructure**: do we want it (Tier C, Option C1)?
