WalkthroughThis change adds UTS-derived .NET REST unit tests across authentication, REST requests, channels, presence, push, and SDK types. It also updates UTS documentation with test instructions, coverage limits, and recorded deviations. Changes.NET REST UTS test coverage
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~60 minutes Change: Other Merge Risk: 🔵 Low · up to This change adds REST unit tests and documentation without changing SDK behavior. One test changes shared global state, which can make other tests fail intermittently. Another test accepts nearly any error message, so it does not check the behavior it is meant to protect. Several documentation counts and cross-references also need correcting. These are small follow-ups and do not block merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Make the REC test counts agree.
Line 69 says 16 tests cannot be expressed. The table rows that cannot be expressed add up to 8 + 2 + 3 + 1 = 14. The REC1c1/REC1d2 row has 2 tests, but those tests compile. Line 79 says 28 of 43 fallback.md tests are translated, so 15 are left. The PR description also says 15 of 43. Line 357 of deviations.md repeats the claim of 16 tests that "cannot be written at all". Correct the totals so that the table, the prose, and deviations.md match.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The RSC1b assertion accepts almost any error message.
The test passes when the message contains "key", "auth" or "options". Nearly every AblyException from options validation contains "options", so the check passes even when the reported error does not name the missing authentication method. The assertion does not check what RSC1b requires. Assert code 40106. If the SDK does not raise 40106, assert the exact constructor-path message and record the gap as a deviation.

The global LocalDevice.Instance mutation can race with parallel test classes.
This test sets the static LocalDevice.Instance and restores it afterwards. xUnit runs test classes in different collections in parallel. Push tests that read the same static can therefore see FakeMobileDevice while this test runs. Put this class in a non-parallel collection, or in the same collection as the push tests.

Fix the stale class summary: RSC18_BasicAuthOverHttpRejected is a [Fact].
The summary lists RSC18_BasicAuthOverHttpRejected as a [DeviationFact]. On Line 346 the test is a [Fact]. The comment on Lines 354-370 says the behavior is "not a deviation", and the PR objectives say the RSC18 deviation was withdrawn. As a result, the summary gives the wrong count of env-gated tests.

Thirty-one of the forty-one uts/rest/unit spec files, covering the client, raw requests, fallback hosts, stats, logging, channels, publish, history, idempotency, channel attributes, encoding, the type specs, the whole of auth, all four push files and rest_presence. Everything runs off MockHttpClient; nothing reaches the network. Measured on net6.0: 407 passing, 29 either env-gated as SDK deviations or skipped for msgpack. The ten files not translated are absent client API rather than failing behaviour - message mutation, annotations, batch publish, token revocation - and in C# a test calling a method that does not exist is a compile error rather than a skippable test. The next commit tabulates them with their reason. The passing tests are the least interesting part of this. What the translation found is recorded alongside it, and each finding was pushed to a mechanism in product code before being written down, because a false deviation sends someone to fix a non-bug. The sharpest: StatusAsync sends the channel name unescaped. HttpChannel builds its base path with EncodeUriPart and then one method ignores it and concatenates the raw name - the only raw-name path concatenation in product code. A channel named a/b emits two path segments and hits a different endpoint, and a passing sibling pins the correct spelling on the history path, so the SDK contradicts itself. An unknown response content type crashes. RSC8e2 requires statusCode 400 and code 40013; JsonHelper.Deserialize(null) raises a raw ArgumentNullException out of the public API instead, escaping the AblyException contract entirely. ErrorCodes.InvalidMessageDataOrEncoding is declared and never raised. The push device-authentication header has the name RSH6a explicitly calls the mistaken one. The server reads the header name, so this is not cosmetic. A token string returned by an authCallback is only ever read as a TokenRequest. RSA8d allows three shapes - a token string, a TokenDetails, a TokenRequest - and the string branch is routed straight into JSON deserialisation, so a JWT fails to parse and the request dies with 80019. Three suspicions did not survive being checked and are recorded as what they turned out to be, which is the part most worth a second opinion. RSC18 was withdrawn as a translation bug: the SDK does reject basic auth over plain HTTP, just lazily, on the first authenticated request rather than at construction, and neither RSC18 nor RSA1 mandates a constructor check. RSL1k's mixed-id batch expectation and RSL6a's json/base64 chain are both UTS spec errors - an SDK that changed to satisfy either would become less compliant, not more. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Two documents start here, and both grow a section per tier as the tiers land. deviations.md is where a mismatch between the spec and the SDK goes once it has been chased to a mechanism in product code. It has five sections and the distinction between them is the whole point: a UTS spec error, a genuine SDK defect, a test adapted to this SDK's idiom, a limit of the mock harness, and a suspicion that turned out to be nothing. Only the second kind is a bug. Writing a translation mistake down as an SDK defect would send someone to fix behaviour that is already correct, so each entry names the file and line it was confirmed in. Every SDK defect keeps its spec-correct assertion in the suite as a [DeviationFact], skipped by default and runnable with RUN_DEVIATIONS=1. That makes the record checkable rather than a claim: run the suite that way and each gated test must still fail. Deleting the assertion instead would have left nothing to re-check when the behaviour is fixed. coverage.md is the other half - what was not translated and why, file by file, so that "31 of 41 spec files" is readable as something other than an unexplained gap. The common reason is absent client API: in C# a test calling a method that does not exist will not compile, so those specs cannot be written as skipped tests the way a dynamic language would. The README gains the sections those two documents make sense of, and nothing about tiers that have not arrived. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Six PRs, each based on the one before it. Review in order.
uts-to-csharptranslation skillGoal
Translate the REST half of the UTS unit tier, and record what the translation found.
Two commits: the tests, then the two documents that make the result readable.
What's added
Thirty-one of the forty-one
uts/rest/unitspec files — the client, raw requests, fallbackhosts, stats, logging, channels, publish, history, idempotency, channel attributes, encoding, the
type specs, the whole of auth, all four push files and
rest_presence.Everything runs off
MockHttpClient; nothing reaches the network. Measured onnet6.0: 407passing, 29 either env-gated as SDK deviations or skipped for msgpack.
Uts/deviations.mdandUts/coverage.mdstart here, and each later tier adds its own sectionto them.
deviations.mdis where a mismatch between the spec and the SDK goes once it has been chased to amechanism in product code. It has five sections and the distinction between them is the whole
point: a UTS spec error, a genuine SDK defect, a test adapted to this SDK's idiom, a limit of the
mock harness, and a suspicion that turned out to be nothing. Only the second kind is a bug. Writing
a translation mistake down as an SDK defect would send someone to fix behaviour that is already
correct, so every entry names the file and line it was confirmed in.
coverage.mdis the other half — what was not translated and why, file by file. The ten files nottranslated are absent client API rather than failing behaviour (message mutation, annotations,
batch publish, token revocation), and in C# a test calling a method that does not exist is a
compile error rather than a skippable test.
What the translation found
Each finding was chased to a mechanism in product code before being written down, because a false
deviation sends someone to fix a non-bug. The sharpest four:
StatusAsyncsends the channel name unescaped.HttpChannelbuilds its base path withEncodeUriPartand then this one method ignores it and concatenates the raw name — the onlyraw-name path concatenation in product code. A channel named
a/bemits two path segments and hitsa different endpoint. A passing sibling pins the correct spelling on the history path, so the SDK
contradicts itself.
An unknown response content type crashes. RSC8e2 requires
statusCode400 and code 40013;JsonHelper.Deserialize(null)raises a rawArgumentNullExceptionout of the public API instead,escaping the
AblyExceptioncontract entirely.ErrorCodes.InvalidMessageDataOrEncodingisdeclared and never raised.
The push device-authentication header has the name RSH6a explicitly calls the mistaken one. The
server reads the header name, so this is not cosmetic.
A token string returned by an
authCallbackis only ever read as aTokenRequest. RSA8d allowsthree shapes — a token string, a
TokenDetails, aTokenRequest— and the string branch is routedstraight into JSON deserialisation, so a JWT fails to parse and the request dies with 80019.
Three suspicions that did not survive being checked
This is the part most worth a second opinion, because each one looked like a defect and is not:
lazily — on the first authenticated request rather than at construction. Neither RSC18 nor RSA1
mandates a constructor check.
An SDK that changed to satisfy either would become less compliant, not more.
Caveat
Every SDK defect keeps its spec-correct assertion in the suite as a
[DeviationFact], skipped bydefault and runnable with
RUN_DEVIATIONS=1. That makes the record checkable rather than a claim:run the suite that way and each gated test must still fail. Deleting the assertion instead would
have left nothing to re-check when the behaviour is fixed.
