The string codes are duplicated between the factory and the inline calls; tests assert against the inline codes. - StorageUnavailable, SearchUnavailable, StorageFailed, DeleteFailed, InvalidStateTransition, MessageBrokerUnavailable (both overloads): only referenced in XML doc comments in DocumentEndpoints.cs, never invoked. BatchErrors (deleted entirely): - PathRequired, InvalidPath, PathsNotDistinct, InvalidTimeZone: zero references anywhere. BatchOptions validation is handled inline in ServiceCollectionExtensions via AddOptionsWithValidateOnStart. Per CLAUDE.md: 'delete a file outright when the codebase is healthier without it.'

Drives them via two new integration tests that mint a fresh `test-{Guid.NewGuid():N}` index per test and construct their own SearchIndexService (DI gives the fixture-bound singleton): - Branch (b): two concurrent IndexDocumentAsync calls on a unique index race the outer ContainsKey check, the semaphore serializes them, and the second caller hits the inner ContainsKey and short-circuits. Proved by asserting the "Created Elasticsearch index" log fires exactly once via FakeLogger. - Branch (c): pre-create the index out-of-band, then assert InitializeAsync finds Exists == true and emits no create-log. The document is still indexed successfully against the pre-existing index. A third test pins the "don't fake it" contract for null createdAt: the field is absent from the persisted _source rather than substituted with processedAt. PaperlessServices/Host/Extensions/ServiceCollectionExtensions.cs's no-arg AddOcrServices() and AddGenAiServices(IConfiguration) were unreachable from the integration fixture (which uses the IConfiguration overload). A new unit-test class covers them in isolation, plus the MinIO endpoint parsing branches (schemeless host:port vs. full URI) and UseSsl=true. --- .../SearchIndexConcurrencyTests.cs | 151 ++++++++++++ .../Unit/ServiceCollectionExtensionsTests.cs | 215 ++++++++++++++++++ 2 files changed, 366 insertions(+) create mode 100644 PaperlessServices.Tests/Integration/SearchIndexConcurrencyTests.cs create mode 100644 PaperlessServices.Tests/Unit/ServiceCollectionExtensionsTests.cs diff --git a/PaperlessServices.Tests/Integration/SearchIndexConcurrencyTests.cs b/PaperlessServices.Tests/Integration/SearchIndexConcurrencyTests.cs new file mode 100644 index 0000000..67ed117 --- /dev/null +++ b/PaperlessServices.Tests/Integration/SearchIndexConcurrencyTests.cs @@ -0,0 +1,151 @@ +namespace PaperlessServices.Tests.Integration; + +/// +/// Integration tests targeting the InitializeAsync concurrency branches in +/// that the standard +/// suite does not exercise. +/// +/// +/// +/// caches initialized index names in a static +/// +/// shared across instances.

delete unreachable XmlException branch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit DocumentService.cs gaps closed (100% line/branch): - UploadDocumentAsync: added test for unknown storage exception type that TryMapStorageException returns null for; asserts the original exception propagates uncaught (covers the `throw;` re-raise branch). - ProcessOcrResultAsync: added two tests for the transitionResult.IsError short-circuit (lines 148-151): one with an already-Completed document (Document.CannotComplete), one with an already-Failed document (Document.CannotFail). Asserts MockBehavior.Strict on the repository to prove UpdateAsync is NOT called when the state transition fails. ReportProcessor.cs gaps closed: - Added ProcessAsync_DateWithTimezone test: '2024-01-15+02:00' satisfies xs:date schema validation but fails DateOnly.TryParseExact('yyyy-MM-dd'), exercising the InvalidDate factory at lines 100-103. - DELETED the `catch (XmlException ex)` branch (lines 125-127) as unreachable: XmlSerializer.Deserialize wraps both XmlException and XmlSchemaException as InvalidOperationException before the catch chain sees them. Verified by writing a test against empty/malformed content and observing it always hits InvalidOperationException → InvalidSchema. - DELETED the corresponding ReportErrors.InvalidXml factory (sole caller was the deleted catch block). DTOs.cs (UploadDocumentRequest) gap closed: - New UploadDocumentRequestDtoTests.cs covers the synthesized record copy-constructor used by 'with' expressions (was the 50% uncovered half; the File property is exercised by every upload test). All 350 tests in PaperlessREST.Tests pass. --- .../Unit/DocumentServiceTests.cs | 84 +++++++++++++++++++ .../Unit/ReportProcessorTests.cs | 31 +++++++ .../Unit/UploadDocumentRequestDtoTests.cs | 47 +++++++++++ .../Application/ReportErrors.cs | 4 - .../Application/ReportProcessor.cs | 7 +- 5 files changed, 165 insertions(+), 8 deletions(-) create mode 100644 PaperlessREST.Tests/Unit/UploadDocumentRequestDtoTests.cs diff --git a/PaperlessREST.Tests/Unit/DocumentServiceTests.cs b/PaperlessREST.Tests/Unit/DocumentServiceTests.cs index 6f5dcdc..88966a2 100644 --- a/PaperlessREST.Tests/Unit/DocumentServiceTests.cs +++ b/PaperlessREST.Tests/Unit/DocumentServiceTests.cs @@ -598,4 +598,88 @@ public async Task DeleteDocumentAsync_SearchDeleteFails_LogsWarning() l.Level == LogLevel.Warning && l.Message.Contains("search index", StringComparison.OrdinalIgnoreCase)); } + + // ═══════════════════════════════════════════════════════════════ + // TESTS: UploadDocumentAsync - Unknown Storage Exception (rethrown) + // Covers DocumentService.cs lines 107-108 (TryMapStorageException returns null → throw) + // ═══════════════════════════════════════════════════════════════ + + [Fact] + public async Task UploadDocumentAsync_UnknownStorageException_PropagatesOriginalException() + { + // Arrange — an exception type not handled by TryMapStorageException + UploadDocumentRequest request = UploadDocumentRequestBuilder.ValidPdf().Build(); + InvalidOperationException expected = new("Unknown infrastructure failure"); + + _storage.Setup(s => s.UploadAsync( + It.IsAny(), + It.IsAny(), + It.IsAny(), + It.IsAny())) + .ThrowsAsync(expected); + + DocumentService sut = CreateSut(); + + // Act + Func act = () => sut.UploadDocumentAsync(request, TestContext.Current.CancellationToken); + + // Assert — original exception propagates to caller, not mapped to ErrorOr + InvalidOperationException thrown = (await act.Should().ThrowAsync()).Which; + thrown.Should().BeSameAs(expected); + } + + // ═══════════════════════════════════════════════════════════════ + // TESTS: ProcessOcrResultAsync - State Transition Failure + // Covers DocumentService.cs lines 148-151 (transitionResult.IsError branch) + // ═══════════════════════════════════════════════════════════════ + + [Fact] + public async Task ProcessOcrResultAsync_DocumentAlreadyCompleted_ReturnsCannotCompleteError() + { + // Arrange — document already in Completed state, OCR re-arrival + Document doc = new DocumentBuilder().AsCompleted().Build(); + + _repository.Setup(r => r.GetByIdAsync(doc.Id, It.IsAny())) + .ReturnsAsync(doc); + + DocumentService sut = CreateSut(); + + // Act + ErrorOr result = await sut.ProcessOcrResultAsync(doc.Id, "Completed", ExtractedOcrContent, + TestContext.Current.CancellationToken); + + // Assert — exact error code from DocumentErrors.CannotComplete + result.IsError.Should().BeTrue(); + result.FirstError.Type.Should().Be(ErrorType.Validation); + result.FirstError.Code.Should().Be("Document.CannotComplete"); + result.FirstError.Description.Should().Contain("Completed"); + } + + [Fact] + public async Task ProcessOcrResultAsync_TransitionFailure_LogsWarningAndDoesNotUpdateRepository() + { + // Arrange — document already in Failed state; MarkAsFailed should error + Document doc = new DocumentBuilder().AsFailed().Build(); + + _repository.Setup(r => r.GetByIdAsync(doc.Id, It.IsAny())) + .ReturnsAsync(doc); + + DocumentService sut = CreateSut(); + + // Act + ErrorOr result = await sut.ProcessOcrResultAsync(doc.Id, "Failed", null, + TestContext.Current.CancellationToken); + + // Assert + result.IsError.Should().BeTrue(); + result.FirstError.Code.Should().Be("Document.CannotFail"); + + _logCollector.GetSnapshot() + .Should().Contain(l => + l.Level == LogLevel.Warning && + l.Message.Contains("state transition failed", StringComparison.OrdinalIgnoreCase)); + + // Repository.UpdateAsync is intentionally NOT set up; MockBehavior.Strict will fail + // the test in Dispose if it were called.

The state machine d__5 moves from line-rate 88% / branch-rate 50% to line-rate 96% / branch-rate 100%. Adds one fact + one helper iterator to ListenerLifecycleTests.cs: GenAi_ExecuteAsync_TokenCancelledBetweenYields_BodyBreakCheckFires hits the `if (stoppingToken.IsCancellationRequested) { break; }` block inside the await-foreach. The pre-existing StoppingTokenCancelled test cannot reach it — cancellation through the [EnumeratorCancellation] token short-circuits the iterator before the loop body re-enters, so the body's IsCancellationRequested check never fires. The new YieldAfterCancel iterator deliberately ignores [EnumeratorCancellation], yields the second event after the test cancels the CTS, and forces the body-internal check to trip + break. Asserts: - DocumentService.UpdateDocumentSummaryAsync for event #2 → Times.Never - AckAsync → Times.Once - SseStream.Publish(e2) → Times.Never - "GenAI Result Listener stopped" Information log present (clean break, not throw) - No Error-level logs (proves it was a break, not a generic-catch rethrow) Remaining uncovered line: d__5 L34 (closing brace of `catch (OperationInterruptedException) when (...no queue...)`). That brace is the leave-instruction sequence point for a catch body whose last statement is `await Task.Delay(Timeout.Infinite, stoppingToken)`. Task.Delay with Infinite has no normal-return path — every reachable case throws OperationCanceledException out of the catch — so the leave target at L34 is unreachable Roslyn-emitted state-machine noise.
