Add programmatic HTML reporting settings - #6699
Conversation
Resolve reporting switches lazily so values configured in before-test-discovery hooks apply after reporter registration. Environment variables retain higher precedence.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR adds programmatic controls for HTML and JSON reporting, but disabling JSON output can leave stale sidecar data in reused aggregation directories, which may later appear in merged reports. This is a bounded correctness risk that is mergeable with explicit owner awareness or follow-up. Sequence Diagram(s)sequenceDiagram

| Filename | Overview |
|---|---|
| src/TUnit.Core/Settings/ReportingSettings.cs | Introduces mutable, default-enabled settings for HTML generation, JSON sidecars, and artifact upload. |
| src/TUnit.Core/Settings/TUnitSettings.cs | Exposes reporting configuration through the public TUnit settings hierarchy. |
| src/TUnit.Engine/Reporters/Html/HtmlReporter.cs | Lazily resolves programmatic settings, resets session state, and coordinates sidecar publication and disabled cleanup. |
| src/TUnit.Engine/Reporters/Aggregation/ReportAggregator.cs | Adds bounded publication locking, pending-sidecar handling, and generation-scoped exclusion support. |
| src/TUnit.Engine/Reporters/Aggregation/ReportDataJson.cs | Adds publication generations and effective-sidecar selection shared by engine and standalone aggregation. |
| src/TUnit.Reporting.Tool/Program.cs | Updates standalone merging to honor pending, excluded, and actively published sidecars. |
| src/TUnit.Engine/Reporters/GitHubReporter.cs | Adds session-state reset and aggregate-summary cleanup needed by sequential and disabled-reporting flows. |

Code reviewReviewed the diff, No issues found. Checked for bugs and CLAUDE.md compliance. Notes from the review (no action needed):
Nice addition — this closes a real gap where the only way to control the HTML reporter was environment variables, which don't compose well with version-controlled project defaults. |

- Line 892: Update PublishArtifactAsync and its caller in
OnTestSessionFinishingAsync so SessionFileArtifact is published only when
IsArtifactUploadEnabled() is true, preserving the existing successful HTML-write
flow.
- Line 193: Gate the ReportAggregator.WriteSidecar(...) aggregation path with
IsJsonReportEnabled(), ensuring no aggregator creation, shared JSON sidecar
writing, or merged HTML regeneration occurs when JSON reporting is disabled via
either supported setting.
In `@tests/TUnit.UnitTests/TUnitSettingsTests.cs`:
- Around line 77-88: Update Reporting_Settings_Can_Be_Modified to execute in
both the default source-generation mode and reflection mode by adding the
appropriate reflection-mode test invocation, while preserving its existing
assertions and behavior.
Apply the same fix in
`@tests/TUnit.Engine.Tests/HtmlReporterConfigurationTests.cs` around lines 42 -
63: The reporter configuration tests require the same explicit execution-mode
and discovery-hook coverage.

reporter operations and the ConfigureReporting discovery hook using its

propagate the token parameter. Leave RunTestsWithFilter unchanged because its
available overload has no cancellation-token parameter.
