possible, a specific normative statement +- **Readability**: the tests should read close to the spec and close to GraphQL examples, not like framework plumbing +- **Normative fidelity**: assertions should reflect required observable behavior, not inferred internal implementation details +- **Gap visibility**: missing coverage, skipped cases, spec ambiguities, and implementation gaps must be explicit +- **Determinism**: failures and ordering should be stable and easy to compare over time +- **Reviewability**: diffs should be small, obvious, and clearly tied to spec behavior +- **Versioned conformance**: the suite must make clear which spec draft and reference cases it aligns with +- **Implementation independence**: tests should verify externally visible GraphQL behavior, not GraphZen internals + +## Project Intent + +This project should become the canonical home for spec conformance coverage. + +- Reusing existing test classes from other test projects is acceptable as an

Rename or split the tests until the mapping is unambiguous. + +### Transitional Multi-Section Classes + +Some current wrapper classes still represent more than one subsection by carrying multiple `SpecSection` attributes. Treat that as temporary migration structure, not the desired steady state. + +- acceptable short term: one wrapper class with multiple `SpecSection` attributes while coverage is being lifted into this

mixed coverage + +Adjacent documentation or coverage manifests should follow the same exact subsection identity as the class they describe. + +If those four representations disagree, fix the structure rather than relying on comments to explain it. + +## Readability Standards + +Conformance tests should read like executable spec text. + +- Name classes and methods in language that matches the spec, not local implementation jargon +- Keep GraphQL documents formatted as real GraphQL, not compressed string blobs +- Prefer short, section-local helpers over deep abstraction stacks +- Avoid helpers that hide the actual GraphQL input or expected outcome +- Repeat simple setup if it makes the rule easier to understand +- Comments should explain intent only when the spec nuance is not obvious from the test itself + +The reader should usually understand the rule and expected behavior without opening product code. + +Where practical, a reviewer should also be able to line up: + +- the subsection heading in the spec website +- the conformance class name +- the individual method names + +without translation. + +## Test Design Rules + +Prefer tests with a single clear responsibility. + +- A positive test should usually prove one thing is allowed +- A negative test should usually prove one thing is rejected +- Avoid broad "kitchen sink" tests unless the spec itself is testing composition +- Separate positive, negative, edge-case, and not-applicable coverage clearly +- Assert observable GraphQL behavior only: results, errors, nullability, ordering guarantees if required, and schema

+1,84 @@ # AGENTS.md -This directory contains GraphZen's specification conformance suite -- an executable conformance statement that makes it easy to answer what part of the GraphQL spec is represented, enforced, a known gap, or not applicable. +GraphZen's specification conformance suite -- an executable conformance statement mapping the GraphQL spec to test coverage. Each class maps to one spec subsection, each method proves one normative statement, and gaps are always explicit. The directory should read like an executable appendix to the GraphQL spec. -## Current State +## Coverage Principles -- Only **Chapter 5 (Validation)** has conformance structure. No other chapters have classes or manifest entries yet. -- **29 validation subsections** are listed in `SpecCoverageManifest.ValidationSections`. -- All conformance classes are **native conformance classes** extending `SpecValidationRuleHarness` with inline GraphQL and TheoryData. -- **All negative validation tests are currently skipped** -- the validation rule implementations do not yet reject invalid queries. Positive tests pass. -- The project depends on `GraphZen.Tests` for `ValidationRuleHarness` and its shared `TestSchema`. -- Spec draft version is centralized in `Infrastructure/SpecMetadata.cs`. +The spec is the sole source of truth for what this suite covers. graphql-js is a supplement for example test cases, not a coverage guide. + +- **Every spec test case gets written** with its query and expected outcome, regardless of whether GraphZen can pass it today. The test body should contain the actual GraphQL query and assertion call. +- **Skip the test, not the work.** When GraphZen lacks an implementation, the test is skipped with a reason pointing at the implementation gap. The skip message describes what GraphZen needs to implement, not that the test is deferred. +- **Empty placeholders are temporary.** A skipped `[Fact]` with an empty body is acceptable only while actively porting test cases. The goal state is a fully-written test that's skipped because the implementation isn't there yet — not a placeholder that says "we'll write this later." +- **The manifest is driven by the spec**, not by GraphZen's capabilities. Every validation subsection in the spec gets a manifest entry. +- **The suite is agnostic of GraphZen internals.** Conformance classes should not reference GraphZen implementation details. The harness provides `ExpectValid`, `ExpectErrors`, and `ToDeepEqual` — that is the full API surface for test authors. ## Running Tests ```sh -# all conformance tests -dotnet test --project test/GraphZen.SpecConformance.Tests/ - -# all Chapter 5 tests -dotnet test --project test/GraphZen.SpecConformance.Tests/ --filter "SpecSection=5" - -# all Fields subsection tests (5.3.x) -dotnet test --project test/GraphZen.SpecConformance.Tests/ --filter "SpecSection=5.3" - -# one exact subsection -dotnet test --project test/GraphZen.SpecConformance.Tests/ --filter "SpecSection=5.3.3" +dotnet test --project test/GraphZen.SpecConformance.Tests/ # all conformance tests +dotnet test --project test/GraphZen.SpecConformance.Tests/ --filter "SpecSection=5" # Chapter 5 +dotnet test --project test/GraphZen.SpecConformance.Tests/ --filter "SpecSection=5.3" # Fields (5.3.x) +dotnet test --project test/GraphZen.SpecConformance.Tests/ --filter "SpecSection=5.3.3" # one subsection ``` Hierarchical filtering works because `SpecSectionDiscoverer` expands `"5.3.3"` into traits for `"5"`, `"5.3"`, and `"5.3.3"`. -## Adding a Conformance Class (Step by Step) - -This is the most common task.
