From cd95c9f6595d7c0ef91deed9dd9d5251e48075d3 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 3 Feb 2026 18:46:01 +0000 Subject: [PATCH 01/10] Wire testgen-check into make test, update testgen TODO with current state Add MetaTarget.additional_deps field to support extra prerequisites beyond prep_level. The test target now depends on testgen-check, so `make test` fails early if generated tests are stale rather than running against outdated test code. Update testgen-improvements.md: check off 9 of 11 TODOs that are already implemented (MockSpec enforcement, NodeExample types, per-node test generation, Makefile targets, staleness check). Resolve open questions (commit with staleness checks, builder pattern syntax). Document remaining work: auto-discover DAGs (TODO 1.3) and adding node_examples to existing MockSpecs. https://claude.ai/code/session_01FcPT2VEZdE1W7QdL7SjJgC --- TODO/testgen-improvements.md | 66 +++++++++++++++++++------------ gunbc-dag/src/makegen/registry.rs | 2 +- gunbc-dag/src/makegen/render.rs | 22 ++++++++--- 3 files changed, 57 insertions(+), 33 deletions(-) diff --git a/TODO/testgen-improvements.md b/TODO/testgen-improvements.md index d7d1235f732..843da849671 100644 --- a/TODO/testgen-improvements.md +++ b/TODO/testgen-improvements.md @@ -1,7 +1,8 @@ # Testgen Improvements -**Status**: TODO +**Status**: In Progress **Date**: 2026-02-02 +**Updated**: 2026-02-03 ## Problem Statement @@ -24,23 +25,29 @@ When you define a DAG node, you also specify its I/O contract.

They're not blocking — tests compile +and run — but they reduce confidence in what's actually being verified. + +--- + +## 1. Satisfies matcher emits a comment, not an assertion + +**Where**: `core/test/src/mock_spec.rs` `OutputMatcher::Satisfies` arm of +`to_check_code()` + +**What happens**: `Satisfies` carries a `predicate: fn(&Value) -> bool` +closure, but closures can't be serialized to Rust source. So `to_check_code()` +emits: + +```rust +// Custom assertion: skip is a boolean +``` + +The generated test binds the output variable and checks it exists (via +`.expect()`), but **never asserts anything about the value**. There are +~8 CI node examples and ~2 makegen examples using `Satisfies` today. +They provide false confidence — they look like they test something, but +the actual predicate is never evaluated. + +**Why it matters**: Someone reading the generated test sees `output_skip` +is bound and assumes it's checked. It isn't. If the node starts returning +the wrong type, nothing catches it. + +**Root cause**: Codegen operates at the source-text level. It can't +embed a closure reference into generated Rust code without some form of +indirection. + +**Possible approaches**: + +1. **Runtime callback**: Instead of inlining the predicate, emit code + that calls back into the MockSpec at test time: + ```rust + let spec = ci_mock_spec(); + spec.node_examples[3].outputs["skip"].check(output_skip); + ``` + This requires `OutputMatcher::check(&self, &Value) -> Result<(), String>` + (which already exists as `OutputMatcher::matches()`) and generating + the index/lookup code. Downside: generated tests depend on MockSpec + construction being deterministic and index-stable. + +2. **First-class matcher variants**: The common patterns (`is_bool`, + `is_non_negative_int`, `matches_type`) could be `OutputMatcher` + variants with known codegen. `Satisfies` would remain as an escape + hatch for truly custom predicates, but most uses would migrate to + the typed variants: + ```rust + OutputMatcher::IsType(ValueType::Bool) + OutputMatcher::IntRange { min: 0, max: None } + ``` + These can be serialized to `assert!(matches!(output, Value::Bool(_)))`. + +3. **Hybrid**: Emit a `todo!("custom assertion: ...")` so the test + explicitly fails/panics rather than silently passing. Forces the + author to either use a serializable matcher or acknowledge the gap. + +**Affected files**: +- `ci/graph_mock.rs` — `prepare_codegen_cmd`, `prepare_build`, + `prepare_test`, `parse_clippy_lint` (2 outputs each) +- `makegen/graph_mock.rs` — `load_registry` `tool_count` + +--- + +## 2. Parse nodes tested via Value::Skipped only verify skip propagation + +**Where**: `bootstrap/graph_mock.rs` (`parse_scan_result`), +`ci/graph_mock.rs` (`parse_deps_exists`, `parse_codegen_exists`), +`lib/llm-ops/src/graph_mock.rs` (all 4 `parse` examples) + +**What happens**: These node examples provide `input("response", +Value::Skipped)` and check `OutputMatcher::Any`. The node's skip-handling +path runs (`if matches!(input, Value::Skipped) { return all-Skipped }`), +but the **actual parsing logic is never exercised** at the integration +test level. + +The parsing logic IS tested in unit tests in `ops.rs` for each tool. +So this isn't untested code — it's untested *at the generated-test layer*. + +**Why it matters**: The whole point of node examples is to verify nodes +work in DAG context with realistic I/O. Testing only the skip path +doesn't do that. + +**Root cause**: `value_to_rust_literal()` can't serialize +`Value::Response(TransportResponse::Shell(ShellResponse { ... }))` to +Rust source. The catch-all arm maps unknown variants to +`Value::Str("")` (see hack #4). So there's no way to provide a +realistic transport response as an example input in generated code. + +**Possible approaches**: + +1. **Extend `value_to_rust_literal()`** to handle `Value::Response` and + `Value::Request` — emit the full constructor chain: + ```rust + Value::Response(gunbc_ir::transport::TransportResponse::Shell( + gunbc_ir::transport::ShellResponse { + exit_code: 0, + stdout: "crates/foo\ncrates/bar\n".to_string(), + stderr: String::new(), + } + )) + ``` + This is verbose but mechanical. Each `TransportResponse` variant + (Shell, File, Rest) needs a serializer. Once this works, examples + can provide real responses and assert real parse outputs. + +2. **Mock response builder in codegen preamble**: Emit helper functions + at the top of the generated test module that build mock responses, + then reference them by name in examples. This keeps the test body + readable. + +**Affected nodes** (7 total): +- `bootstrap::parse_scan_result` +- `ci::parse_deps_exists`, `ci::parse_codegen_exists` +- `llm::parse` (openai, anthropic, code_review, secrets) + +--- + +## 3. NonEmpty matcher vacuously passes on non-string Values + +**Where**: `core/test/src/mock_spec.rs` `OutputMatcher::NonEmpty` arm of +`to_check_code()` + +**What happens**: Generated code is: + +```rust +assert!(!output_request.as_str().map(|s| s.is_empty()).unwrap_or(false), "expected non-empty"); +``` + +`as_str()` returns `None` for `Value::Request(...)`, `Value::Int(...)`, +`Value::Bool(...)`, etc. When it returns `None`, `.unwrap_or(false)` makes +the inner expression `false`, then `!false` is `true`, and the assertion +passes.

If someone writes: + +```rust +NodeExample::new("my_node") + .input("request", Value::Request(TransportRequest::Shell(cmd))) +``` + +The generated test would pass `Value::Str("")` as input. The node +would fail with a confusing "missing request" error, not a clear +"unsupported Value variant in codegen" error. + +**Why it matters**: This is a silent data corruption path.

From e11a501955fa287d2f9fc4f6013928f7a2ab0b47 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 3 Feb 2026 20:13:33 +0000 Subject: [PATCH 04/10] Fix clippy warnings in generated node example tests Three codegen fixes: - Collapse runs of underscores in test name sanitization (non-snake-case) - Omit `mut` on inputs HashMap when no inputs are inserted (unused-mut) - Prefix output variables with `_` when matcher emits only a comment, i.e. Satisfies and Any variants (unused-variables) Added OutputMatcher::generates_assertion() to distinguish matchers that emit executable assertions from those that emit comments. https://claude.ai/code/session_01FcPT2VEZdE1W7QdL7SjJgC --- core/codegen/src/testgen/codegen.rs | 62 ++++++++++++++----- core/test/src/mock_spec.rs | 7 +++ gunbc-dag/src/bootstrap/generated_tests.rs | 14 ++--- gunbc-dag/src/ci/generated_tests.rs | 40 ++++++------ gunbc-dag/src/makegen/generated_tests.rs | 8 +-- lib/llm-ops/src/generated_tests.rs | 6 +- lib/llm-ops/src/generated_tests_anthropic.rs | 6 +- .../src/generated_tests_code_review.rs | 6 +- lib/llm-ops/src/generated_tests_secrets.rs | 6 +- 9 files changed, 97 insertions(+), 58 deletions(-) diff --git a/core/codegen/src/testgen/codegen.rs b/core/codegen/src/testgen/codegen.rs index 20583080acf..4646249f4d6 100644 --- a/core/codegen/src/testgen/codegen.rs +++ b/core/codegen/src/testgen/codegen.rs @@ -1675,11 +1675,7 @@ impl<'a, T> TestGenerator<'a, T> { // 1.

Test Pattern Retrospective + +**885 manually written tests surveyed** across the codebase. +All are purely in-memory — zero real I/O in any test today. + +### Pattern 1: Function Unit Tests (HashMap → execute → assert) + +The most common pattern. Build a `HashMap` of inputs, +call the op's `execute()`, assert specific output ports. + +**Where**: `gunbc-dag/src/ci/ops.rs`, `gunbc-dag/src/bootstrap/ops.rs`, +`lib/llm-ops/src/ops.rs`, every `ops.rs` file. + +```rust +let mut inputs = HashMap::new(); +inputs.insert("response".into(), Value::Str(json_string)); +let outputs = op.execute(&inputs)?; +assert_eq!(outputs.get("build_success"), Some(&Value::Bool(true))); +``` + +**Consolidation opportunity**: This is exactly what `NodeExample` now +automates via testgen. Once Tier 1 infra (`execute_single_node`) +is stable, many of these hand-written tests become redundant with +their generated equivalents. Keep hand-written tests only for +edge cases not expressible as `NodeExample`. + +### Pattern 2: Graph Structure Tests (static DAG properties) + +Tests that verify node counts, boundary lists, entrypoints, +transport ports, and edge connectivity — without executing the DAG. + +**Where**: `gunbc-dag/src/ci/graph.rs`, `gunbc-dag/src/makegen/graph.rs`, +`lib/tools/gist/src/graph.rs`. + +```rust +let dag = build_ci_graph()?; +assert_eq!(dag.nodes.len(), 15); +assert!(dag.has_node("prepare_build")); +let boundaries = detect_boundaries(&dag); +assert!(boundaries.transport_nodes.contains(&"execute_transport")); +``` + +**Consolidation opportunity**: Testgen's Bucket A already covers +boundary detection and transport interception. Remaining structural +tests (node counts, specific node existence) are fragile — they +break whenever the graph changes. Consider replacing with +property-based checks (e.g., "all pure nodes have examples") +rather than hard-coded counts. + +### Pattern 3: Signature Validation (validate + infer) + +Tests that verify type signature consistency at the port level: +validate a node's signature, then infer types from connected edges. + +**Where**: `gunbc-dag/src/makegen/graph.rs`, `core/ir/src/dag.rs`. + +```rust +let sig = node.signature(); +assert!(sig.validate().is_ok()); +let inferred = sig.infer_from(&connected_edges); +assert!(inferred.is_compatible_with(&sig)); +``` + +**Consolidation opportunity**: Testgen proves type compatibility by +construction (see header comment in generated files). These tests +are mostly redundant once testgen covers the DAG. Keep only for +testing the signature validation API itself (in `core/ir`). + +### Pattern 4: Mode-Based Testing (enum variant parameterization) + +Tests that exercise different modes/configurations of the same graph, +verifying structural differences. + +**Where**: `lib/tools/gist/src/graph.rs` (Snapshot vs Diff mode). + +```rust +let snapshot_dag = build_gist_graph(GistMode::Snapshot)?; +let diff_dag = build_gist_graph(GistMode::Diff)?; +assert!(diff_dag.has_node("git_diff")); +assert!(!snapshot_dag.has_node("git_diff")); +``` + +**Consolidation opportunity**: Testgen currently generates one test +suite per MockSpec/DAG pair. Mode-parameterized DAGs need one +MockSpec per mode. This is already handled (gist has separate +MockSpecs) but could be formalized as a pattern in the testgen +framework. + +### Pattern 5: Execution Mode Testing (DryRun with BoundaryMocks) + +Integration-style tests that execute the full DAG in DryRun mode +with mocked transport responses, verifying execution flow. + +**Where**: `lib/tools/gist/tests/integration.rs`, +`lib/tools/buck2/tests/integration.rs`. + +```rust +let dag = build_gist_graph(GistMode::Snapshot)?; +let mocks = gist_mock_spec().to_boundary_mocks(); +let log = execute_with_mode(&dag, ExecutionMode::DryRun(mocks))?; +assert!(log.get("create_gist").unwrap().was_intercepted); +``` + +**Consolidation opportunity**: This is exactly testgen Bucket A + C. +These hand-written integration tests are now fully subsumed by +generated tests. Once testgen covers all DAGs, these files can be +deleted or reduced to edge-case-only suites. + +--- + +## 6. Integration Test Gap Analysis + +**Current state**: All 885 tests are in-memory.

Testgen and codegen look up these strings +to generate code. If a builder function is renamed, no compile +error is produced — it fails at runtime or generates wrong code. + +**Fix**: Store an enum key (e.g., `GraphBuilderId`) instead of a +string. Map enum → function in one place. Renames then produce +compile errors. + +### `buck-out/gen` hardcoded in 16 locations + +**Where**: 5 source files across `core/codegen/src/main.rs`, +`gunbc-dag/src/makegen/render.rs`, `gunbc-dag/src/ci/ops.rs`, +`gunbc-dag/src/bin/ci.rs`, `gunbc-dag/src/ci/graph_mock.rs`. + +The output directory path is scattered as string literals.

Ports reference type contracts, not raw `type_id` strings + +**Current**: Ports store `type_id: String` (e.g., `"String"`, `"Bool"`, +`"Json"`). Type compatibility is checked by string equality. + +**Goal**: Ports reference a `TypeContract` (or type DAG) that carries +base type + cardinality + predicates as structured data. + +`TypeContract::from_type_dag` already exists (`core/ir/src/contract.rs`) +and extracts cardinality, base type, predicates, and wrapper kind from +a type DAG.

Most current uses are `is_bool`, `is_non_negative_int`, +`matches_type` patterns — these map directly to `IsType` and `IntRange`. + +--- + +## 4. Tape order semantics + +**Current**: `Value::List` uses derived `PartialEq`, which is +order-sensitive. `vec![a, b] != vec![b, a]`. + +**Question**: If "tape = set/bag" is a design goal, should list equality +be order-insensitive? This affects: +- `OutputMatcher::Exact` on list values +- Edge compatibility (does `[a, b]` satisfy a port expecting `[b, a]`?) +- Testgen: generated assertions with `assert_eq!` on lists + +**Options**: +1. **Lists are ordered** — current behavior. Simple, predictable. + "Tape" is a metaphor for sequential processing, not set membership. +2. **Lists are unordered (set/bag)** — add canonicalization (sort) + before equality checks.
