Suggested labels: Poem
Merge Risk: 🟡 Moderate · up to This documentation-only PR defines a future testing framework, but the current specification still leaves important implementation contracts incomplete or inconsistent around scheduling, fixture cleanup, interruption handling, call-count behavior, and integration details. Those gaps could lead to incompatible or incorrect implementations, so merge should wait for clarification or explicit owner acceptance. 🚥 Pre-merge checks | ✅ 20✅ Passed checks (20 passed)

The committed diff changes only documentation files; it adds no runtime API, tooling, build requirement, or completed implementation. The proposed architecture and decisions are recorded in the RFC and the companion UX and technical design documents, which define their scope and governing ADRs.

The technical design still introduces named invariants, and it explicitly recommends Full details: Testing (Compile-Time / Ui)Explanation Pass the check. The pull-request diff contains only five Markdown files: three design/RFC documents plus the documentation index and roadmap. It introduces no Rust, TypeScript, compiler, parser, serializer, renderer, or CLI implementation. The apparent public entities are Rust code examples inside the technical design, not declarations in the source tree. Therefore the compile-time test requirement does not apply.

Inline comments:
In `@docs/contents.md`:
- Around line 21-23: Shorten the link labels for the entries targeting
netsuke-test-framework-technical-design.md and
rfcs/0001-netsukefile-testing-framework.md to concise names such as “Technical
design” and “RFC 0001,” while retaining the full destination paths and keeping
the bullets within 80 columns.
In `@docs/netsuke-test-framework-technical-design.md`:
- Around line 108-126: Update the StdlibRegistration enum so both Full and Test
store Box<StdlibConfig>, matching the existing constructor in parse_with_config.
Update all Test constructors and pattern matches consistently while preserving
ManifestQuery unchanged.
- Around line 361-371: Update the Dispatch behavior for Spy calls so the
registry mutex is held only while appending the journal entry and selecting the
response or delegate, then release it before invoking the captured effective
implementation. Preserve existing Mock and Stub behavior, and add a test
covering a nested spy invocation that calls another double without deadlocking.
- Around line 391-394: Update the ArgMatcher enum to include an Exact(Value)
variant for eq and bare exact-equality syntax, then wire parser and
matcher-dispatch handling to construct and evaluate it. Add parser and dispatch
tests covering both forms while preserving existing matcher behavior.
- Around line 448-452: Update the technical design around ActionResult and
multi-action steps to define the results history schema, including its field,
ordering, and indexing, and specify how assertions access prior action results.
Ensure the evaluator contract explains stage comparisons consistently; otherwise
remove the stated multi-stage comparison capability.
- Around line 454-460: Update the scheduler design to specify report-sink
ownership: workers should send immutable case results through a channel to a
single collector, which restores sorted file and declaration order before
rendering. Add an interleaving test that completes cases out of order and
verifies stable human-readable and JSON output.
- Around line 517-519: Update the journal description in the matcher and
dispatch documentation to use an Oxford comma: separate “arguments” and
“responses” with a comma while preserving the surrounding wording.
- Around line 470-476: Update the Commands::Test dispatch contract and
implementation around testing::run to include interruption exit code 130
alongside 0/1/2/3. Preserve interruption as its dedicated exit result rather
than mapping it to an internal runner error, and add coverage for both Ctrl-C
handling and interrupted JSON output.
- Around line 541-544: Update the I8 report stream purity requirement to state
that --json always emits exactly one report document on stdout for both
successful and failed runs, while diagnostics are written to stderr.
- Around line 551-557: Update the I3 parameterized test plan to cover matcher
and consumption interactions, including an exhausted first match, ordered
fallback selection, and catch-all entries following specific matchers; do not
rely solely on helper-function separation as evidence of independence.
- Around line 373-377: Update the journal-entry design and DoubleRegistry
storage to use a stable journal identity, such as the double identifier plus
CallEntry index or a stable Arc/identifier, instead of a Rust reference to
CallEntry. Keep response-value deduplication independent from journal identity
and preserve the per-double journal ceiling behavior.
In `@docs/netsuke-test-framework-ux-design.md`:
- Around line 376-379: Clarify the contract for times: N across the UX and
technical designs: fewer than N calls must remain valid, exactly N must remain
valid, and calls beyond N must fail dispatch. Align end-of-case verification and
failure reporting with this maximum-call semantics, and update the
returns/raises behavior descriptions only where needed for consistency.
- Around line 877-878: Update the phrase “sub-case reporting” in the data-driven
case tables section to the closed compound “subcase reporting,” preserving the
surrounding text.
- Around line 706-714: Clarify the timeout contract for the per-case --timeout
option: either enforce the deadline across fixture actions, Ninja generation,
assertions, teardown, overlay dispatch, and loader callbacks, with tests
covering blocked fixture and teardown paths, or explicitly document enforcement
as best effort.
Apply the same fix in `@docs/netsuke-test-framework-technical-design.md` around
lines 462 - 466: The technical design repeats the same incomplete
timeout-boundary contract.
In `@docs/roadmap.md`:
- Around line 692-696: Update roadmap item 6.1.4’s dependency list to include
6.1.3, ensuring the dogfood and differential fidelity gate occurs only after the
macro-substitution seam is delivered.

Introduce the design set for a first-class `netsuke test` command and YAML test dialect: - `docs/netsuke-test-framework-ux-design.md` specifies the test tree, discovery, the `given`/`when`/`then` dialect, the stub/mock/spy double taxonomy with a closed matcher vocabulary and call journal, fixtures with guaranteed teardown, the command surface, and reporting with a FAIL/ERROR taxonomy. - `docs/netsuke-test-framework-technical-design.md` specifies the implementation architecture: a `Test` variant of the existing `StdlibRegistration` boundary, an options-carrying manifest loader entry point with template overlays registered before `foreach` expansion, a clock seam in `StdlibConfig`, sandboxed fixtures under `cap-std`, the mock engine, timeout and interrupt governance, and nine named verification invariants. - `docs/rfcs/0001-netsukefile-testing-framework.md` proposes the feature, positions it against roadmap phases 3 to 5, records the compatibility story for the manifest `tests` block, and evaluates four alternatives including a deterministic-override substrate that doubles as the first delivery phase. Ground the design in surveyed prior art (OpenTofu/Terraform test framework, OPA policy testing, Molecule, Terratest, Act; pymox, cmd-mox, shellmock, flexmock, Mockito) and revise it through a six-lens design review covering structure, alternatives, scaling, contracts, failure modes, and long-term viability. Build the seam design on the restricted-load pattern that `netsuke help targets` established rather than a parallel mechanism: extend `StdlibRegistration` with a `Test` mode, register impure helpers as refusing stubs following `register_manifest_query`, and reuse `disabled_env_reader` and the `manifest_query_operation_error` diagnostic shape. Expose target `description` on the graph assertion surface so tests can cover the new discovery metadata. Add roadmap phase 6 tracking delivery as numbered tasks, extend the canonical command vocabulary with `test`, and index all three documents from `contents.md`.
Address code review on the Netsukefile testing framework design set.
Findings were verified against the current implementation before being
actioned; those that no longer held were skipped.
Corrections where the design contradicted real behaviour:
- Macro substitution cannot work by `add_function` alone.
`register_macro` appends `{% from ... import <name> %}` to
`MACRO_IMPORTS_GLOBAL`, which `render_template` prepends on every
render, and a template-local import resolves ahead of an environment
global. The overlay must rewrite that prelude, and the phase-1 spike
now covers it.
- `workspace_root` does not scope `glob()` or the file tests:
`expand_glob` takes no root and `parent_dir` opens with ambient
authority. Require sandbox-rooted adapters for both under test,
leaving the build path's ADR-010 behaviour unchanged.
- `StdlibRegistration::Full` boxes its payload; box `Test` to match.
- Release the registry lock before invoking a spy's delegate, since a
spied callable may re-enter dispatch through another double.
- Identify journal entries by `(double, entry_index)` rather than a
borrowed `CallEntry`, which would be self-referential.
Contract gaps closed:
- Resolve the JSON stream-purity contradiction between the UX design,
invariant I8, and roadmap `5.5.2` on the run-completed axis: a
completed run always emits one stdout document, and only a command
failure empties stdout.
- Define `times: N` as a maximum rather than a quota, define the
`results` history schema, give the scheduler a single collector that
restores order, and add exit code 130 to the dispatch contract.
- Replace I3's structural-independence argument with four named
matcher and consumption interaction cases.
State the `--timeout` contract honestly rather than promising
enforcement the architecture cannot deliver: MiniJinja evaluation is not
preemptible, so the deadline is cooperative, its checkpoints are
enumerated, and a killable child process is named as the deferred fix.
Update the design set after rebasing onto eight upstream commits, so its code citations and assertion surface match the tree it describes. - Refresh two citations invalidated by module moves: `src/ast.rs` is now `src/ast/mod.rs:101`, and `src/ninja_gen.rs` is now `src/ninja_gen/mod.rs:87`. - Expose `dependency_order` on the graph target view. Serial dependency ordering reaches `BuildEdge`, so it is observable behaviour a test should assert on directly rather than by matching generated Ninja. - Record that the deferred `execute` action should drive `NinjaProcessOptions` rather than fabricating a `Cli`, since the runner's process layer was decoupled from the parser domain type for exactly that reason. Note: `docs/netsuke-design.md`, `docs/developers-guide.md`, `docs/formal-verification-methods-in-netsuke.md`, and roadmap task `3.14.3` still cite the pre-move `src/ninja_gen.rs` path. That drift predates this branch and is left for the change that moved the module.

Inline comments:
In `@docs/netsuke-test-framework-technical-design.md`:
- Around line 463-470: Update the fixture dependency-graph documentation around
src/testing/fixtures.rs to specify that independent fixtures are ordered
deterministically using declaration or request order as the topological-sort
tie-break, preserving the corresponding reverse teardown order. Add a test
covering independent fixtures and asserting their setup and teardown order.
- Around line 411-416: Clarify the ordered dispatch rules in the Dispatch
section for entries without a times limit: define how repeated calls consume or
revisit an unbounded entry, whether later entries can become reachable after it,
and whether matcher mismatches fall through to later entries or fail dispatch.
Add tests covering repeated calls, an unbounded entry followed by another entry,
and a mismatch, preserving the documented unlimited-match behavior.
In `@docs/netsuke-test-framework-ux-design.md`:
- Around line 820-881: Expand the worked-example section with a runnable Hello
World quick-start for new authors: include the command invocation, minimal
Netsukefile, minimal test file, and representative expected output from a
complete netsuke test run. Keep the existing C-project example intact and ensure
the quick-start demonstrates the documented CLI usage and test result structure
without requiring external tools or real filesystem dependencies.
- Around line 710-719: Expand the `--fail-fast` documentation to define
parallel-worker behavior: state whether in-flight cases finish or are cancelled,
mark unstarted cases as skipped, and specify the resulting human and JSON
summaries. Add a test covering more selected cases than `--jobs`, ensuring the
behavior preserves the technical design’s conservation and teardown guarantees.
- Around line 883-904: Add concise design-rationale sections beside the
non-goals and deferred-features list in docs/netsuke-test-framework-ux-design.md
at lines 883-904, covering risks and trade-offs, rejected alternatives, and
synchronisation with accepted decisions and implementation. Add the same
sections beside phasing and deferred work in
docs/netsuke-test-framework-technical-design.md at lines 709-732, following the
documents’ required structure and keeping the rationale consistent between both
designs.
- Around line 586-591: Constrain subject manifest resolution in the documented
precedence chain so action.manifest, given.subject, and case-level subject
reject absolute paths and paths escaping approved roots before
open_manifest_workspace loads them. Preserve the enclosing-project Netsukefile
as an explicit read-only exception, and add tests covering absolute paths and
traversal attempts.
In `@docs/roadmap.md`:
- Around line 787-793: Update roadmap task 6.6.1 to include task 6.4.2 in its
Requires list, preserving the existing prerequisites and task scope.
- Around line 711-715: Expand task 6.2.2 in the roadmap to include the test-file
netsuke_test_version contract, covering parser validation and tests for missing,
malformed, unsupported-major, and newer-minor values; accept only the supported
major version and minor-version range defined by RFC 0001.
- Around line 666-672: Add seam-specific tests for task 6.1.1 covering an
injected ClockProvider value, repeated now() calls, and the existing fallback
behavior when no provider is configured. Ensure the tests exercise registration
through StdlibConfig and verify the expected now() results without expanding the
implementation scope.

Constrain subject manifest paths before loading.
Reject action.manifest, given.subject, and case-level subject paths that are absolute or escape the approved roots. These fields are template-controlled, so this precedence chain can select an arbitrary host path. That conflicts with C2's sandbox guarantee, while src/manifest/query.rs Lines 49-82 accepts the supplied path through open_manifest_workspace. Preserve the documented enclosing-project Netsukefile case as an explicit read-only exception, then add absolute-path and traversal tests.

affected tests.
Implement subject-manifest path confinement for the `netsuke test` framework.
Requirements:
1. Define approved roots for subject manifests:
- the per-case sandbox, for fixture-created manifests; and
- the enclosing project `Netsukefile`, as an explicit read-only exception.
2. Before calling `open_manifest_workspace`, resolve and validate every
template-evaluated subject path from:
- an action-level `manifest` argument;
- `given.subject`; and
- case-level `subject`.
3. Reject absolute paths and paths that escape their approved root through
`..` traversal. Prevent symlink escapes if the implementation resolves
existing filesystem components.
4. Keep valid relative fixture paths working.
5. Add focused tests for each subject-path source that reject:
- an absolute path; and
- a traversal path such as `../../outside/Netsukefile`.
6. Add a test that permits the documented enclosing-project `Netsukefile`
exception without granting write access to the project root.
7. Update `docs/netsuke-test-framework-ux-design.md` and
`docs/netsuke-test-framework-technical-design.md` so their subject-path
rules match the implementation.

Replace the cooperative, best-effort `--timeout` contract with a hard per-case wall-clock bound, and resolve the review findings raised against the design set. Cooperative deadline checks cannot bound a runaway MiniJinja expression: evaluation is not preemptible, so one large loop in a target field runs indefinitely inside a single render, yielding to no checkpoint. Each case therefore executes in an independently killable child process. The parent keeps discovery, parsing, scheduling, deadline enforcement, child reaping, and report rendering; the child runs exactly one case and returns a `CaseResult`. The boundary reuses what already exists rather than inventing machinery: the `wait_timeout`-then-kill-then-reap pattern from `src/stdlib/command/execution.rs`, `Child::kill` for cross-platform termination, and length-prefixed `serde_json` frames versioned like `src/json_envelope.rs`. No new dependency is required. Cooperative checkpoints remain as the graceful path — a case that reaches one reports cleanly with a full journal and tears itself down — with termination as the backstop. Teardown ownership is assigned explicitly per outcome, timed-out sandboxes are retained, and invariant I10 states the test obligations, including a deliberately non-cooperative template expression and deterministic clock-injected fixture setup and teardown expiry. Also address the accompanying review findings: - Align end-of-case verification with the normative `times: N` maximum-call contract; only a zero-match `Mock` entry is unmet. - Define ordered-dispatch rules for entries without a `times` limit, and mismatch behaviour under both ordering modes. - Break topological-sort ties deterministically so independent fixtures set up and tear down in a stable order. - Add a Hello World quick start, `--fail-fast` behaviour under parallelism, risks and trade-offs, rejected alternatives, and a synchronization section. - Add roadmap coverage for the clock seam's tests, the `netsuke_test_version` contract, and the sandbox-rooted `glob()` and file-test adapters. Skipped one finding: constraining subject-manifest paths against absolute and traversing forms. The subject manifest is loaded through the same ambient-authority path `netsuke build -f <path>` already uses for user-supplied paths, and is deliberately not a sandboxed artefact the way fixture-written files are. Sandboxing it would be a new restriction on existing behaviour, not a gap in this design.

The sentence introducing the selection rules claimed ordering "changes which entries are eligible, not what happens on a mismatch", but the paragraph immediately below it states the opposite: an ordered double fails dispatch on a mismatch, whereas an unordered one falls through to later entries. Ordering governs both, so say so. Found while re-verifying the `times: N` maximum-call contract against both design documents. That contract needed no change: end-of-case verification already treats `times` as a maximum, fails only a `Mock` entry that matched zero calls, and never reports an unspent budget as unmet. A sweep of both documents for `times`, `unmet`, `expectation`, `verification`, and `remaining budget` found no remaining contradiction.

Define the fixture tie-break over ready nodes.
The text says that requested fixtures come first and uses dependencies follow. A literal implementation can violate dependency precedence for a fixture such as A uses C. Define the tie-break only among fixtures with no unmet dependencies: prefer requested fixtures by request order, then use declaration order for other ready fixtures. Preserve reverse teardown from the resulting setup order.

Summary
This branch specifies a first-class testing framework for Netsukefiles: a
netsuke testcommand, a YAML test dialect withgiven/when/thensteps,declarative mocking at named seams, and hermetic fixtures. It adds
documentation only; no runtime behaviour changes.
The motivation is a verification gap. Netsukefiles carry real logic —
foreachexpansion,whenconditions, macros, environment probes, globbing,and
command_availablebranches — and today the only way to check that logicis to run a build and inspect the result by hand. Negative properties cannot
be checked at all, environment-dependent behaviour cannot be pinned, and
refactoring a non-trivial manifest is unprotected.
The branch carries pre-implementation design. It authorizes the delivery work
now tracked as roadmap phase 6; no implementation is included, and the RFC
remains in
Proposedstatus pending review.This branch introduces
docs/rfcs/, so RFC 0001 is the repository's firstRFC and establishes the directory the documentation style guide already
specifies. No issue or existing roadmap task governs the work; the branch
creates the roadmap phase rather than implementing one.
Review walkthrough
docs/rfcs/0001-netsukefile-testing-framework.md
for the proposal in isolation: the problem, the current pipeline
constraints, the compatibility story for the manifest
testsblock, andfour alternatives. Option C (deterministic overrides with external
assertions) is a deliberate steelman that also doubles as the first
delivery phase, so reviewers unconvinced by the dialect have a documented
exit.
docs/netsuke-test-framework-ux-design.md
for the authored surface. The load-bearing sections are the mocking model
at
§8
(stub/mock/spy doubles, first-match-wins call entries, a closed matcher
vocabulary, and a bounded journal) and the assertion semantics at
§11,
which separate assertion failures from evaluation errors and require
negative tests to name the diagnostic they expect. The worked example at
§14
is the clearest single statement of what the framework buys.
docs/netsuke-test-framework-technical-design.md
for the architecture, and read
§3.2
first. It records the most consequential decision in the document: the
test runner is a third mode of the restricted-load pattern that
netsuke help targetsalready established, so it extendsStdlibRegistrationwitha
Testvariant instead of introducing a parallel boundary mechanism. Theordering constraint in
§3.1
is the other critical fact: overlays must register after the standard
library and manifest macros but before
foreachexpansion, becauseforeachandwhenevaluate against the raw value tree ahead of typeddeserialization.
§4
record why the clock needs a new seam, why the network needs none, and
what the sandbox-rooted standard-library configuration implies for
visibility.
§11
as the acceptance contract: nine named invariants, each with a
verification method and a stated scope boundary, including case isolation,
teardown ordering, semantic fidelity, build-path neutrality, and
conservation of cases under panic or interruption.
docs/roadmap.md
for phase 6 and
docs/contents.md
for the index entries. Phase 6 sequences the seam work and the overlay
spike first, and
task 6.1.4
gates dialect work on dogfooding the seams against the repository's own
example manifests. The roadmap's canonical vocabulary list gains
testatline 69.
Validation
make markdownlint: pass (Summary: 0 error(s)across 85 files; includesthe
typosen-GB-oxendict gate).make nixie: pass (All diagrams validated successfully!; the sole newdiagram is the case-execution flow in the technical design).
make check-fmt,make lint,make test: run after the rebase to confirmthe rebased tree is sound. The branch touches no Rust, so these gates
verify the base rather than the change.
Notes
The design is grounded in a survey of the prior art requested during
drafting. It adopts OpenTofu and Terraform's plan-mode-by-default split,
Open Policy Agent's FAIL/ERROR taxonomy and substituted-value failure output,
shellmock's first-match configuration lists and suggested-stanza errors, the
flexmock and cmd-mox stub/mock/spy taxonomy, and Mockito's unnecessary-stub
insight. Act's published fidelity gaps motivated the commitment that the test
runner and the build share one compiler rather than emulating it.
A six-lens design review covering structure, alternatives, scaling,
contracts, failure modes, and long-term viability drove substantive
revisions before this branch was committed. The most consequential:
semantics would have re-run the loader per action, double-counting mock
calls and breaking
timesbudgets.configuration, which legitimately changes what a manifest observes under
test.
MAJOR.MINORacceptance policy, aneq:matcher as a literal escape hatch, and normative equality rules.
fetchis a suite error,because the deny-all network policy leaves nothing to pass through to.
new invariant requiring every selected case to reach the report exactly
once.
The branch was then rebased onto
mainafternetsuke help targetslanded,and the design was updated to build on what that work introduced rather than
around it: the
Testmode extendsStdlibRegistration, impure helpers areregistered as refusing stubs following
register_manifest_queryinstead ofbeing left unregistered for MiniJinja's generic unknown-function error, and
disabled_env_readerbecomes the base of the per-case environment reader.Target
description— new user-authored discovery metadata — is exposed onthe graph assertion surface so tests can cover it, with the distinction from
a rule's Ninja progress description stated explicitly. All code citations in
the technical design were re-verified against the rebased tree, including the
move of
src/ast.rstosrc/ast/mod.rs.Two items are deliberately left open and flagged in the documents. Macro
substitution depends on MiniJinja
add_functionshadowing semantics that aredocumented upstream but unproven in this codebase; roadmap task 6.1.3 is the
spike that settles it, with a stated fallback. Diagnostic-code matching in
expect_failureships only once the in-flight diagnostics migration settlesand the code namespace can be declared stable.
