| Rooting `workspace_root` at the sandbox has a visibility consequence worth | ||

There was a problem hiding this comment.
Rooting StdlibConfig at the sandbox does not currently scope either helper named here: src/manifest/mod.rs registers glob() via ambient glob::expand_glob, while register_file_tests ultimately opens each supplied path with ambient authority. Consequently, an unmocked relative glob or file test—especially in the documented fixture workflow—observes the runner's working directory rather than the per-case files and can produce host-dependent results. The design needs explicit sandbox-rooted adapters for both helpers rather than relying on workspace_root.

There was a problem hiding this comment.
Registering a same-named function last does not substitute a manifest macro in rendered target fields. render_template in src/manifest/jinja_macros/mod.rs prepends a {% from ... import <macro> %} statement on every render, and that imported template-local macro shadows the global function installed by add_function. Thus the documented compile_cmd: substitute(...) example still invokes the original macro during command rendering and records no substitution call; the overlay mechanism must filter or replace the generated macro import, not merely replace the global registration.

There was a problem hiding this comment.
Checking the deadline only during overlay dispatch and stage callbacks cannot enforce the promised wall-clock timeout. For example, a target field containing a very large MiniJinja loop can spend indefinitely in final rendering after the FinalRendering stage callback, without invoking any overlay or entering foreach, so the worker never reports the case as errored and netsuke test can hang beyond --timeout. The case needs an isolation or cancellation boundary that can stop non-cooperative template evaluation.

There was a problem hiding this comment.
For any failing test run, this requires a report document on stdout plus diagnostics on stderr, but the newly referenced roadmap contract at docs/roadmap.md:631-636 requires failing JSON mode to leave stdout empty and emit exactly one stderr document; technical invariant I8 likewise says failure emits on stderr only. An implementation cannot satisfy both the UX specification and its required stream-purity behavioural test, so the documents must distinguish test-result failures from command errors or choose one stream contract.

The normative UX requires bare arguments and eq: <value> to perform structural exact matching, but the technical design's closed ArgMatcher enum contains no exact/equality variant. Following this AST leaves no representation for the most common declaration, including args: ["src/*.c"] in the worked example, nor for the documented escape hatch used to match one-key mappings that resemble matchers. Add an Exact(Value)/Eq(Value) variant and its parsing rule.

| `netsuke help targets` established the pattern this framework extends. The | ||
| loader already selects its standard-library boundary through an enum | ||
| (`StdlibRegistration`, `src/manifest/mod.rs:113`) with two variants: | ||
| `Full(StdlibConfig)` for builds, and `ManifestQuery` for side-effect-free | ||
| discovery. `src/manifest/query.rs` owns that boundary, and | ||
| `register_manifest_query` (`src/stdlib/register.rs:114`) implements it by | ||
| registering the pure helpers and replacing `env`, `glob`, `fetch`, `shell`, | ||
| `grep`, and `contents` with stubs that raise a located diagnostic naming | ||
| the unavailable operation. | ||
|
|
||
| The test runner is a third load mode of exactly this shape, so it extends | ||
| the existing enum rather than introducing a parallel mechanism: | ||

| Dispatch: the overlay closure for a double locks the registry, appends the | ||

| unconsumed entry in declaration order), and returns the entry's response. | ||
| A `Mock` with no accepting entry returns a MiniJinja error carrying a | ||
| structured payload; the runner converts it into the unmatched-call report | ||
| with the suggested YAML stanza. A `Stub` falls back to its `default` or | ||
| `Undefined`. A `Spy` delegates to a handle the runner captured when it | ||

| rather than retrieving previously registered functions from the MiniJinja | ||

Release the registry lock before invoking a spy.
The registry is behind Arc<Mutex<..>>. The dispatch description locks the registry and then delegates a Spy call to an effective implementation. If that implementation invokes another double, the same thread re-enters the mutex and deadlocks.
Lock only for journal updates and response selection. Release the lock before invoking the delegate. Add a nested-spy test.

Define a stable journal identity instead of a CallEntry reference.
The design stores CallEntry values inside DoubleRegistry and describes journal entries as references to them. Do not implement this as &CallEntry; the self-referential layout cannot be represented safely with ordinary Rust references.
Store the double identifier and entry index, or use a stable Arc or identifier. Keep response deduplication separate from journal identity.

Define timeout enforcement consistently across both designs.
The UX design promises a per-case wall-clock budget, while the technical design checks the deadline only during overlay dispatch and loader callbacks. Fixture actions, Ninja generation, assertion evaluation, and teardown can therefore exceed the documented budget. State whether enforcement is best effort or instrument every required boundary, and add coverage for blocked fixture and teardown paths.

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.

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.
