test: assert from the AST that run() calls every hook BuildScript declares - #234
Conversation
The hooks are enumerated from the base's own declarations rather than named, so a third hook added beside the two that exist today is red until something calls it.

Assert the source path of HARNESS_ARTIFACT.
vm.getCode(string.concat(HARNESS_SOURCE, ":BuildScriptHarness")) validates code resolved from HARNESS_SOURCE, not the JSON read from HARNESS_ARTIFACT. A stale artifact that imports BASE_SOURCE can pass the current assertions.
Assert $.ast.absolutePath on harness before checking its base import.
Proposed fix
string memory harness = vm.readFile(HARNESS_ARTIFACT);
+assertEq(
+ vm.parseJsonString(harness, "$.ast.absolutePath"),
+ HARNESS_SOURCE,

Track executable calls, not all identifier references.
collectReferences records every Identifier.referencedDeclaration, so an uninvoked function value can mark a hook as reached. Collect declaration IDs only from FunctionCall callee nodes. Preserve the existing cutRelease() edge by explicitly recognizing its regenerateSnapshots callback passed to LibRainDeploySnapshot.freeze, which invokes that callback.
This localized change preserves the executable-reachability assertion without requiring a general call-graph model.

The sweep took the whole doc block off the three AST tests and off the walk helpers, along with the `@param`/`@return` tags. The tags are a restatement of the signature on an internal test helper and they stay cut; the rationale is not, and it is what these assertions mean: - why the wiring is read from the AST at all, when a harness can only show a hook that RAN; - why a hard-coded path needs the artifact-to-source chain, when a stale artifact of a renamed file passes a hook walk by holding no hooks; - why the hooks are enumerated from the base's declarations instead of named, what the call-set assertion cannot see, why order is not asserted here and where it is, and why a read-only hook is not `run()`'s to call; - why the import is matched by declaration id, why the top-level nodes are walked rather than indexed, why each predicate is the right test, and why the reference walk is generic over node shapes; - the termination argument for the fixpoint loop, which no line of it states. The three PROPERTY blocks the sweep left on the older tests in this same file are the style it removed from the new ones.

Direct ruling, not an issue: assert that
BuildScript.run()calls everyinternal virtualhookBuildScriptdeclares.What was wrong
src/abstract/BuildScript.soldeclares fourinternal virtualhooks and callsthem from its two entry points. Nothing asserted the wiring itself. Every
existing check was output-anchored —
BuildScriptTestdrives the harness andreads the markers the hooks wrote — so it sees a hook that is CALLED and says
nothing about one that is not. A hook added beside the two that exist today,
wired by nobody, leaves the whole suite green: a generator a deriving repo is
asked to implement and that no push ever runs, whose output drifts from its
inputs until a release cuts the drift into the append-only record.
Verified rather than assumed, on current
main: a third hook(
function regenerateDocs() internal virtual {}) added to the base and calledby nothing left the suite at 534 passed / 0 failed. A hook that only reads
(
function docRoot() internal view virtual returns (string memory)) left it at534 passed / 0 failed. A
recordRoot();added torun()— a statement of theentry point that regenerates nothing — left it at 534 passed / 0 failed. The
unmutated baseline is the same 534 passed / 0 failed.
What changed
test/src/abstract/BuildScript.t.solgains three assertions, read out ofsolc's AST of the base rather than from the source text, for the reason
GeneratedSnapshotShapeTestgives: this is about STRUCTURE, not formatting.Nothing under
src/orscript/changes.testRunCallsEveryHookThatRegenerates— the hooks are enumerated from thebase's own declarations (
internal+virtual), not named, and every one ofthem that can write (
stateMutabilityisnonpayable) must be called byrun(), which must hold nothing else. Naming today's two is the failurebeing fixed, so the walk finds a third hook the moment it is declared.
testEveryHookIsReachedFromAnEntryPoint— the other half, for the hooks thatonly read.
run()has no use forrecordRoot()orsnapshotContractNames(), so requiring it to call them would be wrong; ahook reached from NEITHER entry point is the same defect as an unwired
generator. Reachability rather than a direct call, because
regenerateSnapshotsreachesfreezeas an internal function pointer andnot as a call.
testTheAstIsTheBaseTheHarnessInherits— the no-subject guard. Both walksare claims about a file named by a hard-coded path, and an artifact left
behind by a moved source parses as well as a live one. The base is abstract
so its creation code cannot anchor it the way
CreditHyperCoreTestanchorsthe script; the chain runs through the concrete harness instead: the harness
artifact is the harness this suite compiles, the base it inherits was
imported from
src/abstract/BuildScript.sol, and the base artifact describesthat file.
Relation to #228
Disjoint, and complementary. #207 — the issue #228 closes — asks for the
arguments, the loop bound and the call ordering INSIDE the generator hooks;
this is the wiring TO them, which #207 does not ask for and #228 does not add.
#228 (
fix-207) opens a fixture-directory seam soregenerateLibscan be RUN,and pins the bytes it emits; it touches
script/Build.sol,test/concrete/BuildHarness.solandtest/script/Build.t.sol. This PR touches onlytest/src/abstract/BuildScript.t.soland asserts no bytes: #228 says one hook'sbody does the right thing when it is run, this says every hook the base declares
is run at all. Neither test would catch the other's mutation, and the two
branches share no file.
Migration
None. Test-only.
QA
testRunCallsEveryHookThatRegenerates,testEveryHookIsReachedFromAnEntryPoint,testTheAstIsTheBaseTheHarnessInherits- each fails on base in the only senseavailable to a test that does not exist there: the three mutations named above
were applied to
mainitself and the whole suite stayed green, and the samemutations on this branch are killed with the messages below.
src/abstract/BuildScript.solgainsfunction regenerateDocs() internal virtual {}, called by nothing (M1) ->testRunCallsEveryHookThatRegenerates(
run() does not call the hook regenerateDocs) ANDtestEveryHookIsReachedFromAnEntryPoint(nothing reaches the hook regenerateDocs)src/abstract/BuildScript.solgainsfunction docRoot() internal view virtual returns (string memory), called by nothing (M3) ->testEveryHookIsReachedFromAnEntryPoint(nothing reaches the hook docRoot)run()dropsregenerateLibs();(M2) ->testRunCallsEveryHookThatRegenerates(run() does not call the hook regenerateLibs). Also killed on base, by the existingtestRunRegeneratesAndFreezesNothingreading the marker that was neverwritten - this mutation is the half that was already covered.
run()gainsrecordRoot();(M4a) ->testRunCallsEveryHookThatRegenerates(run() holds a call that is not one of those hooks: 3 != 2)run()gainsvm.writeFile("mutation", "");- a regeneration inlined intothe entry point instead of reaching a hook (M4b) ->
testRunCallsEveryHookThatRegenerates(the entry point calls something other than a function of its own: MemberAccess != Identifier)BASE_ARTIFACTpoints at the harness's artifact instead of the base's (M5)->
testTheAstIsTheBaseTheHarnessInherits(the base artifact describes another file: test/concrete/BuildScriptHarness.sol != src/abstract/BuildScript.sol), and both walks withthe contract is not the base: BuildScriptHarness != BuildScriptstatements of its entry points. Independent of the implementation in the sense
that matters here: no name of any hook appears in the test, so the expected
set
cannot be edited to agree with a wrong
run()— it IS the declarations, andthe only way to satisfy it is to call them.
run()calls everyinternal virtualhookBuildScriptdeclares, enumerated from the AST ratherthan by naming today's two, red when a hook is added unwired. Covered:
enumerated by
visibility/virtualfrom the contract node; every hook thatwrites is required in
run(); the ones that only read are required to bereached from an entry point, which is where the literal reading of the ruling
does not hold and cannot —
run()calls neitherrecordRoot()norsnapshotContractNames()today, and requiring it to would be a false red oncorrect code. Both halves are red under an added hook (M1, M3).
