Summary by Sourcery

Tighten test failure behavior by making test setup operations panic on failure, while simplifying test signatures and aligning lint configuration to permit explicit panics and expects in tests.

Enhancements:

  • Relax clippy configuration to allow expect and panic usage within tests, and remove now-unnecessary clippy expect annotations from test modules.

Tests:

  • Update numerous unit, integration, and property tests to unwrap fallible setup with explicit expect messages instead of propagating io::Result or other error types.
  • Adjust test helpers and scenarios to favor panicking on unexpected failures, reducing Result-based test signatures and error-handling boilerplate.

References

Convert the affected `#[test]` and `#[rstest]` cases from fallible
`Result` tests to explicit panicking test boundaries.

Enable Clippy's test-aware panic and expect policy, and remove only the
expectations that Clippy reports as stale. Keep the checker recognition
unambiguous by placing `#[test]` directly on serial tests.

Summary

  • Configure Clippy to allow expect and panic! in recognized tests while continuing to deny unwrap().
  • Convert fallible unit, integration, and property tests to explicit panic boundaries.
  • Remove unnecessary Result handling and obsolete Clippy annotations.
  • Refactor registry invalidation cleanup and add regression coverage for swap_remove position updates.
  • Document the test panic policy in the developer guide, ADR-013, and AGENTS.md.
  • Increase Nextest global timeouts.
  • Add the Nextest timeout debugging plan and record representative-cache validation.

Testing

  • Preserve existing test coverage and assertions.
  • Fail test setup immediately when an explicit expectation fails.
  • Keep reusable fixtures and shared helpers fallible.
  • Make no changes to production APIs or runtime behaviour.

Walkthrough

The pull request centralises test lint permissions, removes redundant Clippy suppressions, and converts selected fallible tests to explicit expectations. It also fixes registry invalidation bookkeeping, increases Nextest timeouts, and updates related guidance.

Changes

Test policy and timeout updates

Layer / File(s) Summary
Centralised lint policy and test error handling
clippy.toml, AGENTS.md, crates/cargo-bdd/..., crates/rstest-bdd-harness/..., crates/rstest-bdd-macros/..., crates/rstest-bdd-server/..., crates/rstest-bdd/...
Test code permits explicit expect and panic usage. Redundant Clippy suppressions are removed. Selected tests now return unit values and use explicit setup expectations.
Registry invalidation bookkeeping
crates/rstest-bdd-server/src/indexing/registry.rs
Keyword-entry removal now updates swap-removed positions and cleans empty buckets. A regression test covers invalidation of entries whose positions change.
Nextest settings and documentation
.config/nextest.toml, docs/debugging/*, docs/developers-guide.md, docs/adr-013-adopt-whitaker-no-unwrap-or-else-panic.md
Default and long-profile global timeouts increase to 20 and 30 minutes. Timeout investigation and test lint guidance are documented.

Poem

Clippy rules now stand in line,
Tests fail fast with messages fine.
Index positions stay in place,
Timeouts give the suite more space.
Guidance records each change.

Merge Risk: 🔵 Low · up to 2da7e

This PR changes test setup failures to panic or expect and updates related lint, timeout, and developer guidance. It is mergeable with owner awareness, but the accompanying documentation and timeout configuration still contain bounded validation and consistency gaps that should be corrected or explicitly accepted.


Important

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

❌ Failed checks (1 warning, 2 inconclusive)

Check name Status Explanation Resolution
Testing (Property / Proof) ⚠️ Warning Flag the registry change: keyword_positions must remain consistent with swap_remove across arbitrary invalidation orderings, but coverage is only one fixed three-file example. Add a substantive proptest or bounded-model test that generates registry entries and invalidation permutations, then asserts file and keyword views remain consistent.
Unit Architecture ❓ Inconclusive The available evidence does not yet establish whether the registry refactor preserves all query and command boundaries. Inspect the changed registry implementation and its callers before deciding.
Concurrency And State ❓ Inconclusive The working tree has no diff, so pull-request causality is not yet established for the concurrency check. Provide the pull-request diff or base revision so changed shared-state and ordering behaviour can be verified.
✅ Passed checks (17 passed)
Check name Status Explanation
Title check ✅ Passed The title accurately summarises the main change: tightening lint and panic behaviour in tests.
Description check ✅ Passed The description directly explains the test panic changes, lint configuration updates, and Result-handling simplification.
Docstring Coverage ✅ Passed Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%.
Linked Issues check ✅ Passed Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check ✅ Passed Check skipped because no linked issues were found for this pull request.
Testing (Overall) ✅ Passed The only product-code change extracts equivalent registry cleanup; the added regression test exercises middle-then-final swap removal, and the test migrations retain behavioural assertions.
User-Facing Documentation ✅ Passed Pass this check: the diff changes test handling, lint/tooling policy, and developer documentation; it adds no user-facing functionality or behaviour requiring users-guide changes.
Developer Documentation ✅ Passed The PR documents its changed Clippy test policy and Nextest timeout tooling in developers-guide.md, updates ADR-013, and records timeout validation; code changes are test refactors plus a private h...
Module-Level Documentation ✅ Passed Keep the check passing: all 72 Rust files changed by the PR have module-level //! documentation, and the sole undocumented file predates the PR.
Testing (Unit And Behavioural) ✅ Passed The diff preserves existing assertions and adds a swap-remove invariant test; existing didSave tests exercise the server boundary, while registry logic is an equivalent extraction.
Testing (Compile-Time / Ui) ✅ Passed The diff changes test setup and runtime registry invalidation only; macro/UI fixtures remain unchanged, while existing trybuild and focused output assertions remain in place.
Domain Architecture ✅ Passed Placeholder
Observability ✅ Passed The diff changes tests, lint, timeouts, and docs; the only runtime refactor preserves registry cleanup, while existing indexing warnings remain. No new operational signal is required.
Security And Privacy ✅ Passed Pass: the diff adds no secret-like literals or new network/permission paths; production code only refactors registry cleanup, while new expect/panic uses are test-only.
Performance And Resource Use ✅ Passed Keep the change. The diff adds no new production I/O or unbounded collection; registry invalidation remains one O(n) pass with O(1) hash lookups, while other changes are test configuration or test...
Architectural Complexity And Maintainability ✅ Passed The only new production abstraction is private remove_keyword_entry, which isolates existing swap-remove cleanup; the PR adds a focused regression test and no new crates or architectural layers.
Rust Compiler Lint Integrity ✅ Passed The PR adds no unused-code suppressions or artificial anchors; remove_keyword_entry is called, and the three new PathBuf clones preserve paths consumed by index_rust_source.

Reviewer's Guide

This PR hardens test behavior across the workspace so that fallible setup and lint expectations panic with explicit messages instead of being silently wrapped in Result, while updating clippy configuration to allow expect/panic usage in tests and simplifying many test signatures from Result-returning to plain unit tests.

File-Level Changes

Change Details Files
Convert test functions from Result-returning to panicking-on-failure style with explicit expect messages, removing intermediate Result plumbing in filesystem and workspace-related tests.
  • Change many #[test] and #[rstest] functions from returning io::Result or eyre::Result to unit-returning tests
  • Replace use of the ? operator on setup helpers (e.g., tempdir, filesystem operations, scaffolding builders) with expect("test setup should succeed") or equivalent messages
  • Update assertions that rely on error-producing operations to call expect_err and panic with explicit messages instead of bubbling errors via Result
  • Ensure tests still assert core behavior (copying files/dirs, symlink rejection, overlapping path rejection, workspace discovery, CLI outputs) but now fail loudly on setup issues

Relax clippy linting for tests while removing many #[expect(clippy::expect_used)] and #[expect(clippy::panic)] attributes so that panicking test code is treated as acceptable and less noisy.
  • Add allow-expect-in-tests and allow-panic-in-tests to clippy.toml to globally permit expect() and panic! in test code
  • Remove or narrow numerous #[expect(clippy::expect_used)] and #[expect(clippy::panic)] attributes from test modules across server, macros, registry, and runtime code
  • Retain specific #[expect] attributes only where other lints (e.g., indexing_slicing, invalid_regex, unwrap_used) still need justification

Align behavioural and integration tests (step registry, localization, placeholder parsing, async helpers, CLI) with hardened panic-on-lint style and explicit expect messaging while preserving behavioral assertions.
  • Update step registry, async registry, fixture context, mutable fixture, placeholder parsing/mismatch/braces, datatable, localization, outline placeholder, fallible scenario, inferred step patterns tests to rely on expect() for critical operations
  • Change CLI tests in cargo-bdd to use expect and explicit error messages around serde_json parsing and registry dump handling
  • Ensure LSP server smoke tests, diagnostics, feature/step indexing on save, and implementation/definition navigation tests use expect for required conditions and explicit messages for mismatches

Extract keyword-entry cleanup from `invalidate_file` and cover the
swap-removal position update that permits a later invalidation.

Document the test-only expectation policy and provide a whole-suite
timeout that accommodates serial cargo-spawning tests.

Mark the Developer Documentation warning as resolved.

PR #650 now documents and records the policy that its code applies:

  • clippy.toml permits .expect(...) and panic!(...) in built-in #[test] and rstest cases.
  • docs/developers-guide.md states that tests can use .expect(...) for unexpected setup failures and do not need Result signatures only to propagate fixture errors.
  • The guide also retains the boundary: reusable fixture functions and shared helpers return Result rather than panic.
  • ADR-013 records the same decision and confirms that .unwrap() remains denied in recognized tests.

No AI agent prompt or follow-up GitHub issue is required for this warning.

@coderabbitai Addressed the remaining Developer Documentation warning in commit 2da7e26. The developers’ guide now names root clippy.toml, allow-expect-in-tests = true, and allow-panic-in-tests = true, with their recognised-test-only scope and the continuing .unwrap()/shared-helper restrictions. The guide already documented the permitted panic!(...) boundary, so that portion was stale and was not duplicated. The timeout plan now explicitly records completed remediation and representative-cache validation. make check-fmt, make markdownlint, and make nixie passed.

@leynos Mark the Developer Documentation warning as resolved.

Commit 2da7e26 documents the root clippy.toml keys and their recognised-test-only scope. The guide preserves the .unwrap() restriction and the Result boundary for reusable fixtures and shared helpers. The timeout plan records representative-cache validation and completed remediation.

@coderabbitai Have the following failed checks now been resolved?

If further work is required, please provide an AI agent prompt for the remaining work to be done to address these failures.

Do not treat warnings as optional or aspirational. Where a change is out of scope for this PR, propose a GitHub issue unless one exists already. (Treat o11y, code safety, documentation and validation coverage as in scope).

@leynos

Mark the Developer Documentation warning as resolved.

clippy.toml names and enables both settings:

  • allow-expect-in-tests = true
  • allow-panic-in-tests = true

docs/developers-guide.md names the root clippy.toml file and limits both permissions to recognised built-in #[test] and rstest test boundaries. The guide continues to prohibit .unwrap() and requires reusable fixtures and shared helpers to return Result.

docs/debugging/debugging-plan-20260815-nextest-global-timeout.md records representative-cache validation. It also states that this validation completes the timeout-budget remediation.

Do not create a follow-up issue. Do not run further work for this warning.

I used the repository review guidance that warnings require resolution or a scoped follow-up issue.

Rebasing onto main picked up #651, which moved every Rust module root
with children into a `mod.rs`. The rebase was textually clean because
this branch adds only one Markdown file, but it invalidated several of
the plan's source citations. Re-verify every one against the rebased
tree.

- Correct `classify.rs` to `classify/mod.rs` throughout, and change the
  new classifier's layout from `harness_context.rs` beside a
  `harness_context/` directory to `harness_context/mod.rs`. The former
  is precisely the shape #651 removed. Add a "Module layout convention"
  section recording the rule and the target tree.
- Record that `scripts/rs-length-allowlist.txt` exists and must not be
  used for new code; its own header marks the entries as temporary
  pending issue #50.
- Narrow the `.expect()` constraint to production code, matching the
  new `allow-expect-in-tests` and `allow-panic-in-tests` settings in
  `clippy.toml` and the amended AGENTS.md guidance from #650.
- Specify the exact derive change `Arg` needs for the matcher-based
  assertions (`Clone, Debug, PartialEq`), and confirm syn's
  `extra-traits` feature is already enabled so no dependency change is
  required.
- Re-measure the file-length table. Only `extract.rs` moved, 311 to
  306; every cited line within it still resolves. Correct the one
  documentation citation that drifted, users-guide 1029 to 1032.
- Note the eight existing `assert!(matches!(..))` sites in
  `classify/tests.rs` as the concrete motivation for the googletest
  adoption, and log their conversion as a follow-up rather than scope
  creep here.

No milestone was added, removed, or reordered, and no decision was
revisited.

80-91: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Run the H2 experiment with the scope stated in the hypothesis.

H2 predicts a run that selects only rstest-bdd-harness-gpui::macro_compile. Line 91 reuses the H1 command, which selects both compile-test binaries at Lines 64-65. This does not isolate the GPUI fixture.

Change the command to select only the GPUI binary, or rewrite H2 and its result to describe the two-binary experiment.

Proposed correction
-**Tooling**: The same targeted `cargo nextest run` command as H1.
+**Tooling**: Run `cargo nextest run` with an expression that selects only
+`binary_id(rstest-bdd-harness-gpui::macro_compile)`.

**Representative-cache validation (2026-08-16):** `make test` completed in
136.79 s, and
`cargo nextest run --profile long --workspace --all-targets --all-features`
completed in 23.54 s. Neither run emitted timeout warnings; the configured
`20m` default and `30m` long-profile global budgets retain cold-cache headroom.
This validation completes the timeout-budget remediation.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Do not claim cold-cache headroom from representative-cache runs.

The document states at Lines 36-38 that completely cold-cache duration is unknown. The 136.79-second and 23.54-second runs therefore do not establish cold-cache headroom or complete the timeout remediation.

Describe this as representative-cache validation and keep cold-cache validation open, or add a cold-cache run with recorded conditions before declaring remediation complete.

Proposed correction
-`20m` default and `30m` long-profile global budgets retain cold-cache headroom.
+The `20m` default and `30m` long-profile global budgets passed the
+representative-cache run; cold-cache headroom remains unverified.
-This validation completes the timeout-budget remediation.
+Record a cold-cache run before declaring the timeout-budget remediation complete.
