LCORE-2343: implement behave step definitions for unified-mode feature files by max-svistunov · Pull Request #2448 · lightspeed-core/lightspeed-stack

max-svistunov · 2026-08-17T09:33:43Z

Description

Implements LCORE-2343 for the five unified-mode-*.feature files authored spec-first in LCORE-2341 (PR #2020), and unskips them. Reworked after QE review to respect the e2e/integration boundary: e2e steps never touch src/. The first cut ran src/lightspeed_stack.py and src/ogx_configuration.py as subprocesses for validation, migration and synthesis assertions; those are integration tests, and they now live in tests/integration/. What stays in e2e is exactly what only a deployed stack can show.

The boundary, written down

docs/testing/e2e_testing.md gains a "Choosing the Test Layer: E2E or Integration?" section — three-layer table, the rule, and a one-question test (would this scenario run unchanged against a container image with no source checkout?). Cross-referenced from docs/testing/testing.md, tests/e2e/README.md (whose "full guide" link pointed at a file that does not exist) and the "What to Test" list in tests/integration/README.md. The same rule applies to the other spec-first feature-file tickets in flight (LCORE-1673/2230 compaction, LCORE-3387/3388 guardrails, LCORE-3375/3376 Confluence), so it is worth agreeing once here.

Scenario → layer mapping

#	Scenario	Called src?	Already covered in `test_unified_synthesis.py`	Now
V1	`inference.providers` + `library_client_config_path` fails at load	yes	`test_load_rejects_inference_providers_and_legacy_path_together`	integration: CLI-contract test, parametrized
V2	`llama_stack.config` + `library_client_config_path` fails at load	yes	`test_load_rejects_config_block_and_legacy_path_together`	integration (same test)
V3	`config_format_version: legacy` on a unified body fails at load	yes	—	integration: CLI parameter and in-process load test (only R11 coverage anywhere)
M1	`--migrate-config` produces a unified config from a legacy pair	yes	`migrate_config_dumb` in-process; CLI flags, rc and 0600 untested	integration: CLI-contract test (flags, rc, content, 0600, round trip)
M2	migrate then synthesize round-trips	yes	`test_migrate_then_synthesize_round_trip_without_enrichment`	dropped — duplicate
M3/M4	migrated config boots and serves queries (library / server)	yes, as a `Given`	—	e2e, edited: boots a committed `lightspeed-stack-unified-migrated.yaml`; drift guard in integration; `@openai-only`
S1/S2	`native_override` replaces scalar / list wholesale	yes	`test_native_override_deep_merge_through_real_load`	dropped — covered
S3	emitted secrets stay `${env.…}` references on disk (R6)	yes	—	integration, in-process
S4	synthesized run.yaml written 0600 (R10)	yes	`test_synthesized_file_written_owner_only`	dropped — covered
S5	`--synthesized-config-output` overrides the location	yes (`Popen` of the service)	—	integration, in-process via `AsyncOgxClientHolder._synthesize_library_config`
S6/S7	synthesized path is logged at startup (library / server)	no — `docker logs`	—	e2e
B1–B8	unified config boots and serves (4 shapes × 2 modes)	no	—	e2e
L1/L2	legacy two-file config still boots (library / server)	no	—	e2e

24 scenarios → 14 stay e2e (12 untouched, M3/M4 edited); 10 leave e2e — 4 already had in-process coverage, 6 got integration tests. steps/unified_mode.py: 508 lines / 16 patterns → 60 lines / 1 pattern.

What is in the PR

Integration — tests/integration/test_unified_mode_cli.py (new): the real entrypoint as a subprocess from the repo root; invalid configs exit non-zero with the right message; --migrate-config writes owner-only, carries native_override, drops library_client_config_path, round-trips through synthesis; the committed migrated e2e fixtures match today's CLI output (regeneration command in the docstring). test_unified_synthesis.py gains R6, R11 and the --synthesized-config-output override. Inputs under tests/configuration/unified-mode/.
E2E — unified-mode-validation.feature removed; -synthesis.feature keeps the two startup-log scenarios; -migration.feature keeps the two boot scenarios against the committed fixture. The never-booted fixtures leave tests/e2e/; the fixtures README documents what remains. Step module reduced to the mode-aware container-log step (server mode inspects the llama-stack container, which is the one that synthesizes — deviation documented in the step).
Gating (unchanged from the first cut): @skip-in-prow on all features (Docker dependencies; Prow wiring is separate work), @openai-only + before_scenario hook keyed on E2E_DEFAULT_PROVIDER_OVERRIDE for fixtures that hardcode openai — now also on M3/M4.
Harness fix (unchanged): restart_container waited on Docker health, which can report healthy before uvicorn binds; the HTTP-ready wait is now wired into every lightspeed-stack restart, with a single monotonic deadline.
Startup-log evidence scoped to the current boot: docker logs accumulates across docker restart and the CI baselines already synthesize on the first compose boot, so the log step now reads only since the container's StartedAt; server mode additionally requires the fallback Using original config: line to be absent on that boot.
One restart wait path: restart_container already waits for health then HTTP; the redundant explicit waits in the proxy/TLS steps and the no-op wait_http flag are gone.
Fixtures: lightspeed-stack-legacy.yaml restores the library-mode legacy boot coverage that LCORE-2342 silently removed (R2).

Gherkin edits

LCORE-2343 requires the .feature files be taken as-is, with any edit documented. Edits, none of which weakens a surviving scenario:

@skip → @skip-in-prow (all files) — the unskip this ticket exists to perform.
@openai-only on the two inference.providers boot scenarios and on the two migrated-config boot scenarios — their fixtures hardcode openai.
unified-mode-legacy.feature: library-mode Given uses lightspeed-stack-legacy.yaml (see Fixtures above).
unified-mode-migration.feature: two scenarios retitled from "drives byte-identical Llama Stack behavior" to "boots and serves queries" — that is what they assert.
Test-layer move: unified-mode-validation.feature removed; S1–S5 and M1–M2 removed; the --migrate-config Given removed from M3/M4 in favour of the committed fixture. Each has an integration test or existing in-process coverage — see the mapping.

Testing

Integration (new + existing, in-process and CLI):

uv run pytest tests/integration/test_unified_mode_cli.py tests/integration/test_unified_synthesis.py -q
26 passed

E2E dry run — zero undefined steps across the four remaining features:

uv run behave --dry-run -f plain tests/e2e/features/unified-mode-*.feature
4 features, 14 scenarios, 133 steps — 0 undefined

E2E in CI: the @cfg_unified features run in the other shard (E2E: library / ci / other, E2E: server / ci / other); both were green on the previous head and are the gate for this one.

Lint on changed files: black, ruff, pydocstyle, pyright, mypy (Makefile flags) clean; bandit findings are the LOW assert/subprocess classes every test module carries.

Walkthrough

The change adds unified-mode e2e fixtures and Behave steps for validation, migration, synthesis, provider handling, and runtime checks. It also enables non-Prow execution, adds legacy fixtures, and waits for HTTP readiness after container health.

Changes

Unified-mode end-to-end coverage

Layer / File(s)	Summary
Unified configuration matrix `tests/e2e/configuration/unified-mode/...`	Adds library-mode and server-mode fixtures for profiles, providers, config-only cases, and scalar/list native overrides.
Legacy validation and migration fixtures `tests/e2e/configuration/library-mode/...`, `tests/e2e/configuration/unified-mode/...`, `.gitignore`	Adds legacy fixtures, invalid configuration combinations, migration inputs, and an ignore rule for generated migrated files.
CLI-backed unified-mode steps `tests/e2e/features/steps/unified_mode.py`	Adds subprocess-based validation, migration, synthesis, artifact, secret, permission, custom-output, and log assertions.
Scenario gating and runtime readiness `tests/e2e/features/*.feature`, `tests/e2e/features/environment.py`, `tests/e2e/utils/utils.py`	Changes skip tags, gates OpenAI-only scenarios by provider, and waits for the Lightspeed Stack liveness endpoint after restart.

Merge Risk: 🔵 Low · up to 924c0

This PR enables unified-mode end-to-end coverage for boot, validation, migration, and synthesis. It is mergeable with owner awareness for constraining unauthenticated test listeners, requiring the startup log to include a synthesized path, bounding readiness waits, and removing the YAML formatting issue; these are localized test-environment risks that could expose a test service or weaken failure detection.

Create tests/e2e/configuration/unified-mode/ with library-mode/server-mode variants (same two-subdir layout configure_service resolves), covering the five unified-mode feature files: - unified-providers: minimal unified config driven only by top-level inference.providers over the default baseline (R1/S5); openai-specific. - unified-config-only / unified-relative-profile: profile: run.yaml — the CI-materialized repo-root run.yaml as baseline, provider-agnostic (R1/R8; two files because the features pin the intents separately). - unified-absolute-profile: container-absolute profile paths, differing per mode subdir (/app-root vs /opt/app-root mounts). - unified-native-override-{scalar,list}: R5 replacement semantics fixtures, synthesis-only, never booted. - invalid-{providers,config}-and-legacy: mutual-exclusion validation fixtures (R3); invalid-version-legacy-unified-body: R11 marker mismatch (needs LCORE-2872's cross-validation to fail for the right reason). - legacy-for-migration: legacy half of the migration fixture pair, kept free of enrichment sections so migrate-then-synthesize round-trips losslessly (LCORE-3370). Every fixture is validated against the real Configuration model: bootable ones load, invalid ones fail with the intended error. The test-generated lightspeed-stack-unified-migrated.yaml is gitignored, and the directory README documents each fixture's purpose.

…d fixture LCORE-2342 migrated the standard library-mode baseline to unified mode (config.profile: run.yaml), which silently changed what unified-mode-legacy.feature's library scenario exercises: it now boots the unified baseline, not the deprecated two-file path, so R2's library-mode legacy coverage was gone. Add lightspeed-stack-legacy.yaml — identical to the baseline except its llama_stack block uses the true legacy shape (use_as_library_client + library_client_config_path: run.yaml, no synthesis input) — and point the library scenario's Given at it. This is the one deliberate Gherkin edit in LCORE-2343, agreed with Maxim in planning; the server-mode scenario is untouched since container-side enrichment there is genuinely legacy.

Add tests/e2e/features/steps/unified_mode.py — the 16 step patterns the validation, migration, and synthesis features need (boot and legacy resolve entirely through existing generic steps). Per the planning decisions: - All artifact steps operate on the ON-DISK configuration (the repo-root lightspeed-stack.yaml copy configure_service applied), never the live service. - Validation runs the service CLI (--dump-configuration) as a black-box subprocess from the repo root and asserts a non-zero exit, so the error-contains assertions can never pass against a healthy load. - Migration runs the real --migrate-config CLI; the output lands in the active mode subdir under the gitignored name later Gherkin references, and is cleaned up per scenario. - Synthesis runs the config CLI exactly as the server entrypoint does (unified auto-detection -> synthesize_to_file, giving the 0600 mode the permissions scenario asserts). Round-trip and override assertions parse YAML and compare data, never bytes; override assertions are self-referential against the fixture's native_override and additionally assert the baseline differed, so replacements can't pass vacuously. - The --synthesized-config-output scenario launches a short-lived local service from the library-mode fixture variant on a rewritten port and polls for the custom output file (the flag is library-mode-only by design; running containers cannot be restarted with new CLI args). - The startup-log step is mode-aware: in server mode the synthesis evidence is emitted by the llama-stack container (entrypoint + CLI), not the lightspeed-stack container the Gherkin names — asserted against the synthesizing container with the rationale documented in the step. behave --dry-run over the five features: 24 scenarios, 200 steps, zero undefined.

Tag all five unified-mode features @skip-in-prow: the new steps rely on Docker containers and local subprocesses, neither of which exists in the Prow environment (existing convention, handled in before_scenario). Add an @openai-only tag on the two inference.providers boot scenarios and a matching before_scenario skip keyed on E2E_DEFAULT_PROVIDER_OVERRIDE: the providers workflow runs the full unsharded test list against azure/watsonx/bedrock matrices, and the unified-providers fixture hardcodes an openai provider that cannot serve those models' queries. Profile-based fixtures stay provider-agnostic (they consume the CI-materialized run.yaml) and need no gating.

@Skip

Remove the @Skip placeholder tag from the five unified-mode features: the step definitions and fixtures they need now exist. The features keep @skip-in-prow (Docker/subprocess dependencies) and stay in test_list.txt under @e2e_group_2, so CI shards pick them up via 'not @Skip and @e2e_group_2' and local runs via --tags=-skip.

restart_container waits on docker health, but docker can report healthy before uvicorn binds the published port — the exact race wait_for_lightspeed_stack_http_ready documents and was, until now, only closed in the proxy steps. The unified-mode boot scenarios are the slowest restarts in the suite (first unified/default-baseline boots) and hit that window reliably: the restart step passed while the following readiness GET got connection-refused. Call the existing HTTP-ready wait from restart_container for the lightspeed-stack container, closing the race for every restarting scenario; when the port is already accepting, the first poll returns immediately.

--migrate-config writes its output 0600 (R10: migrated files may carry lifted secrets), but the boot scenarios copy that file to the repo root for the container to consume, and the container user cannot read a host-owned 0600 file — the migrated-config boot scenario died on config read. Relax the harness copy to 0644 after a successful migration; the fixture pair is env-reference-only by design, so no secret can leak.

The library-mode legacy fixture declared its BYOK store under a top-level byok_rag key with rag_type, and its tool retrieval sources under rag.tool. LCORE-1426 (commit c1de7f9) refactored RAG configuration into a single rag section: stores moved to rag.byok.stores, retrieval sources to rag.retrieval.tool.sources, and RagStore.rag_type was replaced by RagStore.backend, whose validator accepts only the values in SUPPORTED_RAG_BACKENDS (faiss, pgvector). Configuration models inherit ConfigurationBase with extra=forbid, so after rebasing onto main this fixture raised two extra_forbidden validation errors (rag.tool and byok_rag) and the config could not be loaded at all, failing every legacy library-mode scenario that consumes it. Move the store under rag.byok.stores, replace rag_type: inline::faiss with backend: faiss, and nest the retrieval source list under rag.retrieval.tool.sources. score_multiplier, db_path, embedding_model, embedding_dimension and vector_db_id are unchanged and remain valid RagStore fields. The source id stays e2e-test-docs so the validate_retrieval_sources model validator still resolves it against the declared store.

The migration step ran --migrate-config straight into the fixture directory and then chmod'ed that file to 0644 so the container user could read the copy configure_service places at the repo root. That widened the CLI's own output, which is the artifact R10 governs: migrated configurations may carry secrets lifted out of the legacy run.yaml, and the CLI deliberately writes them owner-only (it logs "mode 0600" when it does). The harness therefore destroyed the property it exists to protect, and no scenario noticed because the 0600 assertion only covers the synthesized run.yaml, not the migrated config. A fixture that ever carries a real secret would have had it published world-readable with nothing failing. Migrate into a scratch directory instead, assert the CLI wrote 0600 there, and publish a separate deliberate 0644 copy under the name the Gherkin steps reference for configure_service to boot. The mode relaxation now applies to a copy that exists only for the harness, the CLI artifact keeps its mode, and the R10 guarantee gains the direct assertion it previously lacked.

…sages The startup-logging step matched "Using synthesized Llama Stack config" in library mode and "Wrote synthesized Llama Stack configuration" in server mode. The OGX rename (PRs lightspeed-core#2516 and lightspeed-core#2547) replaced both: client.py now logs "Using synthesized OGX config at %s" and llama_stack_configuration.py logs "Wrote synthesized OGX configuration to %s (mode 0600)". Neither scenario started failing, which is the reason to fix it now rather than after a real breakage. Library mode kept passing only because the sibling alternative "synthesized.*run\.yaml" incidentally matches the OGX line, the synthesized file being named run.yaml; server mode kept passing on the entrypoint's own "Using generated config:" and "mode auto-detected" echoes. Both scenarios were therefore asserting something other than the message they name, and would have gone silently unprotected the moment the output filename or the entrypoint echoes changed. Point the patterns at the current messages and record in the docstring where each one is emitted, so the next rename has an obvious place to look.

Both scenarios were titled "drives byte-identical Llama Stack behavior", but neither compares anything byte for byte: they boot the migrated configuration, assert readiness returns 200, and assert a query returns 200. The byte-level claim belongs to "migrate then synthesize round-trips to the original run.yaml" earlier in the same file, which does compare parsed data. Feature files are read as specification, so a title that overstates its scenario misleads anyone auditing what unified-mode migration is actually covered by. Rename both to "boots and serves queries", which is what the steps verify. No step definition, CI tag filter or test_list entry references either title, so this is a documentation-only change.

YAMLlint reports "too many blank lines (1 > 0)" at the end of lightspeed-stack-legacy.yaml, which fails the configured formatting check. Strip the trailing newline so the file ends immediately after its last mapping entry.

…message The startup-log step accepted "mode auto-detected" in server mode and a bare "Using synthesized OGX config" in library mode, neither of which carries a path. scripts/llama-stack-entrypoint.sh echoes "(mode auto-detected)" unconditionally and *before* it runs the config CLI, so a scenario asserting R10 ("the synthesized path is logged at startup") passed even when synthesis had failed outright — the precise failure the assertion exists to catch. Require a non-empty path in every alternative: "Using synthesized OGX config at <path>", "Wrote synthesized OGX configuration to <path>", and the entrypoint's "Using generated config: <path>", which unlike the auto-detect echo is only emitted after a successful generation. Verified against the three real messages, and that the pre-synthesis echo is now rejected.

…dline wait_for_lightspeed_stack_http_ready counted attempts rather than tracking wall-clock time, so its real ceiling was the per-request timeout plus the sleeps: 80 * 5s + 79 * 1.5s = 518.5s. The AssertionError reported only the backoff total, "~120s", understating the worst case by a factor of four. That gap matters more since this branch wires the wait into every lightspeed-stack restart rather than only the proxy steps: a container that never binds its port could stall a run for over eight minutes per restart, across the eight call sites of restart_container, while the failure text claimed two. Replace the attempt counter with one monotonic deadline covering both the requests and the sleeps, clamp each request timeout to the time remaining, skip a final sleep that would overrun the budget, and report the attempts and elapsed time actually spent. The default budget is 120s, which is what the old message always claimed the bound was.

QE review of the unified-mode step definitions surfaced a rule the repository had been applying by convention but had never written down: an e2e step must not import from, invoke, or shell out to anything under src/. The moment it does, the scenario stops proving what a deployed stack does and starts proving what a checked-out source tree does, which is an integration test. Add a "Choosing the Test Layer: E2E or Integration?" section to docs/testing/e2e_testing.md with the three-layer table, the rule, the "would it run against a container image with no source checkout?" test, and the concrete consequences for configuration validation, migration and synthesis (integration) versus boot and log-evidence scenarios (e2e). Cross-reference it from docs/testing/testing.md, tests/e2e/README.md and the "What to Test" list in tests/integration/README.md, which gains a "CLI contracts" item for repo entrypoints run as subprocesses. tests/e2e/README.md linked docs/e2e_testing.md, which does not exist; the guide lives at docs/testing/e2e_testing.md. Fix the link.

… the integration layer The unified-mode e2e step definitions ran src/lightspeed_stack.py and src/ogx_configuration.py as subprocesses for validation, migration and synthesis assertions. Those are integration concerns (see the test-layer boundary in docs/testing/e2e_testing.md); move them here, alongside the in-process synthesis suite from LCORE-2747 that already covered most of the same ground. tests/integration/test_unified_mode_cli.py (new) runs the real entrypoint from the repository root the way operators and the container entrypoint do: - --dump-configuration exits non-zero and names the problem for the three invalid shapes (inference.providers plus a legacy path, a config block plus a legacy path, config_format_version: legacy on a unified body). - --migrate-config writes the unified file owner-only (R10), with the run.yaml carried as native_override and library_client_config_path dropped, and the result synthesizes back to the pair's run.yaml data. - The committed lightspeed-stack-unified-migrated.yaml e2e fixtures match today's CLI output for both modes, so the migration boot scenarios can consume a committed artifact instead of generating one in a step; the docstring carries the regeneration command. tests/integration/test_unified_synthesis.py gains the three assertions the e2e scenarios had and this file lacked: emitted secrets stay ${env.NAME} references on disk (R6), config_format_version: legacy on a unified-shaped body fails the real load (R11), and LIGHTSPEED_STACK_SYNTHESIZED_CONFIG_PATH (set from --synthesized-config-output) redirects library-mode synthesis and leaves the default path untouched. native_override replacement (R5), the 0600 output mode (R10) and the migrate-then-synthesize round trip were already covered and are not duplicated. The CLI tests take their inputs from tests/configuration/unified-mode/, the integration fixture tree, with the legacy path pointed at tests/configuration/run.yaml so the captured failure is the intended cross-field error rather than a missing file.

…e features Apply the test-layer boundary: e2e steps observe the deployed stack from outside and never touch src/. Of the 24 unified-mode scenarios, 14 did that already (boot, legacy, startup-log evidence) and stay as they are; 10 exercised repo CLIs and now live in tests/integration (previous commit). - unified-mode-validation.feature is removed: all three scenarios are CLI contract tests. Dropped from test_list.txt. - unified-mode-synthesis.feature keeps the two startup-log scenarios, the one thing only a running stack can show; native_override replacement, env-reference secrets, the 0600 mode and --synthesized-config-output are covered in-process. - unified-mode-migration.feature keeps the two "migrated configuration boots and serves queries" scenarios. They used to generate their input by running --migrate-config inside a Given; they now boot a committed lightspeed-stack-unified-migrated.yaml fixture per mode, generated once from lightspeed-stack-legacy-for-migration.yaml and tests/e2e/configs/run-ci.yaml and guarded against CLI drift by test_unified_mode_cli.py. The fixture inlines the openai run-ci.yaml, so both scenarios carry @openai-only like the other provider-specific boots. The .gitignore entry for the generated file goes away with the step. - The migrate-then-synthesize round-trip scenario is dropped as a duplicate of the in-process test that already existed. steps/unified_mode.py shrinks from 508 lines and 16 patterns to the single mode-aware container-log step. The never-booted fixtures (three invalid shapes, two native_override shapes, both mode variants) leave the e2e tree; the fixtures README documents what remains and why. Gherkin edits are limited to removing scenarios and the generating Given, plus the @openai-only tags; no surviving step was weakened.

The "container logs contain synthesized run.yaml" step read the container's whole log. docker logs accumulates across docker restart, and the CI baseline configurations already synthesize (library mode) or generate (server mode) on the very first compose boot, so the step could pass on a line written long before the scenario applied its unified fixture — R10 was not actually being asserted. Read only the lines since the container's current StartedAt (docker inspect), i.e. the restart the scenario just performed. In server mode the entrypoint echoes the same "Using generated config" line for the legacy-enrichment branch, so the step also requires that the fallback "Using original config:" did not appear on this boot; with a unified fixture applied, a successful generation on this boot is a synthesis. The "Wrote synthesized OGX configuration to" alternative stays accepted but is not relied on: the config CLI never configures logging, so that INFO line is dropped in the llama-stack container. Also collapse the LCS restart to a single wait path. restart_container already waits for Docker health and then for HTTP on the published port (the harness fix earlier in this branch), which made the explicit wait_for_lightspeed_stack_http_ready calls in the proxy and TLS steps redundant and turned restart_lightspeed_stack_service's wait_http flag into a no-op with a docstring that said the opposite. Remove both; the degraded-mode caller drops the dead argument. The integration legacy-pair fixture named tests/configuration/run.yaml as its library_client_config_path while the migrate test passes tests/e2e/configs/run-ci.yaml as --run-yaml; point the fixture at the pair that is actually migrated.

The drift-guard docstring spelled out both fixture paths on single lines, which pylint rejects at 100 columns. Factor the mode directory into a variable in the recipe.
