Spec Drift Breaks Tests

spec-drift-inconsistent-logic

Integration tests fail with confusing downstream symptoms when implementations drift from an authoritative spec—e.g., retrieval scoring excludes required recency/boost rules or auth state/tier logic is inconsistently framed—causing eligibility and gating mismatches that ripple through the test stack.

PointerEvent wasn't properly simulated in the test environment

implementation and tests still encoded dual-mode behavior — A TypeScript standalone gateway migration was documented as clean-break standalone-only. Tension: default mode was plugin, default port was the old host-gateway port, an env flag switched standalone behavior, legacy env fallbacks were still honored, and post-cutover tests rejected the intentionally preserved external workspace path.

the tests timeout — when using MSW + Testing Library + Tanstack Query. Outcome: It turns out there was a test setup preventing the code to resolve.

passing health checks but its Bash cutover and post-cutover verification scripts exited early or misreported failure — A Node/TypeScript gateway cutover harness. Tension: The scripts used `set -euo pipefail`, post-increment arithmetic such as `((elapsed++))` / `((PASS_COUNT++))`, brittle command-output parsing for npm preflight status, and exact JSON-shape assumptions for RPC verification.

Outcome: integration tests fail with confusing downstream symptoms.

Between steps 4 and 5, I'd like a quality gate established where if 4 fails, the user cannot run 5. — A release is queued to staging automatically A Cypress E2E test is executed, to test the results in staging. The user manually releases to production. Tension: if 4 fails, the user cannot run 5. Outcome: How can I achieve this?

we get a lot of random test failures on our system tests — The Github action runner docker image for Ubuntu 22.04 upgraded chromedriver from 120 to 121. Tension: After that we get a lot of random test failures on our system tests. Outcome: Anyone else have this problem and have solved it?

Privacy pipeline spec changed from retaining encrypted raw text to default-discard, but existing schema and write paths still assumed raw retention and async-only LLM review

Unit tests cannot deterministically simulate S3 upload failure

Adding nondeterministic compilation breaks reproducible builds — users will no longer be able to verify the packages they install. Tension: this security measure is a good example of so-called security theater. Outcome: it will not provide additional security for most of the cases, but will greatly complicate a lot of things.

javax.lang.model.element.UnknownElementException: Unknown element: "params" — using the javax.tools.DocumentationTool to parse the Documentation of my source code base. Tension: The stack trace as can be seen is when the record Component is visited. Outcome: It is triggering an javax.lang.model.element.UnknownElementException exception when a record method parameter.

All test fails with `NoSuchMethodError` — using embedded kafka from `org.springframework.kafka:spring-kafka-test:3.3.5` for testing purposes. Tension: that is thrown inside of `org.apache.kafka:kafka_2.13:3.8.1`. Outcome: Everything worked until I had to change version of `org.apache.kafka:kafka-clients` from `3.8.1` to `3.9.1`.

Need to check DB state in an integration test without adding repository select methods

one of my integration tests affects the other. Tension: Will affect this get list of customer test.

JCStress reports FORBIDDEN outcomes (state marked finished but operation result not recorded) when using two identical reader actors, even though the same behavior with a single reader actor produces only ACCEPTABLE results.

When I run tests in parallel, I get random failures — one test interferes with the cache of another test. Tension: one test interferes with the cache of another test.

A Tier 3 integration test harness for the Codex CLI stopped detecting MCP tool calls. — after CLI flag, model, and JSON stream schema drift. Tension: The CLI rejected deprecated unattended flags unless the workspace trust check was bypassed, the harness defaulted to an unsupported model for the current account, and the parser only handled older top-level JSON events.

every mocked fetch test short-circuited with a missing API-key error — web-search handler tests that stubbed an API-key environment variable. Tension: ESM imports are evaluated before the test's stub took effect.

The main risk was letting the new database dependency make normal runtime boot or the test suite fail — A TypeScript/Node agent runtime needed a new pgvector/Postgres memory subsystem. Tension: Postgres or pgvector were unavailable. Outcome: Implemented the memory service as an optional subsystem.

retrieval scoring omitted recency decay, normalized momentum, live-state retrieval bias, and multiplicative tier boost — A Phase 3 memory subsystem review found deviations from the authoritative memory spec. Tension: short-term memories were still eligible for episodic retrieval; the memory daemon did not reconnect after LISTEN connection errors; ILIKE patterns used unescaped user text; extractor errors could disappear from fire-and-forget timeouts; and memory migrations lacked partitioning/seed data details. Outcome: Read the corrective spec and compared it against the current TypeScript memory implementation, migrations, and tests.

developers are unsure which [Sync] flags to use and when — In s&box multiplayer. Tension: Without the right flags, values either don't replicate or replicate from the wrong authority.

After a documentation/template merge. Tension: The intended behavior was only that search remains the primary error-handling entry point, while the template may still list richer graph traversal tools elsewhere. Outcome: a behavioral template test failed.

This created drift between human install docs, machine-readable agent manifests, llms.txt references, and actual tested client behavior.

Features built on optional capabilities silently degrade across the client matrix. Outcome: Community 4's transport bugs and Community 103's capability detection failures are two symptoms of the same architectural constraint.

replace a binary cold/warm mode with sequential wave framings — TypeScript benchmark demo. Tension: scattering auth state across prompts, orchestrator, dashboard, and tests. Outcome: no-tool waves to receive graph instructions or authenticated waves to miss write access.

Checked the production page and direct graph endpoints, then inspected the API stream route and client hook. — The significant-tier route had no explicit warning/error frame contract and could proceed with an empty allocation or empty result. Tension: The client treated a zero-node stream as a normal preview fallback without surfacing why. Outcome: Existing tests covered normal compact frames but did not assert empty significant-tier recovery or diagnostic frames.

Integration tests fail with `PostgresError: update or delete on table "X" violates foreign key constraint "Y_fkey" on table "Z"` — when the teardown deletes a parent row (e.g., a test agent/user). Tension: Becomes flaky-then-broken the moment a new code path writes those audit rows synchronously on the same code path the test exercises. Outcome: one test file fails first, but 10+ other test files have the same latent dependency.

Implementing a validation suite for an anonymization-pipeline backfill across "Cohort-D" tables — system-rendered / agent-internal: messages, message_audits, message_requests, scoped_messages, notifications, bug_reports, contact_submissions, chronicle_entries/crystals/lessons. Tension: Spec required 9 distinct cross-cohort invariants in a single validate.ts script, each with positive AND negative test coverage, runbook STOP criteria matching an existing A1 runbook shape, and stripping legacy KMS column-name references.

naive optimistic updates either (a) flicker because the next server [REDACTED]shot wipes them or (b) get stuck because you can't — In a server-authoritative realtime app (game tick, collaborative doc). Tension: the next server [REDACTED]shot wipes them. Outcome: Switching to derive-from-[REDACTED]+[REDACTED] made the whole thing trivially correct.

Long-session continuity tests also produced false failures — when ACK tokens appeared in the user's own prompt or were altered by Markdown rendering. Tension: ACK tokens appeared in the user's own prompt or were altered by Markdown rendering. Outcome: Use Markdown-safe alphanumeric ACK markers, wait specifically for an assistant-role ACK before navigating away, and classify browser events into fatal, expected fresh-auth noise, unexpected browser errors, journal failures, and journal warnings.
