Background job and queue testing: 7 skills (sidekiq-tests, celery-tests, bullmq-tests, sqs-patterns, rabbitmq-patterns, cron-job-test-author, idempotency-test-author).
Authors and runs Celery task tests in Python - `pytest-celery` fixtures (`celery_app`, `celery_worker` per-test, `celery_session_worker` per-session); `task_always_eager` config NOT recommended for unit tests; `apply()` for synchronous test invocation; mock-and-patch retry patterns via `unittest.mock.patch` on `task.retry`. Use when the user works with Celery task workers and needs unit / integration tests across function-style or class-style tasks.
Build-an-X for cron / scheduler job tests - cron-expression validation patterns (5-field standard `min hour day-month month day-week` + 6-field with seconds + named-list extensions), DST + leap-day edge cases, missed-execution detection (machine downtime catch-up), overlapping-run protection (lock + stale-lock recovery), timezone semantics. Use when authoring tests for cron jobs, Kubernetes CronJobs, BullMQ repeat-jobs, Sidekiq schedulers, or any time-based job runner.
Build-an-X for idempotency tests in any async/job/API context - idempotency-key handling (per Stripe / AWS prescriptive guidance pattern), retry-safe semantics (exactly-once vs at-least-once vs at-most-once), side-effect commutativity verification, fingerprint-based dedup, idempotency-window tuning. Use when authoring tests for any system where the same input could be processed twice (SQS Standard at-least-once, RabbitMQ requeue, retry-on-error logic, webhook redelivery, browser double-click, mobile-network retry).
Tests Apache Kafka consumer and producer logic across KafkaJS (Node.js), kafka-go (Go), and Spring Kafka (Java) - spins up a real broker via the Testcontainers Kafka module, asserts offset management and consumer-group rebalance behavior, distinguishes at-least-once from exactly-once (EOS / transactions), validates idempotent producer configuration, and routes unprocessable messages to a dead-letter topic. Use when the user works with Kafka producers or consumers in any language and needs integration or unit tests that exercise delivery semantics, offset commits, rebalance handling, or dead-letter routing.
Tests RabbitMQ producer/consumer interactions - supports AMQP 0.9.1 and AMQP 1.0 protocols across 6 tutorial patterns (Hello World, Work Queues, Publish/Subscribe, Routing, Topics, RPC) plus Publisher Confirms; consumer ack/nack/requeue patterns; durable queues + persistent messages; quorum vs classic queue; tests via Testcontainers RabbitMQ image or LocalStack-equivalent. Use when the user works with RabbitMQ producers/consumers (pika, amqplib, RabbitMQ.Client, spring-amqp) and needs unit/integration tests.

A rigorously curated quality-engineering plugin marketplace for Claude Code. 77 plugins, 695 components, every one rating-gated before merge.
d6 floordocs/REVIEWER_TRAINING.mdSee Quality bar and docs/REVIEWER_CHECKLIST.md.
The marketplace ships three kinds of building block:
qa-api-testing, qa-load-testing). You install only the plugins your
stack needs.great-expectations,
oauth-flow-test-author). Claude loads a skill when your request matches
its trigger; you can also ask for it by name.schema-diff-reviewer reviews a migration diff and returns a findings
table). An agent may preload one or more skills to do its work.Installed components stay dormant until a matching task comes up, so adding a plugin doesn't add noise — it adds capability that activates on demand.
/plugin marketplace add testland/qa
/plugin install <plugin-name>@testland-qa
For example:
/plugin install qa-data-quality@testland-qa
/plugin marketplace add https://github.com/testland/qa
git clone https://github.com/testland/qa ~/.claude/marketplaces/testland-qa
Before you install: plugins run inside your Claude Code session and ship agent instructions and tool wrappers. Anthropic doesn't vet marketplace contents — review a plugin's components before installing it into a sensitive project. Every component here is rating-gated (see Quality bar), but you remain in control of what runs.
New to the marketplace? Install one or two plugins for your role rather than everything — components activate on demand, so a focused set keeps things sharp.

Once a plugin is installed, its skills and agents are available to Claude
Code — invoke them by describing the task in plain language. Example with
qa-data-quality:
/plugin install qa-data-quality@testland-qa
great-expectations skill scaffolds an ExpectationSuite + Checkpoint and
wires the results into a CI gate.schema-diff-reviewer agent returns a Critical / Warning / Info findings
table covering breaking-vs-additive changes and downstream impact.Each plugin's README.md lists its skills and agents and what each one does.
