testing

testing is a skill for Claude Code from vmkteam/claude-plugins. It costs 93 tokens per session (2,684 once invoked), scanned A, original, MIT.

A set of testing rules for Go services, including how to structure subtests, repeated test cases, database tests, and fast test runs. It recommends testing real transports and databases instead of using simulated replacements.

In plain words
What is it for?
Use it when creating or updating Go tests, configuring test startup, running database tests, or defining short test commands.
Why use it?
It gives a consistent way to write and run tests, while separating database-dependent tests from quicker checks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Testing — паттерны тестирования

Паттерны тестирования для vmkteam Go-сервисов.

Принципы

  • Фреймворк — как в соседних *_test.go пакета: стили в одном пакете не смешивай. В новых пакетах и проектах — t.Run + testify/assert + testify/require, table-driven для множественных кейсов. Существующие goconvey-тесты не переписывай ради переписывания
  • Без моков — тестируем реальный транспорт, реальную базу
  • TestDB префикс — тесты с БД именуются TestDB*
  • test-short пропускает DB-тесты через regex Test[^D][^B]
  • Покрытие — happy path и ошибочные пути: пустой ввод, слишком длинный, граничные значения, отсутствующая запись, повторный вызов. Непокрытый ошибочный путь — дыра
  • Create проверяет поля базы — не только id и эхо входа, но и то, что заполняет база: createdAt, значения по умолчанию, вычисляемые колонки (сгенерированный Add их не возвращает, см. /mfd)
  • Инварианты — если в задаче есть числовой или глобальный инвариант («≤ N», «суммарно», «во всех ветках»), первым пиши тест на худший случай (максимум полей, длины, количества) и убедись, что он падает на старом коде

Makefile targets

# Все тесты (включая DB)
test:
	@PGDATABASE=$(TEST_PGDATABASE) go test -count=1 $(GOFLAGS) -coverprofile=coverage.txt -covermode count $(PKG)

# Быстрые тесты (без DB) — пропускает TestDB*
test-short:
	@go test $(GOFLAGS) -v -test.short -test.run="Test[^D][^B]" -coverprofile=coverage.txt -covermode count $(PKG)

# Пересоздать тестовую БД
db-test:
	@dropdb --if-exists $(TEST_PGDATABASE)
	@createdb -E UTF-8 $(TEST_PGDATABASE)
	@psql -f docs/schema.sql $(TEST_PGDATABASE)

Канонический стиль (t.Run + testify)

import (
    "testing"

    "github.com/stretchr/testify/assert"
    "github.com/stretchr/testify/require"
)

func TestDBUserService(t *testing.T) {
    ctx := t.Context()
    srv := NewUserService(testDB)

    t.Run("CRUD", func(t *testing.T) {
        in := User{
            Login:    fmt.Sprintf("ivan_%d", time.Now().Unix()),
            Password: "pwd",
            StatusID: db.StatusEnabled,
        }

        out, err := srv.Add(ctx, in)
        require.NoError(t, err)
        require.NotNil(t, out)
        assert.Greater(t, out.ID, 0)

        got, err := srv.GetByID(ctx, out.ID)
        require.NoError(t, err)
        assert.Equal(t, in.Login, got.Login)

        got.Login = "updated"
        ok, err := srv.Update(ctx, *got)
        require.NoError(t, err)
        assert.True(t, ok)

        ok, err = srv.Delete(ctx, out.ID)
        require.NoError(t, err)
        assert.True(t, ok)
    })

    t.Run("empty login is rejected", func(t *testing.T) {
        _, err := srv.Add(ctx, User{Login: "", Password: "pwd", StatusID: db.StatusEnabled})
        require.Error(t, err)
    })
}

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

testing is a skill published in the GitHub repository vmkteam/claude-plugins (7 stars, last pushed 6d ago), licensed MIT. It adds 93 tokens to every session and 2,684 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
