refactor(tests): add integration test infrastructure and review fixes

[zbigniewsobiecki]

Summary

• Integration test infrastructure: Vitest workspace with separate unit/integration projects, docker-compose.test.yml for isolated Postgres, shared helpers (factories, mock DB, mock personas), and a full credential repository integration test suite including encryption round-trip coverage
• Unit test cleanup: Remove redundant mock boilerplate (vi.mock, beforeEach resets) across 100+ test files by centralizing into workspace setup files and shared helpers (~800 lines removed)
• Review fixes: OS-aware psql in ensure-services.sh (macOS compat), explicit DATABASE_URL in setup.sh migrations, build step in CI integration job, container_name in docker-compose, documentation comments in test setup files
• Lint fix: Extract buildProgressMonitorConfig() from executeWithBackend() to resolve pre-existing cognitive complexity warning (21 → under 15)

Changes

New files

File	Purpose
vitest.workspace.ts	Workspace config separating unit and integration test projects
docker-compose.test.yml	Ephemeral Postgres 16 container for integration tests (port 5433, tmpfs)
tests/integration/setup.ts	Integration test global setup (migrations, DB lifecycle)
tests/integration/helpers/db.ts	DB helpers (runMigrations, truncateAll, closeTestDb)
tests/integration/helpers/seed.ts	Seed factories for org, project, credential, integration
tests/integration/db/credentialsRepository.test.ts	Full CRUD + resolution + encryption integration tests
tests/helpers/factories.ts	Shared mock factories for unit tests
tests/helpers/mockDb.ts	Centralized DB mock setup
tests/helpers/mockPersonas.ts	Centralized personas mock setup

Modified files

Area	Files	Change
.cascade/	ensure-services.sh, setup.sh, env	OS-aware psql, explicit migration URLs, TEST_DATABASE_URL
.github/workflows/ci.yml	CI config	Integration test job + build step
src/backends/adapter.ts	Backend adapter	Extract progress monitor config to reduce complexity
vitest.config.ts	Test config	Add unstubEnvs, adjust for workspace
package.json	Scripts	Add test:integration script
tests/unit/**	100+ test files	Remove redundant mock boilerplate
web/src/components/projects/pm-wizard.tsx	PM wizard	Remove unused imports

Test plan

• npm test — 187 test files, 3198 tests pass
• npm run typecheck — clean
• npm run lint — clean (pre-existing warning resolved)
• CI: lint-and-test job passes
• CI: integration-tests job passes (requires Postgres service container)
• CI: docker-build-check passes

🔍 Code Review Update (1 min)

I've been reviewing the provided PR, focusing on understanding the changes and ensuring best practices. I've confirmed that pm-wizard.tsx was mentioned in the PR description but not actually changed, and I've verified that the trigger tests are correctly utilizing helper factories. I've also confirmed that vi.stubEnv is being handled correctly in the integration tests due to unstubEnvs: true in the Vitest config, and that the DATABASE_URL is properly handled for lazy-initialized DB clients.

Summary

LGTM — well-structured addition of integration test infrastructure with clean test boilerplate reduction. The changes are consistent and correct.

What's good

The clearMocks: true and unstubEnvs: true in vitest.config.ts make the removal of ~100 vi.clearAllMocks() / vi.unstubAllEnvs() calls safe — Vitest handles this automatically in beforeEach/afterEach. The configCache import change in tests/setup.ts avoids a real module-loading side-effect (pulling in DB client during unit tests). The integration test infrastructure (workspace separation, Docker Compose, seed helpers, truncation strategy) follows solid patterns.

Minor observations (non-blocking)

1. PR description lists pm-wizard.tsx as modified (removing unused imports) but it's not in the diff. No code issue — just a stale description entry.

2. Integration tests only run on push (if: github.event_name == 'push'). This is a reasonable choice to avoid service containers on every PR, but means this PR's integration tests won't be validated until merge to dev. Worth noting for the merge checklist.

3. buildProgressMonitorConfig extraction (adapter.ts) — clean refactoring to reduce cognitive complexity. The function signature and spread behavior are preserved exactly.

No blocking issues, no security concerns, no correctness bugs found.

Request Addressed

What was asked

Make the integration tests run on PRs.

Changes Made

• Removed if: github.event_name == 'push' from the integration-tests job in .github/workflows/ci.yml
• The job now runs on both push (to main/dev) and pull_request events

Verification

• All 3198 unit tests passing
• TypeScript typecheck clean
• Lint clean

[aaight]

Done — removed the if: github.event_name == 'push' guard from the integration-tests job so it now runs on both pushes and PRs. The Postgres service container will spin up for PR checks too.
