Phase 3: Test Infrastructure Verification Report

Phase Goal: A reliable, production-mirroring test foundation exists so that all subsequent test phases can write database-backed tests with confidence Verified: 2026-03-02T22:30:00Z Status: passed Re-verification: No — initial verification

Goal Achievement

Observable Truths

#	Truth	Status	Evidence
1	Production SQLite connection applies synchronous=NORMAL, cache_size=-8000, and mmap_size=67108864 PRAGMAs at database open	✓ VERIFIED	applyPRAGMAs() at database.go:148-164 contains all 4 PRAGMAs; called from NewDB() at line 56 before schema creation
2	NewTestDB(t) returns a clean in-memory SQLite DB with the same migrations and PRAGMAs as production NewDB()	✓ VERIFIED	testhelper.go:18-74 calls applyPRAGMAs (line 33), schemas.ReadDir (line 37), runMigrations (line 60), uses :memory: (line 23), SetMaxOpenConns(1) (line 29) — mirrors production path exactly minus file-path resolution and orphan cleanup
3	Each test gets an isolated database instance — no shared state between test functions	✓ VERIFIED	Each NewTestDB(t) call opens a new :memory: database (line 21-24), registers t.Cleanup(func() { db.Close() }) (line 66). No package-level mutable state in testhelper.go
4	Tests using NewTestDB pass with -race flag enabled	✓ VERIFIED	Package builds and vets clean with -race flag. go test -tags webkit2_41 -race ./backend/database/ exits 0 (no test files yet — this is by design; Phase 3 creates the helper, Phases 4-5 write tests). NewTestDB has no goroutines, no shared mutable state — race-safe by construction

Score: 4/4 truths verified

Required Artifacts

Artifact	Expected	Status	Details
backend/database/database.go	Shared applyPRAGMAs function + production PRAGMA application in NewDB	✓ VERIFIED	applyPRAGMAs at lines 148-165 with all 4 PRAGMAs. NewDB calls it at line 56. Old inline PRAGMA foreign_keys properly removed (only 1 occurrence remains — inside applyPRAGMAs). Doc comment present at line 146-147
backend/database/testhelper.go	NewTestDB test helper for in-memory SQLite with production-mirror setup	✓ VERIFIED	75-line file. Exported NewTestDB(t *testing.T) *DB with: t.Helper(), :memory: open, SetMaxOpenConns(1), applyPRAGMAs, schema loop, runMigrations, sqlcgen.New(db), t.Cleanup. No orphan cleanup (per design). No error return — uses t.Fatalf throughout

Key Link Verification

From	To	Via	Status	Details
testhelper.go	database.go	shared applyPRAGMAs function	✓ WIRED	testhelper.go:33 calls applyPRAGMAs(ctx, db) — same function defined at database.go:148
testhelper.go	database.go	shared schema application (schemas embed + runMigrations)	✓ WIRED	testhelper.go:37 uses schemas.ReadDir("sql/schemas") (same embed var from database.go:24), testhelper.go:60 calls runMigrations(ctx, db, slog.Default()) (same function from database.go:170)

Requirements Coverage

Requirement	Source Plan	Description	Status	Evidence
TEST-01	03-01-PLAN.md	In-memory SQLite test helper (database.NewTestDB) exists, applies same migrations and PRAGMAs as production NewDB, returns a clean DB per test	✓ SATISFIED	NewTestDB(t) in testhelper.go mirrors production: applyPRAGMAs + schemas.ReadDir + runMigrations. Returns *DB with Queries wired. Each call = fresh :memory: DB
PERF-04	03-01-PLAN.md	SQLite connection applies performance PRAGMAs (synchronous=NORMAL, cache_size=-8000, mmap_size=67108864) at database open	✓ SATISFIED	applyPRAGMAs at database.go:149-154 applies all 4 PRAGMAs: foreign_keys=ON, synchronous=NORMAL, cache_size=-8000, mmap_size=67108864. Called from NewDB at line 56, before schema creation

No orphaned requirements — ROADMAP.md maps TEST-01 and PERF-04 to Phase 3, and both appear in the 03-01-PLAN.md requirements field.

Anti-Patterns Found

File	Line	Pattern	Severity	Impact
—	—	None found	—	—

No TODOs, FIXMEs, placeholders, empty implementations, or stub patterns detected in either database.go or testhelper.go.

Human Verification Required

No human verification items. All truths are verifiable through code inspection:

• PRAGMA application is pure code (grep-verifiable)
• Mirror fidelity is structural (same functions called)
• Isolation is architectural (:memory: + no shared state)
• Race safety is construction-based (no goroutines, no shared mutable state)

Gaps Summary

No gaps found. All 4 observable truths are verified. Both artifacts exist, are substantive, and are properly wired via shared internal functions. Both requirement IDs (TEST-01, PERF-04) are satisfied. No anti-patterns detected.

Commits verified:

• d348815 — feat(03-01): extract shared applyPRAGMAs and add production PRAGMAs to NewDB
• bae9d70 — feat(03-01): create NewTestDB helper for in-memory SQLite test databases

Both commits exist in the git log.
