This framework generates random schemas, data, and queries to ensure TanStack DB produces results that match SQLite's output. + +## Architecture + +### Core Components + +#### 1. **Generators** (`generators/`) + +- **`schema-generator.ts`**: Generates random database schemas with tables, columns, and relationships +- **`row-generator.ts`**: Creates test data that conforms to the generated schemas +- **`query-generator.ts`**: Generates random SQL queries using TanStack DB's query builder +- **`mutation-generator.ts`**: Creates random insert, update, and delete operations + +#### 2. **SQL Translation** (`sql/`) + +- **`ast-to-sql.ts`**: Converts TanStack DB's Intermediate Representation (IR) to SQLite SQL +- **`sqlite-oracle.ts`**: Provides a real SQLite database instance for comparison + +#### 3. **Test Harness** (`harness/`) + +- **`property-test-harness.ts`**: Main orchestrator that runs test sequences and validates properties + +#### 4. **Utilities** (`utils/`) + +- **`incremental-checker.ts`**: Validates invariants and compares TanStack DB vs SQLite results +- **`normalizer.ts`**: Normalizes data for comparison (handles type differences, ordering, etc.) +- **`functional-to-structural.ts`**: Converts functional expressions to structural IR + +### Test Types + +#### 1. **Property-Based Tests** (`property-based-tests.test.ts`) + +Tests the core properties that must hold true for the query engine: + +- **Property 1: Snapshot Equality**: TanStack DB results match SQLite oracle +- **Property 2: Incremental Convergence**: Query results remain consistent under mutations +- **Property 3: Optimistic Transaction Visibility**: Transaction state is properly managed +- **Property 4: Row Count Sanity**: Row counts are consistent between systems +- **Property 5: Query Feature Coverage**: All query features work correctly +- **Property 6: Data Type Handling**: All data types are handled properly +- **Property 7: Error Handling**: Edge cases are handled gracefully + +#### 2. **Quick Test Suite** (`quick-test-suite.test.ts`) + +Rapid validation tests for the PBT framework itself: + +- Schema generation validation +- Row generation validation +- Query generation validation +- SQL translation validation +- Basic property validation + +#### 3. **Comprehensive SQL Coverage** (`comprehensive-sql-coverage.test.ts`) + +Systematic testing of SQL translation capabilities: + +- All comparison operators (`eq`, `gt`, `gte`, `lt`, `lte`, `in`, `like`, `ilike`) +- Logical operators (`and`, `or`, `not`) +- Functions (`upper`, `lower`, `length`, `concat`, `coalesce`, `add`) +- Aggregates (`count`, `avg`, `sum`, `min`, `max`) +- `DISTINCT` queries +- Subqueries in `FROM` clauses +- `ORDER BY`, `GROUP BY`, `LIMIT`, `OFFSET` + +#### 4. **Framework Unit Tests** (`framework-unit-tests.test.ts`) + +Unit tests for individual PBT components: + +- Generator validation +- SQL translation validation +- Normalizer validation +- Oracle validation + +#### 5. **Integration Tests** + +- **`tanstack-sqlite-comparison.test.ts`**: Direct comparison of TanStack DB vs SQLite +- **`query-builder-ir-extraction.test.ts`**: Tests IR extraction from query builder +- **`ir-to-sql-translation.test.ts`**: Tests IR to SQL translation + +## How It Works + +### 1. **Test Sequence Generation** + +```typescript +// Generate a random schema +const schema = generateSchema(config) + +// Generate test data +const rows = generateRowsForTable(table, config) + +// Generate test commands (mutations + queries) +const commands = generateCompleteTestSequence(schema, config) +``` + +### 2. **Test Execution** + +```typescript +// Initialize test state +const state = { + schema, + collections: new Map(), // TanStack DB collections + sqliteDb: new SQLiteOracle(), // SQLite oracle + activeQueries: new Map(), + // ... +} + +// Execute commands +for (const command of commands) { + await checker.executeCommand(command) +} +``` + +### 3. **Property Validation** + +```typescript +// Check snapshot equality +const snapshotCheck = await checker.checkSnapshotEquality() + +// Check incremental convergence +const convergenceCheck = await checker.checkIncrementalConvergence() + +// Check transaction visibility +const visibilityCheck = await checker.checkOptimisticVisibility() + +// Check row count sanity +const rowCountCheck = await checker.checkRowCountSanity() +``` + +### 4. **Result Comparison** + +```typescript +// Compare TanStack DB vs SQLite results +const comparison = normalizer.compareRowSets(tanstackResult, sqliteResult) + +// Handle ordering differences +if (hasOrderBy) { + // Results must match exactly including order + expect(comparison.equal).toBe(true) +} else { + // Results can be in different order + const sortedComparison = normalizer.compareRowSets( + sortedTanstack, + sortedSqlite + ) + expect(sortedComparison.equal).toBe(true) +} +``` + +## Key Features + +### **Real SQLite Oracle** + +Uses `better-sqlite3` for deterministic comparison against TanStack DB's results. + +### **Comprehensive SQL Translation** + +Converts TanStack DB's IR to SQLite-compatible SQL, supporting: + +- All comparison operators +- Logical operators +- Functions and aggregates +- Subqueries and joins +- Ordering and grouping + +### **Robust Data Normalization** + +Handles type differences, ordering, and edge cases: + +- Number precision differences +- Boolean vs integer representations +- Object/array serialization +- Null handling + +### **Error Handling** + +Gracefully handles expected failures: + +- Non-existent rows/columns +- Invalid SQL syntax +- Schema generation edge cases + +### **Reproducibility** + +- Deterministic seeds for reproducible failures +- Detailed error reporting with failing command sequences +- Regression test fixtures + +## Running Tests + +### Quick Tests + +```bash +pnpm test:property:quick +``` + +### Full Property Tests + +```bash +pnpm test:property +``` + +### Coverage Report + +```bash +pnpm test:property:coverage +``` + +### Example Usage + +```bash +pnpm test:property:example +``` + +## Configuration + +The framework is configurable via `GeneratorConfig`: + +```typescript +interface GeneratorConfig { + maxTables: number // Maximum tables per schema + maxColumns: number // Maximum columns per table + minRows?: number // Minimum rows per table + maxRows?: number // Maximum rows per table + maxRowsPerTable: number // Maximum rows per table + minCommands?: number // Minimum commands per test + maxCommands: number // Maximum commands per test + maxQueries: number // Maximum queries per test + floatTolerance: number // Float comparison tolerance +} +``` + +## Validation Properties + +### **Snapshot Equality** + +Ensures that TanStack DB query results exactly match SQLite oracle results. + +### **Incremental Convergence** + +Verifies that query results remain consistent as the database state changes through mutations. + +### **Optimistic Transaction Visibility** + +Validates that transaction state is properly managed and visible to queries. + +### **Row Count Sanity** + +Confirms that row counts are consistent between TanStack DB and SQLite across all tables. + +### **Query Feature Coverage** + +Tests that all query features (WHERE, JOIN, ORDER BY, etc.) work correctly. + +### **Data Type Handling** + +Ensures all data types (strings, numbers, booleans, objects, arrays) are handled properly. + +### **Error Handling** + +Validates that edge cases and error conditions are handled gracefully. + +## Benefits + +1. **Comprehensive Coverage**: Tests a wide range of scenarios through random generation +2. **Oracle Validation**: Uses SQLite as a trusted reference implementation +3. **Regression Detection**: Catches regressions through reproducible test sequences +4. **Edge Case Discovery**: Finds edge cases that manual testing might miss +5. **Confidence Building**: Provides confidence in query engine correctness + +## Future Enhancements + +- **Performance Testing**: Add performance property validation +- **Concurrency Testing**: Test concurrent query execution +- **Migration Testing**: Validate schema migration scenarios +- **Integration Testing**: Test with real application scenarios diff --git
