test(oplog): add integration tests for multi-client sync and state consistency
Add Karma-based integration tests for the operation log system using real IndexedDB. Tests cover multi-client synchronization scenarios and state consistency verification. New test files: - multi-client-sync.integration.spec.ts (16 tests) - state-consistency.integration.spec.ts (17 tests) Test utilities: - TestClient helper for simulating multiple clients with independent vector clocks - Operation factory helpers for creating test operations

# Integration Test Concept for Operation Log
|
||||
|
||||
## Implementation Status: COMPLETE
|
||||
|
||||
All integration tests have been implemented and pass:
|
||||
|
||||
- **16 tests** in `multi-client-sync.integration.spec.ts`
|
||||
- **17 tests** in `state-consistency.integration.spec.ts`
|
||||
|
||||
## Recommendation Summary
|
||||
|
||||
**Use Karma-based integration tests** (not Playwright E2E) for the following reasons:
|
||||
|
||||
- Karma runs in ChromeHeadless with full IndexedDB support
|
||||
- Existing `operation-log-store.service.spec.ts` already demonstrates real IndexedDB testing
|
||||
- Service-level tests are faster and more deterministic than full E2E
|
||||
- Better control over vector clocks, clientIds, and operation timing
|
||||
|
||||
## File Structure
|
||||
|
||||
```
|
||||
src/app/core/persistence/operation-log/
|
||||
integration/
|
||||
helpers/
|
||||
test-client.helper.ts # Simulated client with its own clientId/vectorClock
|
||||
operation-factory.helper.ts # Factories for creating test operations
|
||||
state-assertions.helper.ts # Assertion helpers for state verification
|
||||
multi-client-sync.integration.spec.ts
|
||||
state-consistency.integration.spec.ts
|
||||
```
|
||||
|
||||
## Key Test Utilities
|
||||
|
||||
### TestClient Helper
|
||||
|
||||
Simulates a client with its own `clientId` and vector clock:
|
||||
|
||||
```typescript
|
||||
class TestClient {
|
||||
readonly clientId: string;
|
||||
private vectorClock: VectorClock = {};
|
||||
|
||||
createOperation(params): Operation {
|
||||
this.vectorClock[this.clientId]++;
|
||||
return { ...params, clientId: this.clientId, vectorClock: { ...this.vectorClock } };
|
||||
}
|
||||
|
||||
mergeRemoteClock(remoteClock: VectorClock): void {
|
||||
this.vectorClock = mergeVectorClocks(this.vectorClock, remoteClock);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Operation Factories
|
||||
|
||||
Extend existing `createTestOperation` pattern from `operation-log-store.service.spec.ts:12-24`:
|
||||
|
||||
```typescript
|
||||
const createTaskOperation = (client: TestClient, taskId: string, opType: OpType, payload): Operation
|
||||
const createProjectOperation = (client: TestClient, projectId: string, opType: OpType, payload): Operation
|
||||
```
|
||||
|
||||
## Test Scenarios
|
||||
|
||||
### Category 1: Multi-Client Sync (multi-client-sync.integration.spec.ts)
|
||||
|
||||
| Scenario | Description |
|
||||
| ---------------------------------------- | --------------------------------------------------------------------------------------- |
|
||||
| **1.1 Non-conflicting concurrent edits** | Client A modifies task-1, Client B modifies task-2. Both merge cleanly. |
|
||||
| **1.2 Conflict detection (same entity)** | Client A and B both edit task-1 without seeing each other's changes. Conflict detected. |
|
||||
| **1.3 Three-client vector clock merge** | A -> B -> C chain: verify merged clock contains all three clients' knowledge |
|
||||
| **1.4 Fresh client sync** | New client with empty state receives all remote operations |
|
||||
| **1.5 Stale operation rejection** | Remote sends operation with older vector clock than local - should be skipped |
|
||||
| **1.6 Duplicate operation handling** | Same operation ID received twice - only stored once |
|
||||
|
||||
### Category 2: State Consistency (state-consistency.integration.spec.ts)
|
||||
|
||||
| Scenario | Description |
|
||||
| ------------------------------------------ | ---------------------------------------------------------------------------------- |
|
||||
| **2.1 Full replay produces correct state** | Create -> Update -> Update sequence rebuilds expected state |
|
||||
| **2.2 Snapshot + tail equals full replay** | State from snapshot + tail ops equals state from full replay |
|
||||
| **2.3 Delete operation handling** | Create -> Delete sequence results in entity not existing |
|
||||
| **2.4 Operation order independence** | Same ops in different arrival order produce same final state (for non-conflicting) |
|
||||
| **2.5 Compaction preserves state** | State after compaction matches state before |
|
||||
|
||||
## Implementation Approach
|
||||
|
||||
### Phase 1: Test Infrastructure
|
||||
|
||||
1. Create `integration/` directory structure
|
||||
2. Implement `TestClient` helper class
|
||||
3. Implement operation factory helpers
|
||||
4. Add state assertion utilities
|
||||
|
||||
### Phase 2: Multi-Client Sync Tests
|
||||
|
||||
1. Two-client non-conflicting operations
|
||||
2. Two-client conflict detection
|
||||
3. Three-client vector clock convergence
|
||||
4. Fresh client sync scenario
|
||||
|
||||
### Phase 3: State Consistency Tests
|
||||
|
||||
1. Full operation replay
|
||||
2. Snapshot + tail replay equivalence
|
||||
3. Delete operation handling
|
||||
4. Compaction state preservation
|
||||
|
||||
## Test Setup Pattern
|
||||
|
||||
```typescript
|
||||
describe('Multi-Client Sync Integration', () => {
|
||||
let storeService: OperationLogStoreService;
|
||||
|
||||
beforeEach(async () => {
|
||||
TestBed.configureTestingModule({
|
||||
providers: [OperationLogStoreService, VectorClockService],
|
||||
});
|
||||
storeService = TestBed.inject(OperationLogStoreService);
|
||||
await storeService.init();
|
||||
await storeService._clearAllDataForTesting(); // Ensures test isolation
|
||||
});
|
||||
|
||||
it('should merge non-conflicting ops from two clients', async () => {
|
||||
const clientA = new TestClient('client-a');
|
||||
const clientB = new TestClient('client-b');
|
||||
|
||||
const opA = createTaskOperation(clientA, 'task-1', OpType.Create, { title: 'A' });
|
||||
const opB = createTaskOperation(clientB, 'task-2', OpType.Create, { title: 'B' });
|
||||
|
||||
await storeService.append(opA, 'local');
|
||||
await storeService.append(opB, 'remote');
|
||||
|
||||
const ops = await storeService.getOpsAfterSeq(0);
|
||||
expect(ops.length).toBe(2);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## Critical Files
|
||||
|
||||
- `src/app/core/persistence/operation-log/store/operation-log-store.service.ts` - Core storage with `_clearAllDataForTesting()`
|
||||
- `src/app/core/persistence/operation-log/store/operation-log-store.service.spec.ts` - Pattern to follow (lines 12-24 for `createTestOperation`)
|
||||
- `src/app/core/persistence/operation-log/operation.types.ts` - Operation, OpType, EntityType types
|
||||
- `src/app/pfapi/api/util/vector-clock.ts` - `compareVectorClocks`, `mergeVectorClocks` utilities
|
||||
- `src/app/core/persistence/operation-log/sync/vector-clock.service.ts` - Vector clock management
|
||||
|
||||
## Determinism Strategy
|
||||
|
||||
1. **Isolated database**: `_clearAllDataForTesting()` before each test
|
||||
2. **Controlled UUIDs**: Test helper generates predictable IDs (`test-uuid-${counter}`)
|
||||
3. **Controlled time**: Use `jasmine.clock().mockDate()` for timestamp determinism
|
||||
4. **Sequential execution**: Integration tests run sequentially (no parallel spec execution)
