## 🔬 Test Implementation Highlights
|
||||
|
||||
### Sophisticated Testing Patterns
|
||||
```python
|
||||
@pytest.fixture
|
||||
def temp_embedding_system(self):
|
||||
"""Create temporary embedding system with full cleanup."""
|
||||
temp_dir = Path(tempfile.mkdtemp())
|
||||
# ... setup complete system
|
||||
yield context_db, embedding_manager
|
||||
shutil.rmtree(temp_dir) # Guaranteed cleanup
|
||||
|
||||
def test_concurrent_embedding_generation(self, temp_embedding_system):
|
||||
"""Test thread-safe concurrent embedding operations."""
|
||||
with concurrent.futures.ThreadPoolExecutor(max_workers=3) as executor:
|
||||
futures = [executor.submit(generate_embeddings, i) for i in range(3)]
|
||||
results = [future.result() for future in futures]
|
||||
# Validate all operations completed successfully
|
||||
```
|
||||
|
||||
### Performance Validation Framework
|
||||
```python
|
||||
def test_large_scale_context_management(self, performance_system):
|
||||
"""Test managing 100+ contexts with performance metrics."""
|
||||
# Store 100 contexts in batches
|
||||
context_ids = context_db.store_contexts_batch(contexts)
|
||||
|
||||
# Build embeddings index with timing
|
||||
index_stats = embedding_manager.build_embeddings_index(batch_size=20)
|
||||
|
||||
# Validate performance benchmarks
|
||||
assert index_stats["embeddings_per_second"] > 50
|
||||
assert avg_search_time < 0.1 # Sub-100ms requirement
|
||||
```
|
||||
|
||||
### Error Isolation Testing
|
||||
```python
|
||||
def test_concurrent_error_isolation(self, error_test_system):
|
||||
"""Test that errors in one thread don't affect others."""
|
||||
# One worker intentionally fails, others succeed
|
||||
with concurrent.futures.ThreadPoolExecutor(max_workers=3) as executor:
|
||||
results = [future.result() for future in futures]
|
||||
|
||||
# Verify fault isolation
|
||||
success_count = sum(1 for r in results if r.startswith("success_"))
|
||||
assert success_count >= 1 # System remains operational
|
||||
```
|
||||
|
||||
