- **Removed Files**: - Deleted outdated statistics documentation files (`statistics.md`, `statistics-flush-solution.md`, `statistics-summary.md`) to clean up the repository and avoid confusion. - **Added Standards**: - Introduced `DOCUMENTATION_STANDARDS.md` to outline naming conventions and troubleshooting practices for more consistent and maintainable project documentation. - **Tests**: - Added a new test file `edge-cases.test.ts` to verify handling of edge cases, ensuring robust behavior against boundary values and invalid inputs. **Purpose**: Cleans up deprecated documentation while introducing concrete standards for maintaining and updating documentation. Enhances test coverage for unusual or boundary inputs, improving overall system resilience.

# Brainy Test Matrix
|
|
|
|
This document outlines a comprehensive testing strategy for the Brainy vector database, ensuring all functionality works correctly across different environments and configurations.
|
|
|
|
## Test Dimensions
|
|
|
|
The test matrix covers the following dimensions:
|
|
|
|
1. **Public Methods**: All public methods of the BrainyData class
|
|
2. **Storage Adapters**: All supported storage types
|
|
3. **Environments**: All supported runtime environments
|
|
4. **Test Types**: Happy path, error handling, edge cases, performance
|
|
|
|
## Storage Adapters
|
|
|
|
- Memory Storage
|
|
- File System Storage
|
|
- OPFS (Origin Private File System) Storage
|
|
- S3-Compatible Storage (including R2)
|
|
|
|
## Environments
|
|
|
|
- Node.js
|
|
- Browser
|
|
- Web Worker
|
|
- Worker Threads
|
|
|
|
## Test Types
|
|
|
|
- **Happy Path**: Tests with valid inputs and expected behavior
|
|
- **Error Handling**: Tests with invalid inputs, error conditions
|
|
- **Edge Cases**: Tests with boundary values, empty inputs, etc.
|
|
- **Performance**: Tests measuring execution time with various dataset sizes
|
|
|
|

## Testing Gaps to Address
|
|
|
|
1. **Error handling scenarios** for each method
|
|
- Invalid inputs
|
|
- Network failures
|
|
- Storage failures
|
|
- Concurrent operation conflicts
|
|
|
|
2. **Edge cases**
|
|
- Empty queries
|
|
- Invalid IDs
|
|
- Maximum size datasets
|
|
- Zero-length vectors
|
|
- Dimension mismatches
|
|
|
|
3. **Different storage adapters**
|
|
- Complete OPFS testing
|
|
- Complete S3 testing
|
|
- Test adapter switching/fallback
|
|
|
|
4. **Multi-environment behavior**
|
|
- Browser-specific tests
|
|
- Web Worker tests
|
|
- Worker Threads tests
|
|
|
|
5. **Read-only mode enforcement**
|
|
- Test all write operations in read-only mode
|
|
|
|
6. **Relationship operations**
|
|
- Complete testing for relate()
|
|
- Complete testing for findSimilar()
|
|
|
|
7. **Metadata handling**
|
|
- Test metadata in add/relate operations
|
|
- Test updateMetadata edge cases
|
|
|
|
8. **Large dataset operations**
|
|
- Performance with 10k+ vectors
|
|
- Memory usage optimization
|
|
|
|
9. **Concurrent operations**
|
|
- Thread safety
|
|
- Race condition handling
|
|
|
|
10. **Statistics and monitoring**
|
|
- Accuracy of statistics
|
|
- Performance impact of statistics tracking
|
|
|
|
## Implementation Plan
|
|
|
|
1. Create error handling tests for core methods
|
|
2. Create edge case tests for core methods
|
|
3. Complete storage adapter tests for OPFS and S3
|
|
4. Create environment-specific test suites
|
|
5. Implement read-only mode tests
|
|
6. Complete relationship operation tests
|
|
7. Create metadata handling tests
|
|
8. Implement performance tests with various dataset sizes
