- **Core Improvements**:
- Refactored logging functions into a unified `logger` method for consistent output across the library.
- Enabled the `forceMemoryStorage` option in `BrainyData` initialization for improved storage flexibility in tests and specific use cases.
- **TensorFlow.js and Environment Updates**:
- Clarified the dependency structure in `README.md` to emphasize bundled dependencies and remove legacy peer dependency instructions.
- Simplified and reformatted environment detection logic for better maintainability and readability.
- **Testing Enhancements**:
- Added `tests/package-size-limit.test.ts` to monitor and validate npm package size against defined thresholds.
- Updated `tests/environment.node.test.ts` and core tests to leverage `forceMemoryStorage` for better test setup standardization.
- Improved test isolation with expanded `globalThis` utility definitions and cleanup logic.
- **Documentation**:
- Added detailed best practices for debugging and organizing tests in `DEVELOPERS.md`.
- Removed outdated installation hints from `package.json` and streamlined scripts by including `test:size` for package size validation.
**Purpose**: These changes unify core logging mechanisms, expand configurability of storage options, and improve testing reliability and coverage. Documentation and clarity are enhanced to align with updated functionality and best practices.
- **Test Improvements**:
- Introduced data-clearing steps (`.clear()`) across critical test cases for ensuring better test isolation and preventing state leakage.
- Extended support for overriding global utilities (`testUtils`) and added fallback behaviors for test vector creation.
- **Configuration Updates**:
- Added support for `distanceFunction` as an alternative to `metric` in vector operations for consistency.
- Adjusted and unified asynchronous `timeout` handling across test suites for predictability.
- **Purpose**:
- These updates improve reliability, maintainability, and clarity in test cases while ensuring compatibility across diverse test environments.
- **New Tests Added**:
- Introduced multiple test suites covering core functionalities (`core.test.ts`), vector operations (`vector-operations.test.ts`), Node.js environment (`environment.node.test.ts`), browser setup (`environment.browser.test.ts`), and TensorFlow.js-specific behaviors (`tensorflow-patch.test.ts`).
- Added performance, scalability, and error-handling tests to ensure robust validation of vector addition, search, and text embedding functionalities.
- Introduced setup utilities (`tests/setup.ts`) and standardized test utilities for creating predictable test cases.
- **Configuration**:
- Created `vitest.config.ts` for custom test configurations, including support for modern test environments (`jsdom`, `happy-dom`) and extended timeouts for asynchronous operations.
- **Validation**:
- Includes compatibility checks for TensorFlow.js imports and ensures proper handling of `TextEncoder`/`TextDecoder` in Node.js environments.
This commit significantly enhances the testing coverage and structure, ensuring Brainy functionality is robust, cross-platform, and aligned with evolving reliability standards.
