🔀 Description of Change

Added comprehensive unit tests for the StrCompressor class in packages/utils/src/compass.ts.

Summary:

• Added unit tests for packages/utils/src/compass.ts (String Compressor utility)
• Total test files added: 1 (compass.test.ts)
• Test cases added: 35
• Coverage focus: Compression/decompression functionality, URL-safe base64 encoding, async/sync methods, edge cases

Changes:

• All tests pass successfully (35/35 passing)
• Business logic coverage improved
• Edge cases and error handling covered
• Tests follow existing patterns in packages/utils
• Type check passes with no errors

🧪 How to Test

Run the tests:

cd packages/utils && bunx vitest run --silent='passed-only' 'compass.test.ts'

Test coverage includes:

• Initialization and setup

• Synchronous compression and decompression

• Asynchronous compression and decompression

• Round-trip data integrity (sync and async)

• URL-safe base64 encoding (no +, /, or = characters)

• Cross-method compatibility (sync compress + async decompress, etc.)

• Edge cases: empty strings, Unicode characters, special characters, very long strings, JSON strings

• Compression effectiveness with various input types

• Tested locally

• Added/updated tests

• No tests needed

N/A - Test coverage only, no UI changes.

📝 Additional Information

Module Processed: packages/utils/src/compass.ts

Test Approach:

• Mocked brotli-wasm module to avoid WASM loading issues in test environment
• Used simple mock compression that preserves data integrity for testing
• Followed existing test patterns from base64.test.ts and format.test.ts
• All tests use Vitest with descriptive test names following Arrange-Act-Assert pattern
• Tests are isolated and independent

Functions tested:

• init() - Instance initialization
• compress() - Synchronous compression with URL-safe encoding
• decompress() - Synchronous decompression
• compressAsync() - Asynchronous compression
• decompressAsync() - Asynchronous decompression
• URL-safe base64 encoding/decoding (private methods tested via public API)
• Compressor singleton instance

Reviewer's Guide

Adds a new Vitest test suite covering the StrCompressor/Compressor utilities in compass.ts, including sync/async compression and decompression, URL-safe base64 behavior, edge cases, and mocking of the underlying brotli-wasm dependency.

File-Level Changes

Change	Details	Files
Introduce Vitest unit tests for the StrCompressor/Compressor API in compass.ts with a mocked brotli-wasm backend.	Create compass.test.ts exercising init, sync compress/decompress, and async compressAsync/decompressAsync flows Verify URL-safe base64 output characteristics and decoding via the public compression API Add round-trip integrity tests across sync/async combinations (e.g., sync compress + async decompress) Cover edge cases like empty strings, long strings, special/unicode characters, and JSON payloads Mock brotli-wasm to provide deterministic, lightweight compression semantics suitable for unit testing	packages/utils/src/compass.test.ts
