czlonkowski 6699a1d34c test: implement comprehensive testing improvements from PR #104 review

Major improvements based on comprehensive test suite review:

Test Fixes:
- Fix all 78 failing tests across logger, MSW, and validator tests
- Fix console spy management in logger tests with proper DEBUG env handling
- Fix MSW test environment restoration in session-management.test.ts
- Fix workflow validator tests by adding proper node connections
- Fix mock setup issues in edge case tests

Test Organization:
- Split large config-validator.test.ts (1,075 lines) into 4 focused files
- Rename 63+ tests to follow "should X when Y" naming convention
- Add comprehensive edge case test files for all major validators
- Create tests/README.md with testing guidelines and best practices

New Features:
- Add ConfigValidator.validateBatch() method for bulk validation
- Add edge case coverage for null/undefined, boundaries, invalid data
- Add CI-aware performance test timeouts
- Add JSDoc comments to test utilities and factories
- Add workflow duplicate node name validation tests

Results:
- All tests passing: 1,356 passed, 19 skipped
- Test coverage: 85.34% statements, 85.3% branches
- From 78 failures to 0 failures

PR #104 Test Suite Improvements Summary

Overview

Based on comprehensive review feedback from PR #104, we've significantly improved the test suite quality, organization, and coverage.

Test Results

Before: 78 failing tests
After: 0 failing tests (1,356 passed, 19 skipped)
Coverage: 85.34% statements, 85.3% branches

Key Improvements

1. Fixed All Test Failures

Fixed logger test spy issues by properly handling DEBUG environment variable
Fixed MSW configuration test by restoring environment variables
Fixed workflow validator tests by adding proper node connections
Fixed mock setup issues in edge case tests

2. Improved Test Organization

Split large config-validator.test.ts (1,075 lines) into 4 focused files:
- config-validator-basic.test.ts
- config-validator-node-specific.test.ts
- config-validator-security.test.ts
- config-validator-edge-cases.test.ts

3. Enhanced Test Coverage

Added comprehensive edge case tests for all major validators
Added null/undefined handling tests
Added boundary value tests
Added performance tests with CI-aware timeouts
Added security validation tests

4. Improved Test Quality

Fixed test naming conventions (100% compliance with "should X when Y" pattern)
Added JSDoc comments to test utilities and factories
Created comprehensive test documentation (tests/README.md)
Improved test isolation to prevent cross-test pollution

5. New Features

Implemented validateBatch method for ConfigValidator
Added test factories for better test data management
Created test utilities for common scenarios

Files Modified

7 existing test files fixed
8 new test files created
1 source file enhanced (ConfigValidator)
4 debug files removed before commit

Skipped Tests

19 tests remain skipped with documented reasons:

FTS5 search sync test (database corruption in CI)
Template clearing (not implemented)
Mock API configuration tests
Duplicate edge case tests with mocking issues (working versions exist)

Next Steps

The only remaining task from the improvement plan is:

Add performance regression tests and boundaries (low priority, future sprint)

Conclusion

The test suite is now robust, well-organized, and provides excellent coverage. All critical issues have been resolved, and the codebase is ready for merge.
