Summary

This PR implements comprehensive unit tests for the PortfolioSnapshotter service - a critical component handling financial portfolio calculations and snapshot creation. Prior to this PR, the service had 0% test coverage despite managing high-value financial operations.

Key Achievements

  • 17 comprehensive unit tests covering all major service functionality
  • 97.78% statement coverage achieved (from 0%)
  • Critical financial calculations now thoroughly validated
  • Edge cases and error scenarios comprehensively tested

Test Coverage Areas

Core Functionality:

  • ✅ Successful portfolio snapshot creation with accurate value calculations
  • ✅ Competition validation (existence, end date checks, force flag behavior)
  • ✅ Balance filtering logic (zero vs non-zero balances)
  • ✅ Health check functionality with database connection testing

Retry Logic & Resilience:

  • ✅ Price fetching failures with exponential backoff retry logic
  • ✅ Partial price fetch success scenarios with smart retry optimization
  • ✅ Bulk agent processing with graceful error handling
  • ✅ Network failure simulation and recovery testing

Edge Cases & Precision:

  • ✅ Large portfolio values without numerical overflow
  • ✅ Mixed token types with varying decimal precision
  • ✅ Accurate financial calculations: (100 × $1.5) + (50.5 × $0.0001) + (1M × $0.000001) = $151.00505
  • ✅ Zero balance handling and filtering logic

Error Handling:

  • ✅ Missing competition scenarios
  • ✅ Empty balance states
  • ✅ Price fetch timeout and failure conditions
  • ✅ Database connectivity issues

Technical Implementation

Testing Strategy:

  • Mock-based testing with proper service dependency injection
  • Controlled system time using vi.setSystemTime() for deterministic tests
  • Fake timers with vi.advanceTimersByTimeAsync() for retry logic validation
  • Comprehensive mock data matching production database schema types

Quality Assurance:

  • All tests pass in isolation and as a suite
  • Full TypeScript type safety maintained
  • ESLint and Prettier compliance
  • Pre-commit hooks validation

Risk Reduction

This testing implementation significantly reduces risk for:

  • Financial accuracy errors in portfolio value calculations
  • Data corruption during snapshot creation processes
  • Service failures under high load or network issues
  • Integration bugs with external price feed APIs

The PortfolioSnapshotter service handles critical financial data and trading competition results. This comprehensive test coverage ensures reliability and accuracy for production financial operations.

Test plan

  • All 17 unit tests pass successfully
  • 97.78% statement coverage achieved
  • Zero Tolerance commands validated (lint, format, build, typecheck)
  • Pre-commit and pre-push hooks pass
  • No breaking changes to existing functionality
  • Service maintains full backward compatibility

@asutula i went to rebase this with claude, but it uncovered some quirky things. going to try once here to see if it over complicated it, but at the same time, might be good to tap whoever pushed changes recently to review if the test changes would have been expected

okay yeah, be sure to see the changes to apps/api/src/services/rewards.service.ts and encoding. probably expected, but want to verify again

Add 17 comprehensive unit tests for the PortfolioSnapshotter service covering:

- Successful portfolio snapshot creation with valid prices and accurate calculations
- Competition validation (exists, ended, force flag scenarios)
- Price fetching failures and retry logic with exponential backoff
- Balance filtering (zero vs non-zero balances)
- Portfolio value calculation accuracy with mixed token types
- Bulk snapshot processing for all agents with error resilience
- Health check functionality and error handling
- Edge cases: large values, partial price failures, timing scenarios

Achieves 97.78% statement coverage for critical financial portfolio calculations.

…edge cases

- Add precise financial calculation testing with decimal precision validation
- Verify zero-balance token handling in portfolio calculations
- Test database constraint handling and data integrity
- Add concurrent operation determinism verification
- Improve sequential processing validation with timestamp consistency
- Add comprehensive edge case coverage for realistic trading scenarios

These improvements ensure portfolio valuation accuracy and system resilience
under various financial conditions including high-precision crypto amounts,
worthless tokens, and database constraints.

…ge cases

Added extensive edge case testing for RewardsService including:
- Large amount overflow protection and validation
- Zero amount reward handling
- Duplicate address scenarios
- Malformed data graceful handling
- Allocator validation before allocation

Fixed three production bugs in RewardsService:
1. createLeafNode returned Hex string instead of Buffer
2. Used encodePacked instead of encodeAbiParameters affecting hash consistency
3. Type mismatch in retrieveProof when comparing leaf hashes

These bugs could have caused:
- Merkle proof generation failures
- Inconsistent hash calculations
- Blockchain allocation errors

Restored apps/api/scripts/rewards-allocate.ts and rewards-claim.ts to their
main branch state with proper kleur/colors imports. These files were
inadvertently modified during the rebase process and contained legitimate
changes from previous PRs that shouldn't have been altered.
… transaction parameter

- Add missing undefined parameter to mock expectations in TradingConstraintsService tests
- Service methods pass optional transaction parameter that becomes undefined when not provided
- This resolves CI test coverage failures

…ert-test-data.ts

- Remove custom color function stubs and use kleur/colors imports like other scripts
- Maintains consistency with kleur color library usage across all reward scripts
- Resolves TypeScript build issues with missing color implementations

Sorry this one slipped through the cracks. Still relevant and worth getting up to snuff @andrewxhill and @dtbuchholz ?

Since it's mostly net-new code, it can't hurt to see if a quick rebase and some agentic help can resolve things w/o much effort
