Multi-Position Scenarios Testing

[UlyanaAndrukhiv]

Context

Implement comprehensive test coverage for users managing multiple concurrent positions, batch operations, and system-wide stress scenarios to ensure position isolation, correct aggregation logic, and protocol resilience under extreme load.

Current test coverage focuses primarily on single-position workflows. Production systems will have users managing multiple positions simultaneously, this gap represents a critical risk for protocol security and user experience.

Missing Test Coverage

• Multiple Positions Per User

  • User creates 5+ positions with different collateral types
  • Each position has different health factors
  • Operations on one position should not affect others (isolation)
  • Aggregated health calculations across all user positions

• Position Interactions

  • Multiple positions in same pool
  • Competing for limited deposit capacity
  • Shared liquidity pools
  • Cross-position collateral effects

• Batch Liquidations

  • Multiple unhealthy positions liquidated in same transaction
  • Gas cost optimization for batch operations
  • Priority ordering for liquidations
  • Partial liquidation of multiple positions

• System-Wide Stress

  • 100+ positions become unhealthy simultaneously
  • Limited liquidator capacity
  • Protocol solvency under extreme conditions
  • Recovery mechanisms

Recommended Tests

Test: User creates 3 positions with FLOW, USDC, and WETH collateral
Test: Liquidate 5 positions in single transaction
Test: Position A health affects Position B liquidity
Test: 100 positions become unhealthy, liquidate in order
