Multi-Position Per User Scenarios: Fork Tests & Supporting Infrastructure
cadence/tests/fork_multiple_positions_per_user.cdcRuns against mainnet at block 142528994 using real token holders and real token identifiers (FLOW, USDF, USDC, WETH, WBTC). Contains 4 tests:
testMultiplePositionsPerUser — Creates 5 positions with different collateral types, borrows varying amounts from each, and asserts that operations on one position do not affect the health factors of others (isolation guarantee).
testPositionInteractionsSharedLiquidity — Verifies cross-position effects through the shared FLOW liquidity pool: Position A's heavy borrowing reduces available liquidity for Position B, a subsequent repayment restores it, and a crash of Position A's collateral price has zero effect on Position B's health.
testBatchLiquidations — Creates 5 positions (USDF, WETH, USDC, WBTC, FLOW) with differentiated borrow levels, crashes 4 collateral prices, then executes a single-transaction batch liquidation: 2 full liquidations (WETH, USDF) and 2 partial liquidations (USDC, WBTC). The FLOW-collateral position, whose price is unchanged, remains untouched.
testMassUnhealthyLiquidations — System-wide stress test: 100 positions across 3 collateral types (50 USDF × 10 USDF, 45 USDC × 2 USDC, 5 WBTC × 0.00009 WBTC), two risk tiers (high/moderate) per stablecoin group, simultaneous 40% price crash across all three collateral types, then batch DEX liquidation of all 100 positions in chunks of 10 to stay within computation limits. Verifies all positions recover health and protocol FLOW reserve stays positive.
cadence/transactions/flow-alp/pool-management/batch_manual_liquidation.cdc— Liquidates multiple positions in one transaction using the caller's own debt tokens as repayment.cadence/transactions/flow-alp/pool-management/batch_liquidate_via_mock_dex.cdc— Liquidates multiple positions in one transaction sourcing repayment from a pre-configured MockDexSwapper.
