Lbamm Test

LBAMM Foundry Test Generator

Generate Foundry test suites following LBAMM test patterns and conventions.

Project Setup

Before generating code, check the user's project is configured:

1. Foundry: foundry.toml must exist. If not: forge init
2. LBAMM Core: lib/lbamm-core/ must exist. If not: forge install limitbreakinc/lbamm-core
3. Remappings: remappings.txt needs @limitbreak/lbamm-core/=lib/lbamm-core/. Append if missing -- do not overwrite existing entries.
4. Local testing: LBAMM is in audit and not yet on public networks. For local testing, use lbamm-examples -- see lbamm-protocol/references/local-dev.md. Generated scripts should read addresses from environment variables (vm.envAddress) so they work with the local Anvil deployment.

Instructions

1. Read the contract under test (if referenced in $ARGUMENTS)

2. Resolve ambiguities before generating -- if $ARGUMENTS doesn't reference a specific contract or file to test, or it's unclear which aspects to cover (happy paths, reverts, fees, access control), ask in a single message. If clear, proceed.

3. Select the correct base test class:

   • LBAMMCoreBaseTest -- For testing core AMM operations, token settings, fee management
   • LBAMMCorePoolBaseTest -- For testing pool-specific operations (swaps, liquidity, fees) -- extends LBAMMCoreBaseTest with pool operation helpers
   • For hooks-and-handlers tests: extend one of the above or create a custom base

4. Generate setUp() with:

   • Deterministic CREATE2 deployment for pool types (using salts from TestConstants.t.sol)
   • Mock token deployment (ERC20Mock at well-known addresses via vm.etch)
   • Role server and transfer validator setup
   • Pool creation with appropriate parameters
   • Token approvals and initial balances

5. Generate test cases for:

   • Happy paths (successful operations)
   • Edge cases (zero amounts, max values, boundary conditions)
   • Revert conditions (with vm.expectRevert(SelectorName.selector))
   • Fee verification (protocol fees, hook fees, exchange fees)

6. Use established helpers:

   • _executeSingleSwap(), _executeMultiSwap(), _executeDirectSwap()
   • _executeAddLiquidity(), _executeRemoveLiquidity(), _executeCollectFees()
   • _createPool(), _createPoolWithAddLiquidity()
   • _mintAndApprove(), _dealDepositApproveNative()
   • _setTokenSettings(), _setProtocolFees()
   • _packSettings() for building token flag bitmasks
