Description

The test suite does not cover all failure scenarios, such as invalid tradingAccountId or withdrawals exceeding available balance.

Summary

Untested failure scenarios could result in unexpected behavior or vulnerabilities.

Vulnerability Details

• Issue: The test suite lacks coverage for failure scenarios like invalid inputs or insufficient balance.

• Example: Withdrawals exceeding the available balance or invalid tradingAccountId could cause unexpected behavior.

Impact

• Untested failure scenarios could lead to vulnerabilities or unexpected behavior in production.

Tools Used

• Manual Code Review

• Foundry/Forge

Recommendations

• Add tests for all failure scenarios, such as invalid inputs and withdrawals exceeding available balance.

function testFuzz_RevertWhen_InvalidTradingAccountId(uint128 invalidTradingAccountId) external {

vm.expectRevert("Invalid trading account");

perpsEngine.exposed_withdrawMarginUsd(invalidTradingAccountId, address(wstEth), ud60x18(1e18), ud60x18(1e18), users.naruto.account);

}
