In this article, our focus shifts to comprehending a flash loan attack through the process of independently re-crafting its Proof of Concept (PoC) test case, employing the Foundry project [1]. We strongly advise perusing the preceding article before delving into the technical intricacies outlined here.
Prerequisite: Understanding Flash Loan Attacks Through a Practical Example
Note: LW and GGG are equivalent in this article!

We are trying to re-write the test case for LW — FlashLoan Price Manipulation attack without looking into the source code.
Step 1: Structure
In the DeFiHackLabs repository, create a new file under the name myexp (src/test/myexp.sol). Proceed by outlining the attack template’s structure within this newly created file.
