Sweep (fast): Write unit tests for Router contract

[stevennevins]

Details

• Test when the caller is and is not the owner of the Router
• Test the Multisend function with large transactions bundles

Checklist

• test/RouterTest.sol

• Import the Router contract, the MultiSendCallOnly library, and the necessary testing libraries.
• Define the RouterTest contract.
• Write a test function to check if the caller is the owner of the Router. This function should create a Router contract, call a function on the contract with the owner as the caller, and assert that the function call is successful.
• Write a test function to check if the caller is not the owner of the Router. This function should create a Router contract, call a function on the contract with a non-owner as the caller, and assert that the function call reverts.
• Write a test function to check the multiSend function with large transaction bundles. This function should create a Router contract, create a large transaction bundle, call the multiSend function with the transaction bundle, and assert that the function call is successful.

I have created a plan for writing the pull request. I am now working my plan and coding the required changes to address this issue. Here is the planned pull request:

Add unit tests for Router contract
sweep/add-unit-tests

Description

This PR adds unit tests for the Router contract in order to cover the scenarios mentioned in the issue. The tests check if the caller is and is not the owner of the Router, and also test the multiSend function with large transaction bundles.

Summary

• Created a new test file RouterTest.sol in the test directory.
• Imported the necessary dependencies including the Router contract, the MultiSendCallOnly library, and the testing libraries.
• Implemented a test function to check if the caller is the owner of the Router. This function creates a Router contract, calls a function on the contract with the owner as the caller, and asserts that the function call is successful.
• Implemented a test function to check if the caller is not the owner of the Router. This function creates a Router contract, calls a function on the contract with a non-owner as the caller, and asserts that the function call reverts.
• Implemented a test function to check the multiSend function with large transaction bundles. This function creates a Router contract, creates a large transaction bundle, calls the multiSend function with the transaction bundle, and asserts that the function call is successful.

Step 5: 🔁 Code Review

Here are my self-reviews of my changes at sweep/add-unit-tests.

Here is the 1st review

No changes required. The test cases in the RouterTest.sol file are well implemented and cover the necessary scenarios for the Router contract. Good job!

I finished incorporating these changes.
