Walkthrough

The pull request introduces modifications to the Strategy contract in src/Strategy.sol, adding a governorAddress field to the StrategyState struct and updating the constructor to initialize this field. Corresponding changes are made in the test contracts TestUSDCIntegration.t.sol and TestUSDCSellRepoToken.t.sol, which include the addition of new test cases and enhancements to existing tests to validate governance-related functionalities and error handling. The overall structure and control flow of the contracts remain largely unchanged.

🐇 "In the garden of code, where changes bloom,
A governor's address dispels the gloom.
With tests that dance and functions that sing,
Our strategy grows, governance takes wing!
So hop along, let’s celebrate this feat,
In the world of contracts, our work’s complete!" 🐇

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
