Changes Description

• Bump snforge_std version to 0.27.0 After the bump, I fixed all errors caused by the upgrade of the version. This involves tests for the Fund and Donator contracts.
• Create new tests for the DonatorManager contract
  • New tests to cover all the methods in the contract
  • I have added two new methods to the contract to read the owner and the donator class hash from the storage.

Current output

Time spent breakdown

• 4 days
  • The effort involves a lot of research about how to implement the tests in the best way using snforge_std, after the research I found that the best was to update the version of this package to take advantage of the cheat codes available to set the caller address before the deployment of the contract.

Comments

• Bump snforge_std version to 0.27.0.
  • Fix and update current tests and code to match the new version.
