Pull Request

• Closes [test] Add test for new assert in set_goal method #258
• Added tests (if necessary)
• Run tests (not succesfully)
• Run formatting
• Commented the code

Changes description

This PR adds a test for the set_goal method in contracts/src/fund.cairo. The new test validates that:

Only authorized addresses (VALID_ADDRESS_1 and VALID_ADDRESS_2) can call the set_goal method to set a new funding goal.
Unauthorized addresses are restricted from calling the method, ensuring the security and integrity of the fund goal-setting functionality.

Current output

• Before: There was no test validating the new assert logic in the set_goal method.
• After: The test suite now includes comprehensive coverage for the set_goal method, ensuring only admins can call it and that unauthorized access is properly restricted.

Time spent breakdown

• Understanding the issue and analyzing requirements: 1 hour
• Writing and debugging the test cases: 1.5 hours
• Running and validating the tests: 1 hour (this is still on work, I have an error when running the build)

Comments

This is a draft PR, I have an error when running scarb build/ snforge test related to openzeppelin and starknet dependencies, these are the logs:

Also would like to know what's the cli command for formatting the code

@renzobanegass we use scarb fmt to format the contracts
