Verifying a test

The owner of a test can choose to 'verify it' by providing the open answer hashes needed to solve it directly on-chain. We can do so by calling the following function inside the TestCreator.sol smart contract:

function verifyTestAnswers(
    uint256 testId,
    uint256[] memory answerHashes
)

And providing it the answerHashes (open answer hashes) for the given testId. Bear in mind that, once set, these answer hashes cannot be overwritten.

We assume that the credential issuer will provide the correct answerHashes necessary to solve their credential. Even though the smart contract could define a way to verify this, it is after all in the credential issuer best interest to give tests that are solvable.
