Missing test cases for Token Methods

[has5aan]

getNextAvailableTokenID

Implementation missing.

isTokenIDAvailable

All test cases missing.

initializeToken

• Testing event emission if tokenID is not available.
• Testing event emission if tokenID is not native.

mint

• Perhaps the test case should reject if supply exceed max balance should be rephrased to be clearer.

burn

• Argument validation missing.
  No change necessary.

initializeUserAccount

• Error scenarios do not verify event emission.
  There are no events in case of error, no change necessary.

initializeEscrowAccount

• Error scenarios do not verify event emission.
  There are no events in case of error, no changes necessary.

transfer

• Should throw error and log event if recipient is not initialized however, current implementation initializes the recipient account.
  The implementation is aligned with the LIP and no change is required.

transferCrosschain

• Should throw error and log event if escrow account does not exist, however, current implementation initializes non-existent escrow account.
  Implementation is aligned with the LIP and no change is required.

supportAllTokensFromChainID

• Tests rely on calls to SupportedTokensStore, introspective testing can be improved.

removeAllTokensSupportFromChainID

• Tests rely on calls to SupportedTokensStore, introspective testing can be improved.

supportTokenID

• Tests rely on calls to SupportedTokensStore, introspective testing can be improved.

removeSupportTokenID

• Tests rely on calls to SupportedTokensStore, introspective testing can be improved.
