Exceptions

Exception types are represented as a JSON string in the test fixtures.

The exception converted into a string is composed of the exception type name, followed by a period, followed by the specific exception name.

For example, the exception INSUFFICIENT_ACCOUNT_FUNDS of type TransactionException is represented as "TransactionException.INSUFFICIENT_ACCOUNT_FUNDS".

The JSON string can contain multiple exception types, separated by the | character, denoting that the transaction or block can throw either one of the exceptions.

TransactionException

Bases: ExceptionBase

Exception raised when a transaction is invalid, and thus cannot be executed.

If a transaction with any of these exceptions is included in a block, the block is invalid.
