Asserter

GoDoc

The Asserter package is used to validate the correctness of Rosetta types. It is important to note that this validation only ensures that required fields are populated, fields are in the correct format, and transaction operations only contain types and statuses specified in the /network/status endpoint.

If you want more intensive validation, try running the Rosetta CLI.

Installation

go get github.com/coinbase/rosetta-sdk-go/asserter

Validation file

Asserter package also allows you to specify a validation file which can be used to have a stricter validation against your implementation.

A simple validation files looks like this. Let's break it down and see what it means

"enabled": true

Specifies if we want to enable this validation or not.

"chain_type": "account",

Specify the chain type. Supported types are account and utxo. Right now we only support account based implementation for validation using this file.

"payment": {
  "name": "PAYMENT",
  "operation": {
    "count": 2,
    "should_balance": true
  }
},

This first validation will validate payment or transaction type. The payment object is defined below

  • name: The string used for defining a payment or transaction
  • operation:
    • count: Count of payment operations (defined by name) which should be present in the transaction. If the number is -1, then we won't validate the count
    • should_balance: If the sum total of the amount defined in the all the operations (defined by name) in a particular transaction should add up to 0 or not. This is really helpful to validate a debit and credit operation in the implementation
"fee": {
  "name": "FEE",
  "operation": {
    "count": 1,
    "should_balance": false
  }
}

Similar to payment type we have fee type. The fields here have the same usage as above.

NOTE

Right now we only support payment and fee operation type with count and total balance match. We will keep adding more validations to it.
