Hiero SDK TCK

A Technology Compatibility Kit (TCK) is a set of tools, documentation, and test suites used to verify whether a software implementation conforms to a specific technology standard or specification. The TCK aims to verify compliant implementations of a Hiero SDK. It will encompass tests that validate the implementation of consensus node software transactions and queries, performance and longevity testing.

Setup

First you need to clone the repository

git clone [email protected]:hashgraph/hedera-sdk-tck.git

The TCK provides ready-to-use configurations to run tests against the Hedera testnet or hedera-local-node. In near future hedera-local-node will be transfered to Hiero.

Configure usage of Hedera Testnet

  • Get a Hedera testnet account ID and private key from Hedera here
  • rename .env.testnet to .env
  • Add ECDSA account ID and private key to .env

Configure usage of local node

Configure usage of a custom network

  • Change the content of .env to fit to your network

Start a JSON-RPC server

Start only the JSON-RPC server for the SDK you want to test. The JSON-RPC server for the specified SDK will parse the JSON formatted request received by the test driver. The JSON-RPC server will execute the corresponding function or procedure associated with that method and prepare the response in JSON format to send back to the test driver.

Install and run

Install packages with npm

npm install

Run specific test file

npm run test test/account/test_accountCreateTransaction.js

Run all tests

npm run test

Reports

After running npm run test the generated HTML and JSON reports can be found in the mochawesome-report folder

Linting and Formatting

To ensure code quality and consistent styling, you can run ESLint and Prettier on the codebase.

To check for code issues, run:

npm run lint

To format the code run:

npm run format
