RPC Tests

A mini framework for testing RPC calls is provided to make it as easy as possible to test the calls you rely on. See RoundTripRpcRequestTests for example usage.

• If you plan to add several tests, create a new class to avoid merge conflicts.
• If you feel there is already enough response test coverage, you can skip it by only providing the expected request

JSON. * See ParseRpcResponseTests for additional response parsing tests.

• If the response JSON is large, add it to the resource directory as a

JSON file. * If the JSON file is larger than 1MB, apply zip compression to it. * If it is large because it is a collection of items, consider trimming the list down to at least two items.

Capture Request JSON

• Start a test with the desired call, the test will fail with the difference between the expected and actual requests.

@Test
void getHealth() {
  registerRequest("{}");
  rpcClient.getHealth().join();
}

SEVERE: Expected request body does not match the actual. Note: The JSON RPC "id" does not matter.
 - expected: {}
 - actual:   {"jsonrpc":"2.0","id":123,"method":"getHealth"}

• Or, enable debug logging by using a logging.properties file and pass it to the VM via:

-Djava.util.logging.config.file=logging.properties

Capture Response JSON

var rpcClient = SolanaRpcClient.build().testResponse((_, body) -> {
  final var json = new String(body);
  System.out.println(json); // Write to a file if large.
  return true;
}).createClient();

Validation

Reference the official Solana RPC documentation to verify that the expected parameters are passed in the request, and if applicable, all the desired response data is parsed correctly.
