Testing in Go

At some point in the past we built some testing solutions in Go. They were never very popular, but are worth mentioning.

This page is currently a stub. If there is interest in this type of testing, we will expand it further.

Embedding in Go

Scenario steps can be embedded in Go, in order to program for more flexible behavior. One can even save dynamically generated scenarios. For a comprehensive example on how to do that, check out the delegation contract fuzzer in MultiversX VM or the DNS contract deployment scenario test generator. Just a snippet from the fuzzer:

_,
  (err = pfe.executeTxStep(
    fmt.Sprintf(
      `
    {
        "step": "scDeploy",
        "txId": "-deploy-",
        "tx": {
            "from": "''%s",
            "value": "0",
            "contractCode": "file:delegation.wasm",
            "arguments": [
                "''%s",
                "%d",
                "%d",
                "%d"
            ],
            "gasLimit": "100,000",
            "gasPrice": "0"
        },
        "expect": {
            "out": [],
            "status": "",
            "logs": [],
            "gas": "*",
            "refund": "*"
        }
    }`,
      string(pfe.ownerAddress),
      string(pfe.auctionMockAddress),
      args.serviceFee,
      args.numBlocksBeforeForceUnstake,
      args.numBlocksBeforeUnbond
    )
  ));
