Embedding Mandos code in Go

Embedding in Go

Mandos steps can be embedded in Go, in order to program for more flexible behavior. One can even save dynamically generated Mandos scenarios. For a comprehensive example on how to do that, check out the delegation contract fuzzer in Elrond 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,
    ))
