Introduction

In this article, we will guide you through the process of creating a node test for work package submission. This involves setting up a network with 1 builder node and 3 validator nodes, where the builder node connects to 1 of the validator nodes, and the validator nodes connect to each other. We will then make an RPC request to the builder_submitWorkPackage method to submit a work package and verify that all other validator nodes have received the work package by checking for corresponding events.

Setting Up the Network

To set up the network, we will need to create 4 nodes: 1 builder node and 3 validator nodes. Each node will have a unique address and will be connected to each other.

Builder Node

The builder node will be responsible for submitting the work package. It will connect to 1 of the validator nodes.

Node Configuration:

"name" "builder_node", "address": "0x1234567890abcdef", "type": "builder", "validator_node_address": "0x9876543210fedcba"


### **Validator Nodes**

The validator nodes will be responsible for validating the work package. They will connect to each other.

*   **Node Configuration:**

    ```bash
{
  "name": "validator_node_1",
  "address": "0x9876543210fedcba",
  "type": "validator",
  "connected_nodes": ["validator_node_2", "validator_node_3"]
}

{
  "name": "validator_node_2",
  "address": "0x7654321098dcbafe",
  "type": "validator",
  "connected_nodes": ["validator_node_1", "validator_node_3"]
}

{
  "name": "validator_node_3",
  "address": "0x543219876543210f",
  "type": "validator",
  "connected_nodes": ["validator_node_1", "validator_node_2"]
}

Creating the Network

To create the network, we will need to start each node and configure the connections between them.

Starting the Nodes

We will start each node using the following command:

node start --config <node_config>

Configuring the Connections

We will configure the connections between the nodes by setting the connected_nodes field in each node's configuration.

Verifying the Network

We will verify that the network is functioning correctly by checking that each node is connected to the other nodes.

Submitting the Work Package

To submit the work package, we will make an RPC request to the builder_submitWorkPackage method on the builder node.

RPC Request

We will make the following RPC request:

curl -X POST \
  http://builder_node:8545 \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","method":"builder_submitWorkPackage","params":["work_package_data"],"id":1}'

Verifying the Work Package

We will verify that the work package has been received by all validator nodes by checking for corresponding events.

Checking Events

We will check for events on each validator node using the following command:

curl -X POST \
  http://validator_node_1:8545 \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_getLogs","params":["0x1234567890abcdef"],"id":1}'

We will repeat this process for each validator node to verify that the work package has been received by all nodes.

Conclusion

In this article, we have guided you through the process of creating a node test for work package submission. We have set up a network with 1 builder node and 3 validator nodes, made an RPC request to the builder_submitWorkPackage method to submit a work package, and verified that all other validator nodes have received the work package by checking for corresponding events. This process can be used to test and validate the functionality of a work package submission system.

Troubleshooting

If you encounter any issues during the process, you can refer to the following troubleshooting guide:

Common Issues

Node not starting: Check that the node configuration is correct and that the node is running with the correct permissions.
Node not connected: Check that the connections between the nodes are configured correctly and that the nodes are running with the correct permissions.
Work package not received: Check that the RPC request is being sent correctly and that the work package is being received by all validator nodes.

Advanced Troubleshooting

Node logs: Check the node logs for any errors or warnings that may indicate the cause of the issue.
Network topology: Check the network topology to ensure that the nodes are connected correctly and that the connections are functioning as expected.

Introduction
