🚀 Load Testing Tool for JSON-RPC Servers 🔧

This load testing tool is designed to stress test JSON-RPC servers by sending a high volume of requests. It allows you to test the server's performance under different levels of concurrent connections and requests per connection.

🌟 Features

• Configurable concurrent connections and requests per connection
• Customizable JSON-RPC request body loaded from a JSON file
• Adjustable request timeout duration
• Displays results for each level of concurrent connections, including total requests, successful requests, failed requests, average response time, and average requests per second
• Exports results to a CSV file for further analysis

📚 Prerequisites

• Rust
• Tokio

📥 Installation

1. Clone this repository:

git clone https://github.com/yourusername/load-testing-tool.git

2. Change into the cloned directory:

cd load-testing-tool

3. Build the project:

cargo build --release

4. Find the compiled binary in the ./target/release folder.

🔍 Usage

1. Create a JSON file containing the JSON-RPC request body you want to use in the test. For example:

{
    "method": "eth_getLogs",
    "params": [
        {
            "fromBlock":"latest",
            "toBlock":"latest"
        }
    ],
    "id": 1,
    "jsonrpc": "2.0"
}

2. Run the load testing tool with the required arguments:

./target/release/json_rpc_load_tester [OPTIONS]

Replace [OPTIONS] with the appropriate command-line options for your test. Available options include:

• -t, --timeout: Request timeout in milliseconds (default: 15000)
• -u, --url: URL of the JSON-RPC server to test (required)
• -c, --connections: Number of concurrent connections to establish (required)
• -r, --requests: Number of requests per connection (0 for time-based test, default: 0)
• -s, --step: Connection step size for testing with varying connection counts (default: 0)
• -f, --file: Path to the file containing the JSON-RPC request (required)
• -d, --duration: Test duration in seconds

3. Analyze the results displayed in the terminal and exported to the results.csv file.
