Feather Wand Agent

🚀 Feather Wand Agent

📝 Description

Feather Wand Agent is a comprehensive AI-powered toolkit for performance testing and monitoring. It integrates multiple industry-standard performance testing tools (JMeter, k6, Gatling, and Locust) into a single, unified interface, allowing users to execute and analyze performance tests through natural language interactions.

✨ Features

• 🏗️ Multi-tool agent framework supporting JMeter, k6, Gatling, and Locust
• 🤖 AI-powered conversational interface for executing performance tests
• 🧪 Unit testing utilities for ensuring agent reliability
• 📊 Performance metrics collection and analysis
• 🕵️‍♂️ Monitoring capabilities for test execution
• 🔄 Environment variable configuration for flexible deployment

🛠️ Prerequisites

• Python 3.8+
• JMeter (for JMeter tests)
• k6 (for k6 tests)
• Maven or Gradle (for Gatling tests)
• Locust (for Locust tests)

📋 Installation

1. Get a Google API key from either:

• https://console.developers.google.com/ (for Google Cloud)
• https://aistudio.google.com (for Google AI Studio)

Save this API key in the .env file, which will be created in step 3 of the installation process

# If using Gemini via Google AI Studio
GOOGLE_GENAI_USE_VERTEXAI="False"
GOOGLE_API_KEY=""

# # If using Gemini via Vertex AI on Google Cloud
# GOOGLE_CLOUD_PROJECT="your-project-id"
# GOOGLE_CLOUD_LOCATION="your-location" #e.g. us-central1
# GOOGLE_GENAI_USE_VERTEXAI="True"

1. Clone the repository:

git clone https://github.com/yourusername/perf_tools_google_agent.git
cd perf_tools_google_agent

1. Install dependencies:

pip install -r requirements.txt

1. Configure environment variables (copy .env.example to .env and modify as needed):

cp .env.example .env

🏃‍♂️ Usage

Starting the Agent

Launch the agent web interface:

adk web

This will start the agent at http://localhost:8000, where you can interact with it through the chat interface.

Supported Performance Testing Tools

JMeter

The agent can execute JMeter test plans (.jmx files) in both GUI and non-GUI modes with customizable duration and virtual user count.

Example commands:

• Run in non-GUI mode (default):

`` Run my JMeter test at /path/to/test.jmx ``

• Run in non-GUI mode (with custom settings):

`` Run my JMeter test at /path/to/test.jmx with 20 users and 300 seconds ``

• Run in GUI mode:

`` Open JMeter GUI with my test plan at /path/to/test.jmx ``

k6

The agent can execute k6 scripts (.js files) with customizable duration and virtual user count.

Example commands:

• Run with default settings (30s duration, 10 VUs):

`` Execute k6 script at /path/to/script.js ``

• Run with custom settings:

`` Run k6 test at /path/to/script.js with 50 users for 2 minutes ``

Locust

The agent can execute Locust test files (.py files) with configurable parameters.

Example commands:

• Run with default settings:

`` Run Locust test at /path/to/test.py ``

• Run with custom settings:

`` Execute Locust test at /path/to/test.py against http://example.com with 200 users at spawn rate 20 ``

Gatling

The agent can execute Gatling simulations using either Maven or Gradle as the runner.

Example commands:

• Run a Gatling simulation:

`` Run Gatling test in directory /path/to/gatling/project ``

• Run a specific simulation class:

`` Execute Gatling simulation MySimulation in directory /path/to/gatling/project ``

🔧 Configuration

The agent can be configured through environment variables in the .env file:

General Configuration

• FEATHERWAND_NAME: Name of the agent (default: featherwand_agent)
• FEATHERWAND_MODEL: AI model to use (default: gemini-2.0-flash-exp)
• FEATHERWAND_DESCRIPTION: Description of the agent

JMeter Configuration

• JMETER_BIN: Path to JMeter binary (default: jmeter)
• JMETER_JAVA_OPTS: Java options for JMeter

k6 Configuration

• K6_BIN: Path to k6 binary (default: k6)

Locust Configuration

• LOCUST_BIN: Path to Locust binary (default: locust)
• LOCUST_HOST: Default host to test (default: http://localhost:8089)
• LOCUST_USERS: Default number of users (default: 100)
• LOCUST_SPAWN_RATE: Default spawn rate (default: 10)
• LOCUST_RUNTIME: Default runtime (default: 30s)
• LOCUST_HEADLESS: Whether to run in headless mode (default: true)

Gatling Configuration

• GATLING_RUNNER: Runner to use for Gatling (default: mvn, alternative: gradle)
