Prerequisites

---

Complete these steps before running your first Behave Selenium test.

1. Install the latest Python build from the official website.
2. Verify that pip is installed in your system. Install pip from official pip documentation.
3. Download the latest Selenium Client and its WebDriver bindings from the official website.
4. Install virtualenv to isolate the build from other setups and ensure tests run with the specified module versions.

pip install virtualenv

Step 1: Clone the Sample Project

---

Clone the repository and set up the environment.

git clone https://github.com/LambdaTest/Python-Behave-Selenium
cd Python-Behave-Selenium

Create a virtual environment and activate it:

virtualenv venv
source venv/bin/activate

Install the required packages:

pip install -r requirements.txt

Step 2: Set Your Credentials

---

Configure your credentials to connect to the TestMu AI Selenium Grid.

Set TestMu AI Username and Access Key in environment variables.

macOS / Linux

export LT_USERNAME="undefined"
export LT_ACCESS_KEY="undefined"

Windows

set LT_USERNAME="undefined"
set LT_ACCESS_KEY="undefined"

Step 3: Configure Your Test Capabilities

---

Define browser, version, and OS settings for your test run.

In config/config.json, update your test capabilities. This code passes browser, browser version, and operating system information, along with TestMu AI Selenium grid capabilities via the capabilities object.

[
    {
      "platformName": "Windows 10",
      "browserName": "chrome",
      "browserVersion": "latest",
      "build": "Behave Selenium Sample",
      "name": "Behave Sample Test"
    }
  ]

Capabilities Generator

Use the TestMu AI Capabilities Generator to auto-generate the capabilities class for your test requirements.

Step 4: Run the Test

---

Execute the Behave test from the command line.

behave features/test.feature 

Step 5: View Your Results

---

Check the test output on the console and the TestMu AI dashboard.

Visit the TestMu AI Automation Dashboard to view your test results. The dashboard provides:

• Text logs for each test step
• Screenshots captured during execution
• Video recordings of the full test session

Run Behave Tests Using Agent Skills

---

Use AI coding assistants to generate and run Behave tests with the TestMu AI Agent Skill.

The behave-skill is part of TestMu AI Agent Skills - structured packages that teach AI coding assistants how to write production-grade test automation.

Install the skill:

git clone https://github.com/LambdaTest/agent-skills.git
cp -r agent-skills/behave-skill .claude/skills/

# For Cursor / Copilot
cp -r agent-skills/behave-skill .cursor/skills/

tip

Install all available framework skills at once by cloning the repository directly into your tool's skills directory (e.g., .claude/skills/, .cursor/skills/).
