Integration

Scripting

#!/bin/bash
# Example script using selenium

if ! command -v selenium &> /dev/null; then
    echo "selenium is not installed"
    exit 1
fi

if selenium run; then
    echo "Success"
else
    echo "Failed"
    exit 1
fi

API Integration

import subprocess
import json

def run_selenium(command):
    try:
        result = subprocess.run(['selenium'] + command.split(),
                              capture_output=True, text=True)
        return result.stdout
    except Exception as e:
        print(f"Error: \\\\{e\\\\}")
        return None

Environment Variables
