# Complete Setup Guide - Load Testing Environment

## 📦 What's Included

### 1. `requirements.txt`
Complete list of Python dependencies needed for load testing:
- pytest (testing framework)
- selenium (browser automation)
- webdriver-manager (automatic ChromeDriver management)
- And more...

### 2. `setup_load_test_environment.sh`
World-class setup script that:
- ✅ Checks Python version (3.8+)
- ✅ Creates virtual environment
- ✅ Installs all dependencies
- ✅ Validates Chrome/ChromeDriver
- ✅ Verifies function signature
- ✅ Creates necessary directories
- ✅ Provides clear feedback and next steps

## 🚀 Quick Start

### For Fresh Systems

```bash
# 1. Navigate to project
cd /home/tech4biz/work/CP_Front_Automation_Test

# 2. Run setup script
./setup_load_test_environment.sh

# 3. Activate virtual environment (if not auto-activated)
source venv/bin/activate

# 4. Validate setup
python3 tests/load_tests/validate_function_signature.py

# 5. Run your first test
python3 tests/load_tests/test_generic_load_assessments.py \
    --csv your_students.csv \
    --start 0 --end 1 \
    --workers 1 --headless
```

## 📋 What the Setup Script Does

### Step-by-Step Process

1. **Python Check** - Verifies Python 3.8+ is installed
2. **pip Check** - Ensures pip is available
3. **Virtual Environment** - Creates/validates venv
4. **Dependencies** - Installs all packages from requirements.txt
5. **Chrome Check** - Verifies Chrome browser (or notes auto-install)
6. **ChromeDriver** - Notes that webdriver-manager handles it automatically
7. **Function Validation** - Validates load test function signature
8. **Project Structure** - Verifies all required files/directories exist
9. **Reports Directory** - Creates reports/load_tests directory
10. **Final Verification** - Tests Python imports

### Output Example

```
================================================================================
🚀 World-Class Load Test Environment Setup
================================================================================

Step 1: Checking Python version...
✅ Python 3.10.12 found (>= 3.8 required)

Step 2: Checking pip...
✅ pip3 found

Step 3: Setting up virtual environment...
✅ Virtual environment created

Step 4: Activating virtual environment...
✅ Virtual environment activated

Step 5: Upgrading pip...
✅ pip upgraded to latest version

Step 6: Installing Python dependencies...
✅ All Python dependencies installed

Step 7: Checking Chrome browser...
✅ Chrome found: Google Chrome 120.0.6099.109

Step 8: Checking ChromeDriver...
⚠️  ChromeDriver not found in PATH
ℹ️  webdriver-manager will automatically download and manage ChromeDriver
✅ ChromeDriver will be handled automatically

Step 9: Validating load test function signature...
✅ Function signature validation passed

Step 10: Validating project structure...
✅ Directory exists: pages
✅ Directory exists: utils
✅ Directory exists: tests/load_tests
✅ Directory exists: config
✅ File exists: tests/load_tests/test_generic_load_assessments.py
✅ File exists: config/config.py

Step 11: Creating reports directory...
✅ Reports directory created: reports/load_tests

Step 12: Final verification...
✅ Core dependencies imported successfully
✅ Python imports working correctly

================================================================================
✅ Setup Complete!

## 🔧 Manual Setup (Alternative)

If you prefer manual setup or the script doesn't work:

```bash
# 1. Create virtual environment
python3 -m venv venv

# 2. Activate it
source venv/bin/activate

# 3. Upgrade pip
pip install --upgrade pip

# 4. Install dependencies
pip install -r requirements.txt

# 5. Validate
python3 tests/load_tests/validate_function_signature.py
```

## ✅ Verification Checklist

After setup, verify everything works:

- [ ] Virtual environment created and activated
- [ ] All dependencies installed (`pip list` shows selenium, pytest, etc.)
- [ ] Function signature validated (no errors)
- [ ] Chrome browser accessible
- [ ] Project structure intact
- [ ] Reports directory created

## 🐛 Troubleshooting

### Issue: "Permission denied" when running setup script

**Solution:**
```bash
chmod +x setup_load_test_environment.sh
./setup_load_test_environment.sh
```

### Issue: "Python 3 not found"

**Solution:**
```bash
# Ubuntu/Debian
sudo apt-get update
sudo apt-get install python3 python3-pip python3-venv

# Or check if python3 is installed
which python3
```

### Issue: "pip install fails"

**Solution:**
```bash
# Upgrade pip first
python3 -m pip install --upgrade pip

# Then install requirements
pip install -r requirements.txt
```

### Issue: "Chrome not found"

**Solution:**
```bash
# Ubuntu/Debian
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo dpkg -i google-chrome-stable_current_amd64.deb
sudo apt-get install -f  # Fix dependencies if needed
```

**Note:** webdriver-manager will handle ChromeDriver automatically, so you don't need to install it manually.
