## 🎯 What is This?
This is a **world-class load testing script** that simulates multiple students completing the full assessment flow simultaneously. It's designed to:
- ✅ Test backend/server performance under load
- ✅ Verify system stability with concurrent users
- ✅ Provide transparent, real-time metrics
- ✅ Support multi-device execution (distributed load testing)
- ✅ Use only 100% verified, reliable automation flows
### What Each Student Does
**Complete Flow (9 Steps):**
1. **Login** → Excel password first, fallback to Admin@123
2. **Password Reset** → If modal appears (smart detection)
3. **Profile Fill** → Complete to 100% if incomplete (smart detection)
4. **Navigate to Assessments** → Go to assessments page
5. **Start Assessment** → Click first available assessment
6. **Select Domain** → Click first unlocked domain
7. **Answer All Questions** → Answer all questions in domain (handles all 5 question types)
8. **Submit Assessment** → Submit when all questions answered
9. **Feedback** → Submit domain feedback if modal appears
**Total Time:** ~3-5 minutes per student (depending on number of questions)
---
## 📋 Prerequisites
### Required
- ✅ Python 3.8+
- ✅ Virtual environment activated
- ✅ Chrome browser installed
- ✅ ChromeDriver installed
- ✅ CSV file with student data
- ✅ Backend server running (localhost:3983 for local)
### CSV File Format
Your CSV file must have these columns (case-insensitive):
- `Student CPID` or `student_cpid` or `cpid` or `CPID` (required)
- `Password` or `password` or `PASSWORD` (optional, will use Admin@123 if missing)
- `First Name` (optional, for display)
- `Last Name` (optional, for display)
**Example CSV:**
```csv
Student CPID,Password,First Name,Last Name
STU001,Pass123,John,Doe
STU002,Pass456,Jane,Smith
```
---
## 🚀 Quick Start
### Step 1: Activate Virtual Environment
```bash
cd /home/tech4biz/work/CP_Front_Automation_Test
source venv/bin/activate
```
### Step 2: Validate Function Signature (Recommended)
```bash
python3 tests/load_tests/validate_function_signature.py
```
**Expected Output:** ✅ Function signature is valid!
### Step 3: Run Your First Test (1 Student)
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 0 \
--end 1 \
--workers 1 \
--headless \
--metrics-interval 1
```
### Step 4: Scale Up (10 Students)
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 0 \
--end 10 \
--workers 10 \
--headless \
--metrics-interval 5
```
### Step 5: Full Load Test (100 Students)
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 0 \
--end 100 \
--workers 100 \
--headless \
--metrics-interval 10
```

## 🔍 Understanding the Flow
### What Happens Behind the Scenes
1. **Script starts** → Loads students from CSV (with range filter)
2. **For each student** (in parallel):
- Creates Chrome browser (headless or visible)
- Logs in (smart password handling)
- Handles password reset if needed
- Completes profile if needed
- Navigates to assessments
- Starts first assessment
- Selects first domain
- Answers ALL questions
- Submits assessment
- Handles feedback
- Closes browser
3. **Metrics collected** → Real-time performance tracking
4. **Results saved** → JSON report generated
### Smart Features
- **Smart Login**: Tries Excel password first, falls back to Admin@123
- **Smart Password Reset**: Only resets if needed (checks current password state)
- **Smart Profile Completion**: Only completes if profile is incomplete
- **Smart Question Answering**: Handles all 5 question types automatically
- **Smart Error Recovery**: Retries on transient failures

## 🌐 Multi-Device Execution
This script supports **distributed load testing** across multiple devices. Each device runs a different range of students.
### Example: 500 Students on 5 Devices
**Device 1** (Students 0-99):
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 0 \
--end 100 \
--workers 100 \
--headless
```
**Device 2** (Students 100-199):
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 100 \
--end 200 \
--workers 100 \
--headless
```
**Device 3** (Students 200-299):
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 200 \
--end 300 \
--workers 100 \
--headless
```
**Device 4** (Students 300-399):
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 300 \
--end 400 \
--workers 100 \
--headless
```
**Device 5** (Students 400-500):
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 400 \
--end 500 \
--workers 100 \
--headless
```
### Range Calculation
- `--start 0 --end 100` = Students at indices 0-99 (100 students)
- `--start 100 --end 200` = Students at indices 100-199 (100 students)
- `--start 0 --end 500` = Students at indices 0-499 (500 students)
**Note:** Index 0 is the first student (after header row in CSV)

## 🔧 Troubleshooting
### Issue: "No module named 'utils'"
**Solution:**
```bash
# Make sure you're in the project root
cd /home/tech4biz/work/CP_Front_Automation_Test
source venv/bin/activate
```
### Issue: "TypeError: got multiple values for argument 'headless'"
**Status:** ✅ **FIXED** - This was resolved by adding `user_id` as first parameter
**Verification:**
```bash
python3 tests/load_tests/validate_function_signature.py
```
### Issue: "No students loaded"
**Causes:**
- CSV path is incorrect
- `--start` and `--end` are invalid
- CSV doesn't have `Student CPID` column
**Solution:**
- Check CSV path is correct
- Verify `--start` < `--end`
- Ensure CSV has required columns
### Issue: High Failure Rate
**Possible Causes:**
- Too many concurrent browsers (reduce `--workers`)
- System resources exhausted (RAM/CPU)
- Backend server overloaded
- Network issues
**Solutions:**
- Reduce `--workers` to 20-50
- Monitor system resources (`htop`, `free -h`)
- Check backend server logs
- Test with smaller batch first
### Issue: "DevToolsActivePort file doesn't exist"
**Cause:** Too many Chrome instances trying to start simultaneously
**Solution:**
- Reduce `--workers` (try 20-50)
- Add delay between browser starts
- Use headless mode (`--headless`)
### Issue: Slow Execution
**Causes:**
- Too many concurrent browsers
- System resources limited
- Network latency
- Backend server slow
**Solutions:**
- Use `--headless` mode (faster)
- Reduce `--workers`
- Check network connection
- Monitor backend performance
---
## 💡 Best Practices
### 1. Start Small, Scale Up
- ✅ Test with 1 student first
- ✅ Then 10 students
- ✅ Then 50 students
- ✅ Finally 100+ students
### 2. Use Headless Mode
- ✅ Always use `--headless` for load testing
- ✅ Much faster and more stable
- ✅ Lower resource usage
- ✅ Use `--visible` only for debugging
### 3. Monitor System Resources
```bash
# In another terminal, monitor:
watch -n 1 'ps aux | grep chrome | wc -l' # Count Chrome processes
htop # Monitor CPU/RAM
free -h # Check memory
```
### 4. Validate Before Running
```bash
# Always validate signature first
python3 tests/load_tests/validate_function_signature.py
```
### 5. Use Appropriate Concurrency
- **Small test (1-10 students)**: `--workers` = number of students
- **Medium test (10-50 students)**: `--workers` = 20-50
- **Large test (50-100 students)**: `--workers` = 50-100
- **Very large test (100+ students)**: `--workers` = 100 (or use multi-device)
### 6. Multi-Device Strategy
- Divide students evenly across devices
- Each device runs 100-200 students
- All devices run simultaneously
- Combine results from all devices
### 7. Metrics Interval
- **Short tests (< 50 students)**: `--metrics-interval 5`
- **Medium tests (50-100 students)**: `--metrics-interval 10`
- **Long tests (100+ students)**: `--metrics-interval 20`
---
## 🚀 Advanced Usage
### Custom Range Testing
**Test specific students:**
```bash
# Students 50-75
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students.csv \
--start 50 \
--end 75 \
--workers 25
```
### Resuming Failed Tests
If a test fails, you can resume by running the same command with adjusted `--start`:
```bash
# Original: --start 0 --end 100 (failed at student 50)
# Resume from student 50:
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students.csv \
--start 50 \
--end 100 \
--workers 50
```
### Performance Analysis
**Analyze JSON report:**
```python
import json
with open('reports/load_tests/load_test_Complete_Assessment_Flow_100users_*.json') as f:
data = json.load(f)
summary = data['summary']
print(f"Success Rate: {summary['success_rate']:.2f}%")
print(f"Avg Duration: {summary['avg_duration']:.2f}s")
print(f"P95 Duration: {summary['p95_duration']:.2f}s")
```

## 📝 Notes
### Password Strategy
- **Excel password** is tried first (from CSV)
- **Admin@123** is used as fallback
- Password reset only happens if needed (smart detection)
### Assessment Flow
- Completes **ONE domain** (first unlocked domain)
- Answers **ALL questions** in that domain
- Handles **all 5 question types** automatically
- Submits when all questions answered
### Error Handling
- Robust retry logic for transient failures
- Smart error recovery
- Comprehensive error logging
- Driver cleanup on errors
### Resource Management
- Automatic browser cleanup
- Thread pool management
- Memory-efficient execution
- Progress tracking
---
## ✅ Verification Checklist
Before running a large load test:
- [ ] Virtual environment activated
- [ ] Function signature validated (`validate_function_signature.py`)
- [ ] CSV file exists and has correct format
- [ ] Backend server is running
- [ ] Tested with 1 student first
- [ ] System resources are adequate
- [ ] Using headless mode for load testing
- [ ] Appropriate `--workers` value set
- [ ] Monitoring system resources
---
## 🆘 Getting Help
### Check These First:
1. Run validation script: `python3 tests/load_tests/validate_function_signature.py`
2. Test with 1 student first
3. Check system resources
4. Review error messages in JSON report
5. Check backend server logs
### Common Questions:
**Q: How many students can I run simultaneously?**
A: Depends on system resources. Start with 20-50, scale up based on performance.
**Q: Can I run this on multiple machines?**
A: Yes! Use `--start` and `--end` to divide students across machines.
**Q: How long does it take?**
A: ~3-5 minutes per student. 100 students = ~5-8 hours (depending on concurrency).
**Q: What if a student fails?**
A: The script continues with other students. Check the JSON report for details.
**Q: Can I pause and resume?**
A: Not automatically, but you can use `--start` to resume from a specific index.

# Load Test Script - Issue Analysis & Resolution
## 🔴 The Original Issue
**Error from JSON report:**
```
TypeError: complete_assessment_flow_for_student() got multiple values for argument 'headless'
```
**Root Cause:**
1. `LoadTestBase.execute_test_for_user()` calls: `test_function(user_id, *args, **kwargs)`
2. We were calling it with: `execute_test_for_user(user_id=1, func, student_info, idx, headless=True)`
3. This becomes: `func(1, student_info, idx, headless=True)`
4. **Original function signature** (BROKEN):
```python
def complete_assessment_flow_for_student(
student_info: Dict, # ← Expected student_info first, but got user_id=1!
student_index: int,
headless: bool = True
)
```
5. Python tried to assign:
- `student_info = 1` ❌ (wrong type!)
- `student_index = student_info` ❌ (wrong!)
- `headless = idx` ❌ (wrong!)
- Then `headless=True` in kwargs → **CONFLICT!** ❌
## ✅ The Fix
**New function signature** (CORRECT):
```python
def complete_assessment_flow_for_student(
user_id: int, # ← Now accepts user_id as first parameter
student_info: Dict,
student_index: int,
headless: bool = True
)
```
**Now when called:**
- `func(1, student_info, idx, headless=True)`
- Python correctly assigns:
- `user_id = 1` ✅
- `student_info = student_info` ✅
- `student_index = idx` ✅
- `headless = True` ✅
## ✅ Verification Steps Completed
1. ✅ **Function signature fixed** - Added `user_id` as first parameter
2. ✅ **Validation script created** - `validate_function_signature.py` confirms signature is correct
3. ✅ **Input validation added** - Validates all inputs before execution
4. ✅ **Error handling enhanced** - Better error messages and cleanup
5. ✅ **Pre-submission validation** - Validates students before submitting to thread pool
## 🧪 How to Verify It Works
### Step 1: Validate Signature
```bash
cd /home/tech4biz/work/CP_Front_Automation_Test
source venv/bin/activate
python3 tests/load_tests/validate_function_signature.py
```
**Expected:** ✅ Function signature is valid!
### Step 2: Test with 1 Student (Dry Run)
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 0 \
--end 1 \
--workers 1 \
--headless \
--metrics-interval 1
```
**Expected:** Should complete successfully without the TypeError
### Step 3: Test with 10 Students
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 0 \
--end 10 \
--workers 10 \
--headless \
--metrics-interval 5
```
### Step 4: Full Load Test (100+ Students)
```bash
python3 tests/load_tests/test_generic_load_assessments.py \
--csv students_with_passwords_2025-12-12T13-19-32.csv \
--start 0 \
--end 100 \
--workers 100 \
--headless \
--metrics-interval 10
```
## 📋 What Each Student Does
**Complete Flow:**
1. **Login** - Excel password first, fallback to Admin@123
2. **Password Reset** - If modal appears (smart detection)
3. **Profile Fill** - Complete to 100% if incomplete (smart detection)
4. **Navigate to Assessments** - Go to assessments page
5. **Start Assessment** - Click first available assessment
6. **Select Domain** - Click first unlocked domain
7. **Answer All Questions** - Answer all questions in domain (handles all 5 question types)
8. **Submit Assessment** - Submit when all questions answered
9. **Feedback** - Submit domain feedback if modal appears
## 🎯 Current Status
- ✅ **Issue Identified**: Function signature mismatch
- ✅ **Issue Fixed**: Added `user_id` as first parameter
- ✅ **Validated**: Signature validation script confirms fix
- ⚠️ **Not Yet Tested**: Need to run actual test to confirm it works end-to-end
## 🚀 Next Steps
1. Run validation script (already done - ✅ passed)
2. Run test with 1 student to verify end-to-end
3. If successful, scale up to 10, then 100, then 500
## 🔍 Code Flow Verification
**Call Chain:**
```
run_load_test()
└─> executor.submit(execute_test_for_user, user_id, func, student_info, idx, headless=True)
└─> execute_test_for_user()
└─> test_function(user_id, *args, **kwargs)
└─> complete_assessment_flow_for_student(user_id, student_info, idx, headless=True) ✅
```
**This matches perfectly now!**

<#
.Synopsis
Activate a Python virtual environment for the current PowerShell session.
.Description
Pushes the python executable for a virtual environment to the front of the
$Env:PATH environment variable and sets the prompt to signify that you are
in a Python virtual environment. Makes use of the command line switches as
well as the `pyvenv.cfg` file values present in the virtual environment.
.Parameter VenvDir
Path to the directory that contains the virtual environment to activate. The
default value for this is the parent of the directory that the Activate.ps1
script is located within.
.Parameter Prompt
The prompt prefix to display when this virtual environment is activated. By
default, this prompt is the name of the virtual environment folder (VenvDir)
surrounded by parentheses and followed by a single space (ie. '(.venv) ').
.Example
Activate.ps1
Activates the Python virtual environment that contains the Activate.ps1 script.
.Example
Activate.ps1 -Verbose
Activates the Python virtual environment that contains the Activate.ps1 script,
and shows extra information about the activation as it executes.
.Example
Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
Activates the Python virtual environment located in the specified location.
.Example
Activate.ps1 -Prompt "MyPython"
Activates the Python virtual environment that contains the Activate.ps1 script,
and prefixes the current prompt with the specified string (surrounded in
parentheses) while the virtual environment is active.
.Notes
On Windows, it may be required to enable this Activate.ps1 script by setting the
execution policy for the user. You can do this by issuing the following PowerShell
command:
PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
For more information on Execution Policies:

.Synopsis
Remove all shell session elements added by the Activate script, including the
addition of the virtual environment's Python executable from the beginning of
the PATH variable.
.Parameter NonDestructive
If present, do not remove this function from the global namespace for the
session.

.Description
Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
given folder, and returns them in a map.
For each line in the pyvenv.cfg file, if that line can be parsed into exactly
two strings separated by `=` (with any amount of whitespace surrounding the =)
then it is considered a `key = value` line. The left hand string is the key,
the right hand is the value.
If the value starts with a `'` or a `"` then the first and last character is
stripped from the value before being captured.
.Parameter ConfigDir
Path to the directory that contains the `pyvenv.cfg` file.
