# 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!**
