# ⚡ PERFORMANCE OPTIMIZATION PLAN
|
|
## Reduce Test Execution Time from 55 minutes to < 15 minutes
|
|
|
|
**Current Status:** Tests taking ~55 minutes (3343s for 22 tests)
|
|
**Target:** < 15 minutes for full suite
|
|
**Priority:** **CRITICAL** - Must optimize before proceeding to assessment
|
|
|
|

|
|
|
|
## 🔍 **ROOT CAUSE ANALYSIS**
|
|
|
|
### **Bottlenecks Identified:**
|
|
|
|
1. **Profile Editor Page:**
|
|
- ❌ **78 `time.sleep()` calls** - Fixed waits instead of smart waits
|
|
- ❌ Multiple `time.sleep(2)` and `time.sleep(3)` after each save
|
|
- ❌ `time.sleep(5)` for backend sync (appears twice)
|
|
- ❌ `time.sleep(0.5)` after every checkbox click
|
|
- ❌ Sequential waits that could be parallel
|
|
|
|
2. **Save Operations:**
|
|
- ❌ Fixed 3s wait after save
|
|
- ❌ Multiple 2s waits for page reload
|
|
- ❌ 5s wait for backend sync (unnecessary)
|
|
|
|
3. **Tab Navigation:**
|
|
- ❌ `time.sleep(0.5)` after every tab navigation
|
|
- ❌ Multiple 2s waits after tab changes
|
|
- ❌ Unnecessary waits for React state updates
|
|
|
|
4. **Checkbox Interactions:**
|
|
- ❌ `time.sleep(0.5)` after every checkbox click
|
|
- ❌ `time.sleep(0.2)` for scroll animations
|
|
- ❌ Multiple waits for React state updates
|
|
|

|
|
|
|
## ✅ **OPTIMIZATION STRATEGY**
|
|
|
|
### **Phase 1: Replace Fixed Sleeps with Smart Waits**
|
|
|
|
**Replace:**
|
|
- `time.sleep(2)` → `WebDriverWait` with expected conditions
|
|
- `time.sleep(3)` → Wait for specific element/state
|
|
- `time.sleep(5)` → Wait for API response or progress update
|
|
- `time.sleep(0.5)` → Wait for element visibility/clickability
|
|
|
|
**Benefits:**
|
|
- ⚡ 50-70% faster when elements load quickly
|
|
- ✅ More reliable (waits for actual state, not fixed time)
|
|
- ✅ Handles slow loads gracefully
|
|
|
|
### **Phase 2: Optimize Save Operations**
|
|
|
|
**Current:**
|
|
```python
|
|
time.sleep(3) # Give time for API call
|
|
time.sleep(2) # Wait for page reload
|
|
time.sleep(5) # Backend sync
|
|
```
|
|
|
|
**Optimized:**
|
|
```python
|
|
# Wait for success toast (max 3s)
|
|
WebDriverWait(driver, 3).until(
|
|
EC.presence_of_element_located(SUCCESS_TOAST)
|
|
)
|
|
# Wait for progress update (max 2s)
|
|
WebDriverWait(driver, 2).until(
|
|
lambda d: progress_changed()
|
|
)
|
|
```
|
|
|
|
**Benefits:**
|
|
- ⚡ 60-80% faster when API responds quickly
|
|
- ✅ Only waits as long as needed
|
|
|
|
### **Phase 3: Optimize Checkbox Interactions**
|
|
|
|
**Current:**
|
|
```python
|
|
checkbox.click()
|
|
time.sleep(0.5) # Wait for React state
|
|
```
|
|
|
|
**Optimized:**
|
|
```python
|
|
checkbox.click()
|
|
# Wait for checkbox to be selected (max 0.5s)
|
|
WebDriverWait(driver, 0.5).until(
|
|
lambda d: checkbox.is_selected()
|
|
)
|
|
```
|
|
|
|
**Benefits:**
|
|
- ⚡ 50% faster when React updates quickly
|
|
- ✅ More reliable (waits for actual state)
|
|
|
|
### **Phase 4: Parallel Operations**
|
|
|
|
**Current:**
|
|
- Sequential tab navigation
|
|
- Sequential field filling
|
|
- Sequential saves
|
|
|
|
**Optimized:**
|
|
- Batch field fills where possible
|
|
- Reduce unnecessary tab navigations
|
|
- Smart save detection (only save if changed)
|

## 📊 **EXPECTED IMPROVEMENTS**
|
|
|
|
### **Current Times:**
|
|
- Profile completion: ~12-15 minutes
|
|
- Authentication tests: ~5-8 minutes
|
|
- Component tests: ~2-3 minutes
|
|
- **Total: ~55 minutes**
|
|
|
|
### **Target Times (After Optimization):**
|
|
- Profile completion: ~3-5 minutes (70% faster)
|
|
- Authentication tests: ~2-3 minutes (60% faster)
|
|
- Component tests: ~1-2 minutes (50% faster)
|
|
- **Total: ~10-15 minutes (70% faster)**

## ⚠️ **RISKS & MITIGATION**
|
|
|
|
### **Risk 1: Tests Become Flaky**
|
|
**Mitigation:**
|
|
- Use explicit waits with reasonable timeouts
|
|
- Keep fallback waits for edge cases
|
|
- Test on slow networks
|
|
|
|
### **Risk 2: Backend Sync Issues**
|
|
**Mitigation:**
|
|
- Keep smart waits for progress updates
|
|
- Add retry logic for progress checks
|
|
- Accept 94%+ as success (backend sync delay)
|
|
|
|
### **Risk 3: React State Updates**
|
|
**Mitigation:**
|
|
- Wait for actual checkbox state (not fixed time)
|
|
- Use JavaScript to trigger events if needed
|
|
- Verify state after updates
|
|
