+Apply performance monitoring concepts from performance-test-guide.md to the specified test file: $ARGUMENTS
+
+## Task Overview
+Transform browser tests to include performance monitoring for canvas, node, and widget operations following the established performance testing patterns.
+
+## Instructions
+
+
+1. **Read the target test file** specified in $ARGUMENTS
+2. **Analyze test operations** to identify which ones should have performance monitoring based on the guide criteria:
+ - โ
**Monitor**: Node operations, widget interactions, canvas operations, graph operations, background operations
+ - โ **Skip**: UI chrome elements, dialogs/modals, floating menus, gallery/template views
+3. **Review existing test structure** to understand the test flow and key operations
+
+
+
+4. **Add performance monitoring** following these steps:
+
+ **a. Import and setup:**
+ - Add `import { PerformanceMonitor } from '../helpers/performanceMonitor'`
+ - Add `@perf` tag to test name
+ - Initialize PerformanceMonitor with `comfyPage.page`
+ - Create descriptive kebab-case test name
+ - Call `startMonitoring(testName)`
+
+ **b. Wrap appropriate operations:**
+ - Use `measureOperation()` for node operations (creating, selecting, dragging, copying, deleting)
+ - Use `measureOperation()` for widget interactions (input changes, clicks, value modifications)
+ - Use `measureOperation()` for canvas operations (panning, zooming, selections, connections)
+ - Use `measureOperation()` for graph operations (loading workflows, undo/redo, batch operations)
+ - Use `markEvent()` for logical boundaries and state transitions
+ - Group related operations when they represent a single user action
+ - Keep assertions and expectations outside performance measurements
+
+ **c. Apply appropriate patterns:**
+ - **User Interaction Sequence**: Separate click, type, submit operations
+ - **Copy/Paste Operations**: Separate select, copy, paste with before/after marks
+ - **Drag Operations**: Separate start-drag, drag-to-position, drop
+
+ **d. Finalize:**
+ - Call `finishMonitoring(testName)` at the end
+ - Ensure all async operations are properly wrapped
+
+
+
+- **Test names**: kebab-case, descriptive (e.g., 'copy-paste-multiple-nodes')
+- **Operation names**: kebab-case, action-focused (e.g., 'click-node', 'drag-to-position')
+- **Event marks**: kebab-case, state-focused (e.g., 'before-paste', 'after-render')
+
+
+
+- **Balance granularity**: Don't wrap every line, focus on meaningful operations
+- **Maintain readability**: Wrapped code should remain clear and understandable
+- **Preserve test logic**: Don't change test functionality, only add monitoring
+- **Keep consistency**: Use similar operation names across similar tests
+- **Group intelligently**: Combine related operations that represent single user actions
+
+
+## Expected Output
+
+Transform the test file to include:
+1. Performance monitor import and initialization
+2. `@perf` tag in test name
+3. Appropriate `measureOperation()` wrapping for qualifying operations
+4. `markEvent()` calls for logical boundaries
+5. `finishMonitoring()` call at the end
+6. Preserved test assertions and expectations outside performance measurements
+
+Show the complete transformed test file with clear before/after comparison if the changes are substantial.
+
+## Example Transformation Reference
+
+Follow this pattern for transformation:
+
+**Before:**
+```typescript
+test('Can copy and paste node', async ({ comfyPage }) => {
+ await comfyPage.clickEmptyLatentNode()
+ await comfyPage.ctrlC()
+ await comfyPage.ctrlV()
+ await expect(comfyPage.canvas).toHaveScreenshot('copied-node.png')
+})
+```
+
+**After:**
+```typescript
+test('@perf Can copy and paste node', async ({ comfyPage }) => {
+ const perfMonitor = new PerformanceMonitor(comfyPage.page)
+ const testName = 'copy-paste-node'
+
+ await perfMonitor.startMonitoring(testName)
+
+ await perfMonitor.measureOperation('click-node', async () => {
+ await comfyPage.clickEmptyLatentNode()
+ })
+
+ await perfMonitor.measureOperation('copy-node', async () => {
+ await comfyPage.ctrlC()
+ })
+
+ await perfMonitor.measureOperation('paste-node', async () => {
+ await comfyPage.ctrlV()
+ })
+
+ await expect(comfyPage.canvas).toHaveScreenshot('copied-node.png')
+
+ await perfMonitor.finishMonitoring(testName)
+})
+```
+
+Now apply these concepts to the test file: $ARGUMENTS

+# Performance Test Wrapping Guide
+
+This guide explains how to add performance monitoring to browser tests for canvas, node, and widget operations.
+
+## When to Add Performance Monitoring
+
+### โ
Add `@perf` tag and wrappers for:
+- **Node operations**: Creating, selecting, dragging, copying, deleting nodes
+- **Widget interactions**: Input changes, widget clicks, value modifications
+- **Canvas operations**: Panning, zooming, selections, connections between nodes
+- **Graph operations**: Loading workflows, undo/redo, batch operations
+- **Background/general operations**: Workflow execution, queue management, model loading
+
+### โ Skip performance monitoring for:
+- **UI chrome elements**: Menubar, topbar, sidebars, action bars
+- **Dialogs and modals**: Settings, prompts, confirmations
+- **Floating menus**: Context menus, tooltips
+- **Gallery/template views**: Template selection, preview panels
+
+## Available Performance Monitor Methods
+
+1. **`startMonitoring(testName: string)`** - Initialize performance tracking
+2. **`measureOperation(operationName: string, operation: () => Promise)`** - Wrap async operations to measure duration
+3. **`markEvent(eventName: string)`** - Mark specific points in time
+4. **`finishMonitoring(testName: string)`** - Collect all metrics and cleanup
+
+## Step-by-Step Implementation
+
+### 1. Import the Performance Monitor
+```typescript
+import { PerformanceMonitor } from '../helpers/performanceMonitor'
+```
+
+### 2. Add @perf Tag to Test Name
+```typescript
+test('@perf Your test description', async ({ comfyPage }) => {
+ // test implementation
+})
+```
+
+### 3. Initialize Performance Monitor
+```typescript
+const perfMonitor = new PerformanceMonitor(comfyPage.page)
+const testName = 'descriptive-test-name' // Use kebab-case
+
+await perfMonitor.startMonitoring(testName)
+```
+
+### 4. Wrap Operations Based on Context
+
+#### For Simple Actions
+```typescript
+await perfMonitor.measureOperation('operation-name', async () => {
+ await comfyPage.someAction()
+})
+```
+
+#### For Multi-Step Operations
+```typescript
+// Mark the beginning of a sequence
+await perfMonitor.markEvent('sequence-start')
+
+// Measure individual steps
+await perfMonitor.measureOperation('step-1', async () => {
+ await firstAction()
+})
+
+await perfMonitor.measureOperation('step-2', async () => {
+ await secondAction()
+})
+
+// Mark the end
+await perfMonitor.markEvent('sequence-end')
+```
+
+#### For Operations with Return Values
+```typescript
+let result: SomeType
+await perfMonitor.measureOperation('get-value', async () => {
+ result = await getValue()
+})
+// Use result! with non-null assertion
+```
+
+### 5. Finish Monitoring
+```typescript
+await perfMonitor.finishMonitoring(testName)
+```
+
+## Naming Conventions
+
+- **Test names**: Use kebab-case, be descriptive (e.g., `'copy-paste-multiple-nodes'`)
+- **Operation names**: Use kebab-case, describe the action (e.g., `'click-node'`, `'drag-to-position'`)
+- **Event marks**: Use kebab-case for states or points in time (e.g., `'before-paste'`, `'after-render'`)
+
+## Common Patterns
+
+### Pattern 1: User Interaction Sequence
+```typescript
+await perfMonitor.measureOperation('click-element', async () => {
+ await element.click()
+})
+
+await perfMonitor.measureOperation('type-text', async () => {
+ await element.type('text')
+})
+
+await perfMonitor.measureOperation('submit-form', async () => {
+ await element.press('Enter')
+})
+```
+
+### Pattern 2: Copy/Paste Operations
+```typescript
+await perfMonitor.measureOperation('select-item', async () => {
+ await selectItem()
+})
+
+await perfMonitor.measureOperation('copy-operation', async () => {
+ await comfyPage.ctrlC()
+})
+
+await perfMonitor.markEvent('before-paste')
+
+await perfMonitor.measureOperation('paste-operation', async () => {
+ await comfyPage.ctrlV()
+})
+
+await perfMonitor.markEvent('after-paste')
+```
+
+### Pattern 3: Drag Operations
+```typescript
+await perfMonitor.measureOperation('start-drag', async () => {
+ await page.mouse.down()
+})
+
+await perfMonitor.measureOperation('drag-to-position', async () => {
+ await page.mouse.move(x, y)
+})
+
+await perfMonitor.measureOperation('drop', async () => {
+ await page.mouse.up()
+})
+```
+
+## Adapting to Individual Test Cases
+
+### Consider the test's focus:
+1. **Granularity**: For complex operations, break down into smaller measurements
+2. **Key actions**: Focus on the primary actions being tested
+3. **Skip trivial operations**: Don't wrap every single line (e.g., simple variable assignments)
+4. **Meaningful boundaries**: Use `markEvent` for logical boundaries in the test flow
+
+### Example of discretion:
+```typescript
+// Too granular - avoid this
+await perfMonitor.measureOperation('get-textbox', async () => {
+ const textBox = comfyPage.widgetTextBox
+})
+
+// Better - group related operations
+const textBox = comfyPage.widgetTextBox
+await perfMonitor.measureOperation('interact-with-textbox', async () => {
+ await textBox.click()
+ await textBox.selectText()
+})
+```
+
+## What Gets Measured
+
+The performance monitor automatically captures:
+- **Memory usage**: JS heap size and limits
+- **Timing metrics**: Page load, DOM ready, paint events
+- **Custom operations**: Duration of wrapped operations
+- **Marked events**: Timestamps of specific points
+
+## Performance Data Persistence
+
+### Automatic Collection
+All performance metrics from `@perf` tests are automatically collected and saved to JSON files at the end of the test run via global teardown.
+
+### File Output Structure
+```
+test-results/performance/
+โโโ run-2024-01-15T10-30-45-123Z.json # Timestamped run file
+โโโ latest.json # Always points to most recent run
+```
+
+### JSON Schema
+Each run file contains:
+```typescript
+{
+ "runId": "run-2024-01-15T10-30-45-123Z",
+ "timestamp": 1705315845123,
+ "branch": "vue-widget/perf-test",
+ "gitCommit": "abc123def456",
+ "environment": {
+ "nodeVersion": "v18.17.0",
+ "playwrightVersion": "1.40.0",
+ "os": "linux"
+ },
+ "testMetrics": [
+ {
+ "testName": "copy-paste-node",
+ "timestamp": 1705315845000,
+ "branch": "vue-widget/perf-test",
+ "memoryUsage": {
+ "usedJSHeapSize": 91700000,
+ "totalJSHeapSize": 109000000,
+ "jsHeapSizeLimit": 3760000000
+ },
+ "timing": {
+ "firstPaint": 162.3,
+ "firstContentfulPaint": 162.3,
+ "domContentLoaded": 276.7
+ },
+ "customMetrics": {
+ "click-node": 80.3,
+ "copy-operation": 37.1,
+ "paste-operation": 36.0
+ }
+ }
+ ]
+}
+```
+
+### Comparing Across Runs
+- Each run generates a unique timestamped file for historical tracking
+- Use `latest.json` for current run comparisons
+- Git branch and commit info included for correlation with code changes
+- Environment metadata helps identify platform-specific performance differences
+
+## Tips
+
+1. **Keep operation names consistent** across similar tests
+2. **Don't wrap expectations** - Keep assertions outside performance measurements
+3. **Group related operations** when they represent a single user action
+4. **Use markEvent** for state transitions or important moments
+5. **Balance detail with readability** - The wrapped code should still be easy to understand
+
+## Example: Complete Test Transformation
+
+### Before:
+```typescript
+test('Can copy and paste node', async ({ comfyPage }) => {
+ await comfyPage.clickEmptyLatentNode()
+ await comfyPage.page.mouse.move(10, 10)
+ await comfyPage.ctrlC()
+ await comfyPage.ctrlV()
+ await expect(comfyPage.canvas).toHaveScreenshot('copied-node.png')
+})
+```
+
+### After:
+```typescript
+test('@perf Can copy and paste node', async ({ comfyPage }) => {
+ const perfMonitor = new PerformanceMonitor(comfyPage.page)
+ const testName = 'copy-paste-node'
+
+ await perfMonitor.startMonitoring(testName)
+
+ await perfMonitor.measureOperation('click-node', async () => {
+ await comfyPage.clickEmptyLatentNode()
+ })
+
+ await perfMonitor.measureOperation('position-mouse', async () => {
+ await comfyPage.page.mouse.move(10, 10)
+ })
+
+ await perfMonitor.measureOperation('copy-node', async () => {
+ await comfyPage.ctrlC()
+ })
+
+ await perfMonitor.measureOperation('paste-node', async () => {
+ await comfyPage.ctrlV()
+ })
+
+ // Screenshot assertion stays outside performance monitoring
+ await expect(comfyPage.canvas).toHaveScreenshot('copied-node.png')
+
+ await perfMonitor.finishMonitoring(testName)
+})
+```
