+# PatternFly Cypress Commands - Usage Examples
+
+This file provides comprehensive examples of PatternFly-aware Cypress commands for distributed tracing UI testing, focusing on semantic selectors and efficient testing patterns.
+
+## ✅ Recommended Usage Patterns
+
+### 1. Simple Component Interactions
+
+```typescript
+// Empty State - Clean and reliable
+cy.pfEmptyState().within(() => {
+  cy.byRole('heading').should('contain', 'No items found');
+});
+
+// Buttons - Direct and stable
+cy.pfButton('Create Instance').click();
+cy.pfButton('Save Changes').should('be.disabled');
+cy.pfButton('Cancel').should('be.visible');
+```
+
+### 2. Menu Navigation
+
+```typescript
+// Basic menu toggle
+cy.pfMenuToggle('Select Instance').click();
+cy.pfMenuItem('TempoStack').click();
+
+// Or with error handling for dynamic content
+cy.get('body').then(($body) => {
+  if ($body.find('.pf-v6-c-menu-toggle:contains("Create Instance")').length > 0) {
+    cy.pfMenuToggle('Create Instance').click();
+    cy.pfMenuItem('TempoStack Instance').click();
+  }
+});
+```
+
+### 3. Toolbar Interactions (Recommended Approach)
+
+```typescript
+// Simple toolbar item selection
+cy.pfToolbarItem(0).within(() => {
+  cy.get('.pf-v6-c-menu-toggle, .pf-v5-c-menu-toggle').first().click();
+});
+cy.get('.pf-v6-c-menu__item, .pf-v5-c-menu__item').contains('Option 1').click();
+
+// Wait for stability between interactions
+cy.wait(1000);
+cy.pfToolbarItem(1).within(() => {
+  cy.get('.pf-v6-c-menu-toggle, .pf-v5-c-menu-toggle').first().click();
+});
+```
+
+### 4. Form Interactions
+
+```typescript
+// Using label-based selection
+cy.byLabelText('Instance Name').type('my-instance');
+cy.byLabelText('Namespace').select('default');
+
+// Form submission
+cy.pfButton('Submit').click();
+```
+
+## 🆕 New Distributed Tracing UI Commands
+
+### Menu & Dropdown Interactions
+
+```typescript
+// Tempo instance selection
+cy.pfTypeahead('Select a Tempo instance').click();
+cy.pfSelectMenuItem('chainsaw-rbac / simplst').click();
+
+// Service filtering with checkboxes
+cy.pfMenuToggleByLabel('Multi typeahead checkbox').click();
+cy.pfCheckMenuItem('http-rbac-1');
+cy.pfCheckMenuItem('http-rbac-2', true);    // Explicitly check
+cy.pfCheckMenuItem('grpc-rbac-1', false);   // Uncheck
+
+// Time range selection
+cy.pfMenuToggle('Last 30 minutes').click();
+cy.pfSelectMenuItem('Last 1 hour').click();
+```
+
+### Navigation Commands
+
+```typescript
+// Breadcrumb navigation
+cy.pfBreadcrumb('Traces').click();
+cy.pfBreadcrumb('Observability').should('be.visible');
+
+// Close buttons (chip groups, modals, etc.)
+cy.pfCloseButton('Close chip group').click();      // PatternFly 5
+cy.pfCloseButton('Close label group').click();     // PatternFly 6
+cy.pfCloseButton().click();                        // First close button found (any version)
+```
+
+### Trace & Span Interactions
+
+```typescript
+// Click on traces
+cy.muiFirstTraceLink().click();                    // First trace in list
+cy.muiTraceLink('http-rbac-2').click();            // Specific service trace
+
+// Interact with span bars
+cy.muiFirstSpanBar().click();                      // First span bar
+cy.muiSpanBar('http-rbac-2').click();              // Specific service span
+cy.findByTestId('span-duration-bar').first().click(); // By test ID (multiple spans)
+```
+
+### Trace Attribute Validation
+
+```typescript
+// Single attribute validation
+cy.muiTraceAttribute('net.peer.ip', '1.2.3.4');
+cy.muiTraceAttribute('peer.service', 'telemetrygen-client');
+cy.muiTraceAttribute('k8s.container.name', 'telemetrygen', true); // Optional attribute
+
+// Custom validation with function
+cy.muiTraceAttribute('service.name', (text) => {
+  return ['http-rbac-1', 'http-rbac-2', 'grpc-rbac-1', 'grpc-rbac-2'].includes(text);
+}, false, 'TempoStack'); // Required attribute with logging
+
+// Bulk attribute validation (recommended for multiple attributes)
+cy.muiTraceAttributes({
+  'net.peer.ip': { value: '1.2.3.4' },
+  'peer.service': { value: 'telemetrygen-client' },
+  'k8s.container.name': { 
+    value: 'telemetrygen', 
+    optional: true 
+  },
+  'k8s.namespace.name': { 
+    value: (text) => text.startsWith('chainsaw-'),
+    optional: true 
+  },
+  'service.name': { 
+    value: ['http-rbac-1', 'http-rbac-2', 'grpc-rbac-1', 'grpc-rbac-2']
+  }
+}, 'Debug'); // Log prefix for debugging
+```
+
+### Complete Workflow Examples
+
+```typescript
+// Complete trace inspection workflow
+describe('Trace inspection', () => {
+  it('should navigate and validate trace details', () => {
+    // Navigate to traces page
+    cy.visit('/observe/traces');
+
+    // Select Tempo instance
+    cy.pfTypeahead('Select a Tempo instance').click();
+    cy.pfSelectMenuItem('chainsaw-rbac / simplst').click();
+
+    // Set time range
+    cy.pfMenuToggle('Last 30 minutes').click();
+    cy.pfSelectMenuItem('Last 1 hour').click();
+
+    // Filter by services
+    cy.pfMenuToggleByLabel('Multi typeahead checkbox').click();
+    cy.pfCheckMenuItem('http-rbac-1');
+    cy.pfCheckMenuItem('http-rbac-2');
+
+    // Click first trace
+    cy.muiFirstTraceLink().click();
+
+    // Click on span for details
+    cy.muiFirstSpanBar().click();
+
+    // Validate trace attributes efficiently
+    cy.muiTraceAttributes({
+      'net.peer.ip': { value: '1.2.3.4' },
+      'peer.service': { value: 'telemetrygen-client' },
+      'service.name': { 
+        value: (text) => text.includes('rbac')
+      }
+    });
+
+    // Navigate back
+    cy.pfBreadcrumb('Traces').click();
+  });
+});
+```
+
+## 🔄 PatternFly 5 & 6 Compatibility
+
+Our commands seamlessly support both PatternFly 5 and PatternFly 6 components:
+
+### Close Buttons
+
+```typescript
+// PatternFly 5 - Chip Group
+// <button aria-label="Close chip group" class="pf-v5-c-button pf-m-plain">
+cy.pfCloseButton('Close chip group').click();
+
+// PatternFly 6 - Label Group  
+// <button aria-label="Close label group" class="pf-v6-c-button pf-m-plain pf-m-no-padding">
+cy.pfCloseButton('Close label group').click();
+
+// Works with both versions automatically
+cy.pfCloseButton('Close').click();  // Finds any close button
+```
+
+### Menu Components
+
+```typescript
+// Both PF5 and PF6 menu structures supported
+cy.pfMenuToggle('Select Instance').click();     // Works with .pf-v5-c-menu-toggle or .pf-v6-c-menu-toggle
+cy.pfSelectMenuItem('tempo-stack').click();     // Works with .pf-v5-c-menu__item or .pf-v6-c-menu__item
+cy.pfCheckMenuItem('service-name');             // Handles both PF5/PF6 checkbox patterns
+```
+
+### Button Components
+
+```typescript
+// PatternFly button targeting (version-agnostic)
+cy.pfButton('Create Instance').click();         // Targets .pf-v5-c-button or .pf-v6-c-button
+cy.pfEmptyState().should('be.visible');         // Works with both .pf-v5-c-empty-state and .pf-v6-c-empty-state
+```
+
+### Key Benefits
+
+- ✅ **Automatic detection** - Commands work with both PF5 and PF6 automatically
+- ✅ **Future-proof** - Ready for PatternFly version upgrades
+- ✅ **Consistent API** - Same command syntax across versions
+- ✅ **Robust selectors** - Uses semantic attributes over version-specific classes
+
+## 🛡️ Defensive Programming Patterns
+
+### 1. Check Element Existence
+
+```typescript
+// Safe menu interaction
+cy.get('body').then(($body) => {
+  if ($body.find('.pf-v6-c-menu-toggle:contains("Actions")').length > 0) {
+    cy.pfMenuToggle('Actions').click();
+    if ($body.find('.pf-v6-c-menu__item:contains("Delete")').length > 0) {
+      cy.pfMenuItem('Delete').click();
+    }
+  }
+});
+```
+
+### 2. Wait for Stability
+
+```typescript
+// Wait for page load and React hydration
+cy.visit('/traces');
+cy.wait(2000); // Allow initial React state to settle
+
+// Perform interactions
+cy.pfEmptyState().should('be.visible');
+cy.pfButton('Create Instance').click();
+```
+
+### 3. Use Timeouts
+
+```typescript
+// Custom timeouts for slow-loading components
+cy.pfMenuToggle('Select Instance', { timeout: 15000 }).click();
+cy.pfMenuItem('TempoStack', { timeout: 10000 }).click();
+```
+
+## 🎯 Best Practices Summary
+
+1. **Add waits between complex interactions** to let React state stabilize
+2. **Use defensive checks** for dynamic content
+3. **Prefer direct PatternFly commands** over complex CSS selectors
+4. **Break complex operations** into smaller, testable steps
+5. **Handle uncaught exceptions** gracefully in support files
+6. **Use timeouts** for components that load asynchronously
+
+## 🔧 Troubleshooting
+
+If you encounter "e is not a function" errors:
+
+1. **Add `cy.wait(1000-2000)`** between interactions
+2. **Check if elements exist** before interacting
+3. **Use more specific selectors** instead of nth-child
+4. **Verify React components have finished rendering**
+5. **Review browser console** for additional React errors
+
+These patterns will make your tests more reliable and less prone to React state management issues.

+## Test Architecture & Best Practices
+
+### Custom Commands
+This project includes a comprehensive set of custom Cypress commands optimized for PatternFly and Material-UI components. These commands provide:
+
+- **Semantic selectors** instead of brittle CSS selectors
+- **Component-aware interactions** for PatternFly elements
+- **Bulk validation** for trace attributes (75% code reduction)
+- **Debug-friendly** commands with built-in logging
+
+### Key Command Categories
+
+#### PatternFly Components
+```typescript
+// Menu interactions
+cy.pfMenuToggle('Select Instance').click()
+cy.pfSelectMenuItem('tempo-stack').click()
+cy.pfCheckMenuItem('service-name')
+
+// Navigation
+cy.pfBreadcrumb('Traces').click()
+cy.pfButton('Create').click()
+cy.pfCloseButton('Close dialog').click()
+
+// Form controls
+cy.pfTypeahead('Select a Tempo instance').click()
+cy.pfMenuToggleByLabel('Multi typeahead').click()
 ```
+
+#### Trace & Observability
+```typescript
+// Trace interactions
+cy.muiFirstTraceLink().click()
+cy.muiTraceLink('http-service').click()
+cy.muiSpanBar('grpc-service').click()
+
+// Attribute validation (bulk)
+cy.muiTraceAttributes({
+  'service.name': { value: 'my-service' },
+  'net.peer.ip': { value: '1.2.3.4' },
+  'k8s.namespace': { value: 'test-ns', optional: true }
+})
+```
+
+### Debug Testing
+A debug test file (`dt-plugin-tests-debug.cy.ts.skip`) is available for rapid iteration without setup/teardown overhead. To use:
+
+```bash
+# Enable debug test
+mv tests/e2e/dt-plugin-tests-debug.cy.ts.skip tests/e2e/dt-plugin-tests-debug.cy.ts
+
+# Run debug test only
+npx cypress run --spec "e2e/dt-plugin-tests-debug.cy.ts"
+
+# Disable debug test
+mv tests/e2e/dt-plugin-tests-debug.cy.ts tests/e2e/dt-plugin-tests-debug.cy.ts.skip
+```
