Writing Performance Tests:

// Start a performance measurement
cy.startMeasurement("my-operation");

// Perform the operation to measure
cy.get(".some-element").click();

// End measurement and record result
cy.endMeasurement("my-operation", "user-interaction");

import {
  measureWidgetRenderPerformance,
  measureInteractionPerformance,
} from "../../support/test-patterns";

// Measure widget rendering performance
measureWidgetRenderPerformance('[data-testid="my-widget"]');

// Measure user interaction performance
measureInteractionPerformance(".button", "click");

it("meets performance requirements", () => {
  cy.startMeasurement("my-operation");

  // Operation to test
  cy.setSecurityLevels("High", "High", "High");

  cy.endMeasurement("my-operation", "security-level-change").then(
    (duration) => {
      // Assert against requirements
      cy.assertPerformance("my-operation", duration, {
        warning: 300, // Warning threshold in ms
        error: 600, // Error threshold in ms
      });
    }
  );
});

it("meets performance requirements", () => {
  cy.startMeasurement("my-operation");

  // Operation to test
  cy.setSecurityLevels("High", "High", "High");

  cy.endMeasurement("my-operation", "security-level-change").then(
    (duration) => {
      // Assert against requirements
      cy.assertPerformance("my-operation", duration, {
        warning: 300, // Warning threshold in ms
        error: 600, // Error threshold in ms
      });
    }
  );
});

Chrome DevTools Performance Analysis:

1. Open Chrome DevTools (F12)
2. Navigate to Performance tab
3. Start recording
4. Perform user actions (select security levels, view widgets)
5. Stop recording and analyze:
   • JavaScript execution time
   • Rendering time
   • Layout shifts
   • Memory usage
   • Long tasks (>50ms)

Performance Insights:

• Use Lighthouse tab in DevTools for quick audits
• Check Network tab for asset loading waterfall
• Use Coverage tab to identify unused CSS/JS
• Profile with CPU throttling (4x slowdown) for mobile simulation

⚠️ Local E2E performance report generation is not yet implemented. The documentation for cypress/reports/performance/performance-report.json and performance-dashboard.html is a placeholder for a planned feature.

Note: The file cypress/config/performance-baseline.ts and the baseline configurations (DEV_BASELINE, PROD_BASELINE, CI_BASELINE) are not yet implemented. The following describes a proposed feature for future releases.

Planned Baseline Configurations:

1. DEV_BASELINE: Lenient thresholds for development environments
2. PROD_BASELINE: Stricter thresholds for production environments
3. CI_BASELINE: Adjusted thresholds for CI environments

Proposed Example Configuration:

// (Planned) Modify baseline for custom operations
// DEV_BASELINE.operations["my-custom-operation"] = {
//   warning: 300,
//   error: 800,
// };

1. Inconsistent Metrics

• Issue: Performance varies significantly between runs
• Solution: Run tests multiple times to establish stable averages
• Action: Use Lighthouse median scores (run 3+ times)

2. CI Performance Variations

• Issue: CI environments have variable performance
• Solution: Adjust thresholds for CI baseline (use CI_BASELINE)
• Action: Add CPU throttling simulation for consistency

3. Resource Contention

• Issue: Local tests affected by other applications
• Solution: Close other applications during performance testing
• Action: Use dedicated testing environment or container

If widgets fail to meet performance requirements:

1. Check for Unnecessary Re-renders

   • Use React DevTools Profiler
   • Look for missing dependency arrays in hooks
   • Add proper memoization with useMemo() and useCallback()

2. Optimize Expensive Calculations

   • Move expensive operations outside render functions
   • Cache results of complex calculations
   • Consider web workers for CPU-intensive operations

3. Improve DOM Efficiency

   • Minimize DOM manipulations
   • Use virtualization for large lists
   • Verify efficient DOM access patterns

4. Reduce Bundle Size

   • Check bundle analysis reports
   • Implement code splitting for large components
   • Lazy load non-critical widgets

5. Use Profiling Tools

   • Run Chrome Performance profiler to identify bottlenecks
   • Use Cypress performance monitoring with detailed timing
   • Generate flamegraphs to visualize call stacks
