Add unit tests for Quality Gates Panel components

[frankbria]

Problem

The Quality Gates Panel components ( and ) currently lack unit tests, which creates risk for regressions and makes it harder to validate business logic.

Scope

Add comprehensive unit tests for:

QualityGatesPanel.tsx (~180 lines)

• Task auto-selection logic - Verify first eligible task is selected correctly
• Gate status determination - Test getGateStatus() function with all status combinations
• Error handling - Test API failures display user-visible errors
• Loading states - Verify loading indicators appear/disappear correctly
• Empty state - Test behavior when no eligible tasks exist
• useRef optimization - Verify auto-selection only runs once

GateStatusIndicator.tsx (~60 lines)

• Icon rendering - Verify correct icons for each gate type
• Status badge styling - Test CSS classes for all status values
• Accessibility - Verify ARIA attributes are present
• Test IDs - Confirm data-testid attributes exist

qualityGateUtils.ts (~100 lines)

• getGateIcon() - Test all gate types return correct icons
• getGateName() - Test display names are formatted correctly
• getStatusClasses() - Verify CSS classes for all statuses
• getStatusIcon() - Test icons for all status values
• getSeverityClasses() - Verify severity badge styling

Target Coverage

Based on existing QualityGateStatus.test.tsx (618 lines of tests for similar component), aim for:

• Minimum 85% code coverage (per project standards)
• 100% function coverage for critical business logic
• Edge case testing for null/undefined states

Acceptance Criteria

• All components have test files in web-ui/__tests__/components/quality-gates/
• Test coverage >= 85% for all new components
• Critical business logic (getGateStatus) has 100% coverage
• Tests follow existing patterns from QualityGateStatus.test.tsx
• npm test passes with no failures

Estimated Effort

~3-4 hours (test writing, coverage verification)

Plan

Observations

The codebase has an existing file:web-ui/src/components/quality-gates/QualityGateStatus.tsx component (~320 lines) with comprehensive tests in file:web-ui/__tests__/components/QualityGateStatus.test.tsx (618 lines). The Dashboard has a commented-out Quality Gates Panel (lines 438-445) that's disabled because it requires a taskId. The issue requests creating three new components/utilities by extracting and refactoring existing code: QualityGatesPanel (task selection wrapper), GateStatusIndicator (reusable status badges), and qualityGateUtils (utility functions currently inline in QualityGateStatus). The project uses Jest with React Testing Library, Next.js, TypeScript, and Tailwind CSS.

Approach

The implementation will follow a refactoring approach: extract utility functions from QualityGateStatus.tsx into qualityGateUtils.ts, create a reusable GateStatusIndicator component for status badges, and build a QualityGatesPanel wrapper that handles task selection logic. All three will have comprehensive unit tests following the patterns established in QualityGateStatus.test.tsx. Tests will use Jest mocks for API calls, React Testing Library for component rendering, and aim for 85%+ coverage with 100% coverage for critical business logic. The modular design will enable the Dashboard to integrate the panel without requiring manual task selection.

Implementation Steps

1. Create Utility Functions Module

File: file:web-ui/src/utils/qualityGateUtils.ts

Extract the following utility functions from file:web-ui/src/components/quality-gates/QualityGateStatus.tsx:

• getGateIcon(gate: QualityGateType): string - Maps gate types to emoji icons (lines 121-136)
• getGateName(gate: QualityGateType): string - Formats gate type names for display (e.g., "type_check" → "Type Check")
• getStatusClasses(status: QualityGateStatusValue): string - Returns Tailwind CSS classes for status badges (lines 89-102)
• getStatusIcon(status: QualityGateStatusValue): string - Maps status values to emoji icons (lines 139-152)
• getSeverityClasses(severity: QualityGateSeverity): string - Returns Tailwind CSS classes for severity badges (lines 105-118)

Export all functions with proper TypeScript types from file:web-ui/src/types/qualityGates.ts.

2. Create GateStatusIndicator Component

File: file:web-ui/src/components/quality-gates/GateStatusIndicator.tsx

Create a reusable component that displays status badges with icons:

Props Interface:

interface GateStatusIndicatorProps {
  status: QualityGateStatusValue;
  gate?: QualityGateType;
  severity?: QualityGateSeverity;
  requiresApproval?: boolean;
  className?: string;
}

Responsibilities:

• Render status badge with appropriate icon using getStatusIcon() and getStatusClasses()
• Optionally display gate type icon using getGateIcon()
• Optionally display severity badge using getSeverityClasses()
• Show human approval badge when requiresApproval is true
• Include data-testid attributes for testing
• Apply ARIA attributes for accessibility (role="status", aria-label)

3. Create QualityGatesPanel Component

File: file:web-ui/src/components/quality-gates/QualityGatesPanel.tsx

Create a panel component that wraps QualityGateStatus with task selection logic:

Props Interface:

interface QualityGatesPanelProps {
  projectId: number;
  autoRefresh?: boolean;
  refreshInterval?: number;
}

Key Features:

• Task Auto-Selection Logic:

  • Fetch tasks for the project using SWR or existing API
  • Filter for eligible tasks (status: 'completed' or 'in_progress')
  • Auto-select first eligible task on mount
  • Use useRef to ensure selection only runs once (prevent re-selection on re-renders)

• Gate Status Determination:

  • Implement getGateStatus() function that aggregates status across all tasks
  • Return overall status: 'passed' (all passed), 'failed' (any failed), 'running' (any running), 'pending' (all pending)
  • Handle edge cases: no tasks, no quality gate data

• UI Structure:

  • Header with title "✅ Quality Gates" and overall status indicator
  • Task selector dropdown (if multiple eligible tasks exist)
  • Render <QualityGateStatus taskId={selectedTaskId} /> when task is selected
  • Empty state message when no eligible tasks exist
  • Error boundary for API failures

• Loading & Error States:

  • Show loading spinner while fetching tasks
  • Display user-visible error messages on API failures
  • Gracefully handle missing or invalid data

4. Refactor QualityGateStatus Component

File: file:web-ui/src/components/quality-gates/QualityGateStatus.tsx

Update the existing component to use the extracted utilities:

• Replace inline utility functions with imports from qualityGateUtils.ts
• Replace status badge rendering with <GateStatusIndicator /> component
• Maintain all existing functionality and props
• Ensure backward compatibility with existing tests

5. Create Unit Tests for qualityGateUtils

File: file:web-ui/__tests__/utils/qualityGateUtils.test.ts

Test all utility functions with comprehensive coverage:

Test Suites:

• getGateIcon():

  • Test all gate types: 'tests', 'type_check', 'coverage', 'code_review', 'linting'
  • Verify default icon for unknown gate types
  • Edge case: null/undefined input

• getGateName():

  • Test formatting for all gate types
  • Verify underscore replacement and capitalization
  • Edge case: empty string, special characters

• getStatusClasses():

  • Test CSS classes for all status values: 'passed', 'failed', 'running', 'pending', null
  • Verify Tailwind classes include background, text, and border colors
  • Edge case: undefined status returns default gray classes

• getStatusIcon():

  • Test icons for all status values
  • Verify default icon for unknown status
  • Edge case: null/undefined input

• getSeverityClasses():

  • Test CSS classes for all severity levels: 'critical', 'high', 'medium', 'low'
  • Verify color coding matches severity (red for critical, orange for high, etc.)
  • Edge case: unknown severity returns default gray classes

Coverage Target: 100% function coverage (pure utility functions)

6. Create Unit Tests for GateStatusIndicator

File: file:web-ui/__tests__/components/quality-gates/GateStatusIndicator.test.tsx

Follow patterns from file:web-ui/__tests__/components/QualityGateStatus.test.tsx:

Test Suites:

• Icon Rendering:

  • Verify correct status icon displayed for each status value
  • Verify gate icon displayed when gate prop provided
  • Test icon not displayed when gate prop omitted

• Status Badge Styling:

  • Test CSS classes applied for all status values
  • Verify badge contains correct text content
  • Test custom className prop is applied

• Severity Badge:

  • Test severity badge displayed when severity prop provided
  • Verify correct CSS classes for each severity level
  • Test severity badge not displayed when prop omitted

• Human Approval Badge:

  • Test approval badge displayed when requiresApproval={true}
  • Verify badge contains "Requires Approval" text
  • Test badge not displayed when requiresApproval={false}

• Accessibility:

  • Verify role="status" attribute present
  • Test aria-label describes status correctly
  • Verify screen reader text is meaningful

• Test IDs:

  • Confirm data-testid="gate-status-indicator" exists
  • Test child elements have appropriate test IDs

Coverage Target: 85%+ code coverage

7. Create Unit Tests for QualityGatesPanel

  • Edge case: no eligible tasks available

• Gate Status Determination:

  • Test getGateStatus() with all tasks passed → returns 'passed'
  • Test with any task failed → returns 'failed'
  • Test with any task running → returns 'running'
  • Test with all tasks pending → returns 'pending'
  • Edge case: empty task list, mixed statuses

• Loading States:

  • Test loading spinner displayed while fetching tasks
  • Verify loading indicator disappears after data loads
  • Test loading state for quality gate data

• Error Handling:

  • Test API failure displays user-visible error message
  • Verify error boundary catches component errors
  • Test retry mechanism on error
  • Edge case: network timeout, 404 response

• Empty State:

  • Test message displayed when no eligible tasks exist
  • Verify empty state shows helpful guidance
  • Test empty state styling and layout

1. Mock API calls using jest.mock() for @/api/qualityGates
2. Use React Testing Library utilities: render, screen, waitFor, fireEvent
3. Test user interactions with fireEvent.click() for buttons
4. Verify async behavior with waitFor() for API responses
5. Test accessibility with getByRole() and ARIA attributes
6. Mock timers for auto-refresh functionality using jest.useFakeTimers()
7. Test edge cases including null/undefined, empty arrays, error states
8. Use descriptive test names following pattern: "should [expected behavior] when [condition]"
9. Group related tests using nested describe() blocks
10. Clear mocks in beforeEach() to ensure test isolation

## Testing Patterns to Follow

Based on `file:web-ui/__tests__/components/QualityGateStatus.test.tsx`:

1. **Mock API calls** using `jest.mock()` for `@/api/qualityGates`
2. **Use React Testing Library** utilities: `render`, `screen`, `waitFor`, `fireEvent`
3. **Test user interactions** with `fireEvent.click()` for buttons
4. **Verify async behavior** with `waitFor()` for API responses
5. **Test accessibility** with `getByRole()` and ARIA attributes
