<objective>
Create Jest unit tests for JKSessionSettingsModal component covering all three requirements: rendering with props, save payload transformation, and loading state behavior.

Purpose: Enable confident changes to Session Settings modal by having automated test coverage for critical paths
Output: Test file with passing tests for UNIT-01, UNIT-02, UNIT-03
</objective>

<tasks>

<task type="auto">
  <name>Task 1: Create test file with setup and mocks</name>
  <files>jam-ui/src/components/client/__tests__/JKSessionSettingsModal.test.js</files>
  <action>
Create the __tests__ directory if needed and test file with proper setup:

1. Create directory structure:
   - `jam-ui/src/components/client/__tests__/` (may already exist)

2. Set up test file with required imports:
   ```javascript
   import React from 'react';
   import { render, screen, fireEvent } from '@testing-library/react';
   import JKSessionSettingsModal from '../JKSessionSettingsModal';
   import { SESSION_PRIVACY_MAP } from '../../../helpers/globals.js';
   ```

3. Mock react-i18next (required because component uses useTranslation):
   ```javascript
   jest.mock('react-i18next', () => ({
     useTranslation: () => ({
       t: (key) => {
         const translations = {
           'new.privacy_opt_public': 'Public',
           'new.privacy_opt_private_invite': 'Private (Invite Only)',
           'new.privacy_opt_private_approve': 'Private (Approval Required)'
         };
         return translations[key] || key;
       }
     })
   }));
   ```

4. Create helper function for rendering component:
   ```javascript
   const renderModal = (props = {}) => {
     const defaultProps = {
       isOpen: true,
       toggle: jest.fn(),
       currentSession: {
         privacy: SESSION_PRIVACY_MAP.private_approve,
         description: 'Test session description'
       },
       onSave: jest.fn(),
       loading: false
     };
     return render(<JKSessionSettingsModal {...defaultProps} {...props} />);
   };
   ```

5. Add describe block shell:
   ```javascript
   describe('JKSessionSettingsModal', () => {
     // Tests will be added in next task
   });
   ```
  </action>
  <verify>
File exists at jam-ui/src/components/client/__tests__/JKSessionSettingsModal.test.js
File compiles without syntax errors: `cd jam-ui && npm run test:unit -- --testPathPattern=JKSessionSettingsModal --passWithNoTests`
  </verify>
  <done>Test file created with all setup code, mocks, and helper functions in place</done>
</task>

<task type="auto">
  <name>Task 2: Write tests for all three requirements</name>
  <files>jam-ui/src/components/client/__tests__/JKSessionSettingsModal.test.js</files>
  <action>
Add test cases inside the describe block for each requirement:

**UNIT-01: Modal renders with currentSession props**
```javascript
describe('rendering with currentSession props (UNIT-01)', () => {
  test('displays privacy value from currentSession', () => {
    renderModal({
      currentSession: {
        privacy: SESSION_PRIVACY_MAP.public,
        description: ''
      }
    });

    const privacySelect = screen.getByTestId('session-privacy');
    expect(privacySelect.value).toBe(String(SESSION_PRIVACY_MAP.public));
  });

  test('displays description value from currentSession', () => {
    const testDescription = 'My test session description';
    renderModal({
      currentSession: {
        privacy: SESSION_PRIVACY_MAP.private_approve,
        description: testDescription
      }
    });

    const descriptionInput = screen.getByRole('textbox');
    expect(descriptionInput.value).toBe(testDescription);
  });

  test('renders modal title', () => {
    renderModal();
    expect(screen.getByText('Session Settings')).toBeInTheDocument();
  });
});
```

**UNIT-02: Save button calls onSave with correct payload**
```javascript
describe('save functionality (UNIT-02)', () => {
  test('calls onSave with privacy and description when save clicked', () => {
    const mockOnSave = jest.fn();
    renderModal({
      currentSession: {
        privacy: SESSION_PRIVACY_MAP.public,
        description: 'Original description'
      },
      onSave: mockOnSave
    });

    const saveButton = screen.getByRole('button', { name: /save/i });
    fireEvent.click(saveButton);

    expect(mockOnSave).toHaveBeenCalledTimes(1);
    expect(mockOnSave).toHaveBeenCalledWith({
      privacy: String(SESSION_PRIVACY_MAP.public),
      description: 'Original description'
    });
  });

  test('calls onSave with updated values after user changes', () => {
    const mockOnSave = jest.fn();
    renderModal({
      currentSession: {
        privacy: SESSION_PRIVACY_MAP.private_approve,
        description: ''
      },
      onSave: mockOnSave
    });

    // Change privacy
    const privacySelect = screen.getByTestId('session-privacy');
    fireEvent.change(privacySelect, { target: { value: SESSION_PRIVACY_MAP.public } });

    // Change description
    const descriptionInput = screen.getByRole('textbox');
    fireEvent.change(descriptionInput, { target: { value: 'New description' } });

    // Click save
    const saveButton = screen.getByRole('button', { name: /save/i });
    fireEvent.click(saveButton);

    expect(mockOnSave).toHaveBeenCalledWith({
      privacy: String(SESSION_PRIVACY_MAP.public),
      description: 'New description'
    });
  });
});
```

**UNIT-03: Loading state disables form interactions**
```javascript
describe('loading state (UNIT-03)', () => {
  test('disables save button when loading', () => {
    renderModal({ loading: true });

    const saveButton = screen.getByRole('button', { name: /saving/i });
    expect(saveButton).toBeDisabled();
  });

  test('disables cancel button when loading', () => {
    renderModal({ loading: true });

    const cancelButton = screen.getByRole('button', { name: /cancel/i });
    expect(cancelButton).toBeDisabled();
  });

  test('disables description textarea when loading', () => {
    renderModal({ loading: true });

    const descriptionInput = screen.getByRole('textbox');
    expect(descriptionInput).toBeDisabled();
  });

  test('shows "Saving..." text on save button when loading', () => {
    renderModal({ loading: true });

    expect(screen.getByRole('button', { name: /saving/i })).toBeInTheDocument();
  });
});
```

Note: The privacy select dropdown is NOT disabled when loading (based on component code review - only description textarea has `disabled={loading}`). The tests reflect actual component behavior.

Run tests: `cd jam-ui && npm run test:unit -- --testPathPattern=JKSessionSettingsModal`
All tests pass (exit code 0)
  </verify>
  <done>
All three requirements covered with passing tests:
- UNIT-01: 3 tests for rendering (privacy, description, title)
- UNIT-02: 2 tests for save functionality (initial values, updated values)
- UNIT-03: 4 tests for loading state (save disabled, cancel disabled, textarea disabled, button text)

<task type="auto">
  <name>Task 3: Verify full test suite and clean up</name>
  <files>jam-ui/src/components/client/__tests__/JKSessionSettingsModal.test.js</files>
  <action>
1. Run full unit test suite to ensure no regressions:
   ```bash
   cd jam-ui && npm run test:unit
   ```

2. Verify test count matches expectations (9 tests total: 3 + 2 + 4)

3. Check test output shows all test names correctly grouped:
   - JKSessionSettingsModal
     - rendering with currentSession props (UNIT-01)
     - save functionality (UNIT-02)
     - loading state (UNIT-03)

4. If any tests fail, debug and fix:
   - Check if component behavior differs from expectations
   - Adjust test assertions to match actual component behavior
   - Do NOT modify the component - only fix test expectations

5. Add any missing edge case tests if time permits:
   - Empty description handling
   - Default privacy value when currentSession.privacy is undefined
  </action>
  <verify>
`cd jam-ui && npm run test:unit` passes with 0 failures
Test file has proper structure with requirement labels in describe blocks
  </verify>
  <done>
All unit tests pass, test file is complete and properly structured with requirement traceability (UNIT-01, UNIT-02, UNIT-03)
