Testing Guide for Table Manager and Column Manager Features

This document describes the test coverage for the newly implemented Table Manager and Column Manager features in the PostgreSQL Admin Panel.

Test Files

Integration Tests (Playwright API Tests)

1. tests/integration/TableManager.spec.ts

Tests for the Table Management API endpoints (/api/admin/table-manage):

Create Table Tests:

• ✅ Creates new table with proper column definitions
• ✅ Validates table name is required
• ✅ Validates at least one column is required
• ✅ Rejects invalid table names (SQL injection prevention)
• ✅ Requires authentication for all operations

Drop Table Tests:

• ✅ Validates table name is required
• ✅ Rejects invalid table names
• ✅ Requires authentication

Test Coverage:

• Input validation
• SQL injection prevention
• Authentication/authorization
• Error handling

2. tests/integration/ColumnManager.spec.ts

Tests for the Column Management API endpoints (/api/admin/column-manage):

Add Column Tests:

• ✅ Requires authentication
• ✅ Validates all required fields (tableName, columnName, dataType)
• ✅ Rejects invalid table names
• ✅ Rejects invalid column names

Modify Column Tests:

• ✅ Requires authentication
• ✅ Validates required fields
• ✅ Rejects invalid identifiers

Drop Column Tests:

• ✅ Requires authentication
• ✅ Validates required fields
• ✅ Rejects invalid identifiers

Test Coverage:

• Input validation
• SQL injection prevention
• Authentication/authorization
• Error handling for all CRUD operations

End-to-End Tests (Playwright UI Tests)

3. tests/e2e/AdminDashboard.e2e.ts

Tests for the admin dashboard UI and user flows:

Navigation Tests:

• ✅ Redirects to login when not authenticated
• ✅ Displays login page with proper form elements

Table Manager UI Tests:

• 🔄 Display Table Manager tab (requires auth - skipped)
• 🔄 Open create table dialog (requires auth - skipped)

Column Manager UI Tests:

• 🔄 Display Column Manager tab (requires auth - skipped)
• 🔄 Show table selector (requires auth - skipped)

Security Tests:

• ✅ Blocks admin API access without authentication
• ✅ Blocks table management without authentication
• ✅ Blocks column management without authentication

Note: Some UI tests are skipped because they require an authenticated session. These can be enabled when a test authentication mechanism is implemented.

Running Tests

Run All Tests

npm test              # Run Vitest unit tests
npm run test:e2e      # Run Playwright E2E tests

Run Specific Test Files

# Run integration tests only
npx playwright test tests/integration/

# Run specific test file
npx playwright test tests/integration/TableManager.spec.ts

# Run e2e tests only
npx playwright test tests/e2e/

Run Tests in Watch Mode

npm run test -- --watch        # Vitest watch mode

Run Tests with UI

npx playwright test --ui       # Playwright UI mode

Test Structure

Integration Tests Pattern

test.describe('Feature Name', () => {
  test.describe('Specific Functionality', () => {
    test('should do something specific', async ({ page }) => {
      const response = await page.request.post('/api/endpoint', {
        data: { /* test data */ },
      });
      
      expect(response.status()).toBe(expectedStatus);
    });
  });
});

E2E Tests Pattern

test.describe('UI Feature', () => {
  test('should display correct elements', async ({ page }) => {
    await page.goto('/path');
    
    await expect(page.getByRole('button', { name: /action/i })).toBeVisible();
  });
});

Security Testing

All tests verify that:

1. Authentication is required for admin operations
2. Input validation prevents SQL injection
3. Invalid identifiers are rejected (table/column names)
4. Error messages don't leak sensitive information

Feature: Constraint Management Tests

Integration Tests (Playwright API Tests)

1. tests/integration/ConstraintManager.spec.ts

Tests for the Constraint Management API endpoints (/api/admin/constraints):

List Constraints Tests:

• ✅ Rejects list without authentication
• ✅ Rejects list without table name
• ✅ Rejects list with invalid table name

Add Constraint Tests:

• ✅ Rejects add without authentication
• ✅ Rejects add without required fields
• ✅ Rejects add with invalid table name
• ✅ Rejects UNIQUE constraint without column name
• ✅ Rejects CHECK constraint without expression
• ✅ Rejects CHECK constraint with dangerous expression (SQL injection prevention)
• ✅ Rejects unsupported constraint types

Drop Constraint Tests:

• ✅ Rejects drop without authentication
• ✅ Rejects drop without required fields
• ✅ Rejects drop with invalid identifiers

Test Coverage:

• Input validation
• SQL injection prevention
• Authentication/authorization
• Error handling for all CRUD operations
• Support for UNIQUE and CHECK constraints

Unit Tests

2. src/utils/featureConfig.test.ts

Tests for the constraint types configuration:

Constraint Types Tests:

• ✅ Returns array of constraint types
• ✅ Validates constraint type properties
• ✅ Includes UNIQUE constraint type with correct flags
• ✅ Includes CHECK constraint type with correct flags

Future Test Improvements

Short Term

• Add authenticated session fixture for UI tests
• Enable skipped UI tests with proper authentication
• Add tests for success scenarios with valid credentials
• Test visual column builder interactions
• Test schema refresh after operations

Medium Term

• Add performance tests for large table operations
• Add accessibility tests (a11y)
• Add visual regression tests
• Test error recovery and rollback scenarios
• Add tests for concurrent operations

Long Term

• Integration tests with real PostgreSQL database
• Load testing for multiple simultaneous users
• Cross-browser compatibility tests
• Mobile responsiveness tests

Continuous Integration

Tests are designed to run in CI/CD pipelines:

# Example CI configuration
- name: Run Integration Tests
  run: npm run test:e2e -- tests/integration/

- name: Run E2E Tests
  run: npm run test:e2e -- tests/e2e/

Test Data Management

• Tests use faker library for generating random test data
• Each test run creates unique table names to avoid conflicts
• Tests validate authentication is required, so they expect 401 responses when not authenticated
• No database cleanup is required for API validation tests

Contributing

When adding new features:

1. Add integration tests for new API endpoints
2. Add E2E tests for new UI components
3. Ensure security tests cover authentication
4. Update this documentation with new test coverage
5. Run all tests before submitting PR
