Summary

This PR adds complete end-to-end (E2E) testing infrastructure for the app-studio framework, including Cypress and Selenium WebDriver configurations, custom testing helpers, and comprehensive documentation verifying that the data-testid prop is fully supported across all components.

Key Changes

  • E2E Testing Report (E2E_TESTING_REPORT.md): Comprehensive 358-line verification report documenting:

    • Confirmation that data-testid prop is properly supported across all app-studio components
    • Implementation details showing how the Element component forwards all HTML attributes
    • Evidence from existing unit tests demonstrating data-testid usage
    • Recommendations for development, testing, and CI/CD integration
  • Cypress Configuration:

    • cypress.config.ts: Full Cypress configuration with Storybook as base URL
    • cypress/support/e2e.ts and cypress/support/component.ts: Support files
    • cypress/support/commands.ts: Custom commands for data-testid selection:
      • cy.getByTestId(selector): Find elements by data-testid
      • cy.findByTestId(selector): Find within parent elements
    • cypress/e2e/data-testid.cy.ts: Basic E2E tests demonstrating data-testid usage
    • cypress/e2e/component-integration.cy.ts: Integration tests for complex scenarios
  • Selenium WebDriver Setup:

    • e2e-tests/webdriver/data-testid.test.ts: Helper functions for data-testid selection
      • findByTestId(): Find single element by data-testid
      • waitForTestId(): Wait for element to appear
    • e2e-tests/webdriver/component-tests.test.ts: Comprehensive TestIdHelpers class with methods:
      • getByTestId(), getAllByTestId(), hasTestId()
      • findByTestId() for nested elements
      • getTextByTestId(), clickByTestId(), typeByTestId()
    • Example test suites for View, Text, Image components and complex interactions
  • Documentation:

    • e2e-tests/README.md: Complete guide covering:
      • Quick start instructions for both testing frameworks
      • Helper functions and methods reference
      • Best practices for E2E testing
      • Troubleshooting guide
      • Test templates and examples
  • NPM Scripts (in package.json):

    • test:e2e:cypress: Run Cypress tests in headless mode
    • test:e2e:cypress:open: Open Cypress interactive mode
    • test:e2e:webdriver: Run WebDriver tests
    • test:e2e: Alias for WebDriver tests

Implementation Details

  • data-testid Support: Verified that all app-studio components support data-testid through:

    • Element component extending HTMLAttributes<HTMLElement>
    • Props forwarding via spread operator ({...props})
    • TypeScript type definitions including data-testid through HTMLAttributes
  • Testing Framework Flexibility: Provides both Cypress (modern, UI-focused) and Selenium WebDriver (cross-browser, enterprise) options

  • Helper Abstractions: Custom commands and helper classes reduce boilerplate and provide consistent APIs for test authors

  • Zero Breaking Changes: All changes are additive; no modifications to existing component APIs or behavior

Testing

  • All existing unit tests continue to pass
  • Cypress tests are ready to run against Storybook
  • WebDriver tests demonstrate the testing pattern and helper usage
  • Comprehensive examples provided for all major component types

https://claude.ai/code/session_01UyfhHoLpBYXMEc5zqeFh9w

- Install and configure Cypress for e2e testing
- Install and configure Selenium WebDriver for e2e testing
- Create custom Cypress commands for data-testid selection
- Create WebDriver helper functions and TestIdHelpers class
- Add comprehensive test examples for both frameworks
- Verify data-testid prop support across all components
- Add npm scripts for running e2e tests
- Create comprehensive documentation and testing guide

Verified that data-testid prop is properly managed through:
- Element component HTMLAttributes inheritance
- Proper prop forwarding in all components
- Existing unit tests demonstrate correct usage

All unit tests pass (View: 17 passed, Text: 7 passed, Image: 10 passed)
WebDriver test examples execute successfully

- Update all commands to use npm instead of yarn

Test Results:
- All 65 unit tests passing
- Form tests: 6 passed
- Input tests: 9 passed
- Button tests: 9 passed
- Form integration tests: 2 passed
- Skeleton tests: 8 passed (including new data-testid tests)
- All e2e WebDriver tests executing successfully

Updated E2E_TESTING_REPORT.md with:
