Device Users Tests Migration Summary

Overview

Successfully migrated all Device Users end-to-end tests from WebDriverIO (wdio) to Cypress as part of the larger wdio-to-Cypress migration effort.

Migration Statistics

Test Files Migrated

  • ✅ device-users.add.spec.ts → device-users.add.spec.cy.ts (6 tests)
  • ✅ device-users.edit.spec.ts → device-users.edit.spec.cy.ts (4 tests)
  • ✅ device-users.delete.spec.ts → device-users.delete.spec.cy.ts (2 tests)

Total: 12 test scenarios successfully migrated

File Locations

  • Original wdio tests: eform-client/e2e/Tests/device-users/
  • New Cypress tests: eform-client/cypress/e2e/d/
  • Shared Page Object: eform-client/cypress/e2e/DeviceUsers.page.ts (existing, no changes needed)

Test Coverage Comparison

device-users.add.spec.cy.ts (6 tests)

All original test scenarios preserved:

  1. ✅ Should add new device user with first name and last name

    • Creates a device user with both required fields
    • Verifies row count increases by 1
    • Validates first name and last name are correctly saved

  2. ✅ Should NOT add device user with only first name (validation)

    • Opens create modal
    • Enters only first name
    • Verifies save button is disabled
    • Cancels operation

  3. ✅ Should NOT add device user with only last name (validation)

    • Opens create modal
    • Enters only last name
    • Verifies save button is disabled
    • Cancels operation

  4. ✅ Should NOT add device user without first and last names (validation)

    • Opens create modal
    • Leaves both fields empty
    • Verifies save button is disabled
    • Cancels operation

  5. ✅ Should NOT create user if cancel was clicked

    • Opens create modal
    • Clicks cancel
    • Verifies row count remains unchanged

  6. ✅ Should clean up created test data

    • Finds the test user created in test #1
    • Deletes it
    • Verifies row count returns to original value

device-users.edit.spec.cy.ts (4 tests)

All original test scenarios preserved:

  1. ✅ Should edit device user's first name

    • Creates a test user in before hook
    • Edits only the first name
    • Verifies first name changed, last name unchanged

  2. ✅ Should edit device user's last name

    • Edits only the last name
    • Verifies last name changed, first name unchanged

  3. ✅ Should edit both first name and last name

    • Edits both fields simultaneously
    • Verifies both fields updated correctly

  4. ✅ Should not change first name and last name if cancel was clicked

    • Opens edit modal
    • Changes both fields
    • Clicks cancel
    • Verifies no changes were saved

device-users.delete.spec.cy.ts (2 tests)

All original test scenarios preserved:

  1. ✅ Should not delete device user if cancel was clicked

    • Creates a test user in before hook
    • Clicks delete button
    • Clicks cancel on confirmation modal
    • Verifies user still exists and count unchanged

  2. ✅ Should delete device user successfully

    • Clicks delete button
    • Confirms deletion
    • Verifies user is deleted and count decreased by 1

Technical Implementation Details

Cypress Patterns Used

  1. Test Structure

    • Used describe blocks to group related tests
    • Used before hooks for test setup (login, navigation, test data creation)
    • Used arrow functions () => instead of async () => (Cypress handles async automatically)

  2. Element Selection

    • Migrated from $('#selector') to cy.get('#selector')
    • Used chainable assertions: .should('be.visible'), .should('be.enabled'), .should('be.disabled')

  3. Waiting Strategies

    • Removed explicit browser.pause() calls
    • Used cy.get('#spinner-animation').should('not.exist') to wait for loading
    • Leveraged Cypress's built-in retry-ability for element assertions

  4. Assertions

    • Migrated from expect(actual).equal(expected) to expect(actual).to.equal(expected)
    • Used Chai assertions as imported: import { expect } from 'chai';

  5. Page Object Usage

    • Reused existing DeviceUsers.page.ts Cypress page object
    • Leveraged deviceUsersPage.Navbar.goToDeviceUsersPage() for navigation
    • Used deviceUsersPage.rowNum() for counting table rows

  6. Test Data Generation

    • Used existing generateRandmString() helper function from helper-functions.ts
    • Used Guid.create().toString() for unique identifiers (matching wdio approach)

Code Quality

  • ✅ All tests pass ESLint validation
  • ✅ Code follows existing Cypress test patterns in the repository
  • ✅ Proper use of TypeScript types and imports
  • ✅ Clear and descriptive test names
  • ✅ Inline comments for complex operations
  • ✅ Consistent formatting and style

CI/CD Integration

GitHub Actions Configuration

  • Tests will run automatically in the existing CI/CD pipeline
  • Located in matrix test group 'd': .github/workflows/dotnet-core-pr.yml
  • Execution command: cypress/e2e/d/* (runs all tests in directory d)

Original wdio Configuration

  • Original tests remain in wdio-headless-step2f.conf.ts
  • Tests will continue to run in wdio until full migration is complete
  • Can be removed after Cypress tests are verified in CI/CD

Verification Checklist

  • ✅ All 12 test scenarios migrated and match original functionality
  • ✅ Tests follow Cypress best practices and patterns
  • ✅ ESLint validation passed with no errors
  • ✅ TypeScript compilation successful
  • ✅ Test file naming convention followed (*.spec.cy.ts)
  • ✅ Tests organized in correct directory (cypress/e2e/d/)
  • ✅ Page objects properly reused
  • ✅ WDIO_TO_CYPRESS_MIGRATION.md updated
  • ✅ Migration progress tracked (25/38 total tests, +10.7%)

Key Differences: wdio vs Cypress

Aspect wdio Cypress
Async/Await Required (async/await) Not needed (automatic)
Element Selection $('#id') or await $('#id') cy.get('#id')
Waits element.waitForDisplayed() .should('be.visible')
Browser Pause browser.pause(500) cy.wait(500) (minimal use)
Assertions expect(a).equal(b) expect(a).to.equal(b)
Test Setup before(async () => {}) before(() => {})

Benefits of Cypress Migration

  1. Faster Test Execution: Cypress tests typically run faster than wdio
  2. Better Debugging: Built-in time-travel debugging and screenshots
  3. Improved Reliability: Automatic waiting and retry logic reduces flakiness
  4. Modern Tooling: Better IDE support and developer experience
  5. Easier Maintenance: Simpler syntax and less boilerplate code

Future Work

  • Original wdio tests can be removed once all tests are migrated
  • Consider adding more comprehensive error scenarios
  • Potential for additional API mocking with cy.intercept()
