Migrate to Playwright

Interactive migration from Cypress or Selenium to Playwright with file-by-file conversion.

Input

$ARGUMENTS can be:

• "from cypress" — migrate Cypress test suite

• "from selenium" — migrate Selenium/WebDriver tests

• A file path: convert a specific test file

• Empty: auto-detect source framework

Steps

1. Detect Source Framework

Use Explore subagent to scan:

• cypress/ directory or cypress.config.ts → Cypress

• selenium , webdriver in package.json deps → Selenium

• .py test files with selenium imports → Selenium (Python)

2. Assess Migration Scope

Count files and categorize:

Migration Assessment:

• Total test files: X
• Cypress custom commands: Y
• Cypress fixtures: Z
• Estimated effort: [small|medium|large]

Size Files Approach

Small (1-10) Convert sequentially Direct conversion

Medium (11-30) Batch in groups of 5 Use sub-agents

Large (31+) Use /batch

Parallel conversion with /batch

3. Set Up Playwright (If Not Present)

Run /pw:init first if Playwright isn't configured.

4. Convert Files

For each file, apply the appropriate mapping:

Cypress → Playwright

Load cypress-mapping.md for complete reference.

Key translations:

cy.visit(url) → page.goto(url) cy.get(selector) → page.locator(selector) or page.getByRole(...) cy.contains(text) → page.getByText(text) cy.find(selector) → locator.locator(selector) cy.click() → locator.click() cy.type(text) → locator.fill(text) cy.should('be.visible') → expect(locator).toBeVisible() cy.should('have.text') → expect(locator).toHaveText(text) cy.intercept() → page.route() cy.wait('@alias') → page.waitForResponse() cy.fixture() → JSON import or test data file

Cypress custom commands → Playwright fixtures or helper functions Cypress plugins → Playwright config or fixtures before /beforeEach → test.beforeAll() / test.beforeEach()

Selenium → Playwright

Load selenium-mapping.md for complete reference.

Key translations:

driver.get(url) → page.goto(url) driver.findElement(By.id('x')) → page.locator('#x') or page.getByTestId('x') driver.findElement(By.css('.x')) → page.locator('.x') or page.getByRole(...) element.click() → locator.click() element.sendKeys(text) → locator.fill(text) element.getText() → locator.textContent() WebDriverWait + ExpectedConditions → expect(locator).toBeVisible() driver.switchTo().frame() → page.frameLocator() Actions → locator.hover(), locator.dragTo()

5. Upgrade Locators

During conversion, upgrade selectors to Playwright best practices:

• #id → getByTestId() or getByRole()

• .class → getByRole() or getByText()

• [data-testid] → getByTestId()

• XPath → role-based locators

6. Convert Custom Commands / Utilities

• Cypress custom commands → Playwright custom fixtures via test.extend()

• Selenium page objects → Playwright page objects (keep structure, update API)

• Shared helpers → TypeScript utility functions

7. Verify Each Converted File

After converting each file:

npx playwright test <converted-file> --reporter=list

Fix any compilation or runtime errors before moving to the next file.

8. Clean Up

After all files are converted:

• Remove Cypress/Selenium dependencies from package.json

• Remove old config files (cypress.config.ts , etc.)

• Update CI workflow to use Playwright

• Update README with new test commands

Ask user before deleting anything.

Output

• Conversion summary: files converted, total tests migrated

• Any tests that couldn't be auto-converted (manual intervention needed)

• Updated CI config

• Before/after comparison of test run results
