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: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
