Playwright Generate Test

Test Generation with Playwright MCP

Generate a Playwright TypeScript test by first interacting with the real application via the Playwright MCP server, then producing a verified test file.

Workflow

1. Get the scenario — If not provided, ask the user to describe the test scenario (URL, steps, expected outcomes)
2. Navigate to the application — Use browser_navigate to load the target page
3. Execute the scenario step by step — Walk through each interaction using MCP tools:
   • browser_click for clicks
   • browser_type for text input
   • browser_select_option for dropdowns
   • browser_snapshot to observe state between steps
4. Capture locators and assertions — Note the actual locators and expected states observed during execution
5. Generate the test — Write a Playwright TypeScript test using @playwright/test based on the real interactions observed:

import { test, expect } from '@playwright/test';

test('descriptive test name', async ({ page }) => {
  await page.goto('URL');
  // Steps based on actual MCP interactions
});

6. Save the test — Write the file to the project's tests directory
7. Run and iterate — Execute the test and fix any failures until it passes

Guidelines

• Never generate test code before completing the MCP interaction steps
• Use stable locators observed during exploration (data-testid > getByRole > getByText)
• Add meaningful assertions after key interactions
• Keep tests focused on a single user flow
• Use descriptive test names that explain the scenario
