Playwright Test Generator from AI Test Cases

How Does the Playwright Test Generator Work?

QAMind calls an MCP server running on port 3100 on the user's local workstation. The MCP server receives approved test cases and converts each one into a Playwright test block. The generator groups test cases by shared prerequisites and produces merged .spec.ts files.

The MCP server runs alongside Playwright on the user's workstation. QAMind provides setup scripts for Windows and macOS. The local runner setup dialog in the app guides users through installation in 4 steps.

What is an MCP server in QAMind's architecture?

An MCP server is a local process that QAMind calls to execute tool-based operations on the user's machine. QAMind's MCP server handles 2 operations: generating Playwright scripts from test cases and executing those scripts on the local Playwright installation. The server runs on port 3100 and communicates with QAMind's cloud app over the user's private network.

Script generation steps:

1. 01Install the MCP server and Playwright on your workstation using the provided setup script.
2. 02Start the MCP server so QAMind can reach it on port 3100.
3. 03Select an approved test suite in QAMind's script generator view.
4. 04Click "Generate Scripts" to convert the test cases to Playwright files.
5. 05Click "Run" to execute the scripts and record results as a test run.

What Does the Playwright Generator Produce?

The generator produces standard Playwright .spec.ts files using @playwright/test. Each file contains test blocks that correspond to approved test case steps. Scripts use Playwright's built-in auto-wait and locator APIs.

Test cases with shared prerequisites merge into a single spec file. Test cases without shared prerequisites produce individual spec files. The grouping logic reduces test duplication and improves execution efficiency.

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

test('User can log in with valid credentials', async ({ page }) => {
  await page.goto('/login');
  await page.locator('[data-testid="email"]').fill('user@example.com');
  await page.locator('[data-testid="password"]').fill('••••••••');
  await page.locator('[data-testid="submit"]').click();
  await expect(page).toHaveURL('/dashboard');
});

How Does Playwright Generation Connect to the Full QA Workflow?

Playwright generation is the final step in QAMind's end-to-end automation pipeline. The pipeline runs in 4 stages: record a browser session, generate test cases with AI, approve the test suite, and convert to Playwright scripts.

Failed Playwright runs automatically surface in the bug tracker with test case links. Passed runs update the analytics dashboard with new coverage data. QA teams close the loop from recording to regression coverage without leaving QAMind.
