Severity Definitions

Browser Automation Workflow

Prerequisites:

• Playwright MCP server configured
• Node.js installed
• Application running locally or accessible URL

Playwright MCP Tools Available:

Process:

1. Navigate and Capture Initial State

"Navigate to http://localhost:3000/login"
"Take a screenshot of the current page"
"Get the accessibility snapshot"

2. Validate UI Elements

Using browser_snapshot to verify:
- Form fields are present and labeled
- Buttons have correct text
- Error messages are accessible
- Page structure matches requirements

3. Test User Interactions

"Click the 'Login' button"
"Fill the email field with 'test@example.com'"
"Verify the error message appears"
"Take a screenshot of the error state"

4. Capture Evidence for Bug Reports

"Take a screenshot of the current page"
"Get console messages for any errors"
"Document the accessibility tree for element structure"

What to Validate with Playwright MCP

Example Validation Queries

"Navigate to the checkout page and verify all form fields are present"
"Fill the login form and capture screenshot of the result"
"Click the submit button and check for console errors"
"Validate the navigation menu has all required links"
"Test the form validation by submitting empty fields"

Generating Automated Tests from Validation

After validating with Playwright MCP, generate automated .spec.ts tests:

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

test.describe('Login Page Validation', () => {
  test.beforeEach(async ({ page }) => {
    await page.goto('http://localhost:3000/login');
  });

  test('displays all required form elements', async ({ page }) => {
    await test.step('Verify form fields', async () => {
      await expect(page.getByRole('textbox', { name: 'Email' })).toBeVisible();
      await expect(page.getByRole('textbox', { name: 'Password' })).toBeVisible();
      await expect(page.getByRole('button', { name: 'Login' })).toBeEnabled();
    });
  });

  test('shows error for invalid credentials', async ({ page }) => {
    await test.step('Submit invalid credentials', async () => {
      await page.getByRole('textbox', { name: 'Email' }).fill('invalid@test.com');
      await page.getByRole('textbox', { name: 'Password' }).fill('wrongpass');
      await page.getByRole('button', { name: 'Login' }).click();
    });

    await test.step('Verify error message', async () => {
      await expect(page.getByRole('alert')).toContainText('Invalid credentials');
    });
  });
});

Suite Structure

Building a Regression Suite

Step 1: Identify Critical Paths

• What can users NOT live without?
• What generates revenue?
• What handles sensitive data?
• What's used most frequently?

Step 2: Prioritize Test Cases

Step 3: Execution Order

1. Smoke first - if fails, stop and fix build
2. P0 tests next - must pass before proceeding
3. P1 then P2 - track all failures
4. Exploratory - find unexpected issues

Pass/Fail Criteria

PASS:

• All P0 tests pass
• 90%+ P1 tests pass
• No critical bugs open

FAIL (Block Release):

• Any P0 test fails
• Critical bug discovered
• Security vulnerability
• Data loss scenario

CONDITIONAL:

• P1 failures with workarounds
• Known issues documented
• Fix plan in place
