playwright testing parallel-testing JavaScript

I've been struggling with this for a few days now and could really use some help. I'm working with an scenario when trying to run Playwright tests in parallel, where tests that depend on specific session states are failing. I have a test suite that logs in a user, and then several tests check the user’s profile and dashboard. However, when running these tests concurrently, they seem to interfere with each other, leading to inconsistent states. Here’s a simplified version of my test code: ```javascript const { test, expect } = require('@playwright/test'); const BASE_URL = 'https://example.com'; let userSession; test.beforeAll(async ({ browser }) => { const context = await browser.newContext(); const page = await context.newPage(); await page.goto(`${BASE_URL}/login`); await page.fill('#username', 'testuser'); await page.fill('#password', 'password123'); await page.click('#login-button'); userSession = context; }); test('Check User Profile', async () => { const page = await userSession.newPage(); await page.goto(`${BASE_URL}/profile`); const profileName = await page.innerText('.profile-name'); expect(profileName).toBe('Test User'); }); test('Check User Dashboard', async () => { const page = await userSession.newPage(); await page.goto(`${BASE_URL}/dashboard`); const dashboardTitle = await page.innerText('.dashboard-title'); expect(dashboardTitle).toBe('Welcome to Your Dashboard'); }); ``` When I run these tests with `npx playwright test --workers=4`, I often get errors like `behavior: expected 'Welcome to Your Dashboard' but received 'Access Denied'`. It seems like the session from the previous test isn't being isolated, and the second test fails due to session state bleed. I’ve tried creating separate contexts for each test, but that requires a lot of duplicated login logic and increases test runtime. Is there a more efficient way to handle session management in Playwright when running tests in parallel without duplicating code? Any advice or best practices would be greatly appreciated! What am I doing wrong?
