//sample test case: 
  test("it can check whether this page url as specfied url or not ", async({page})=>{
 
    await page.goto("<https://localhost:3000/>")
    
    await expect(page).toHaveUrl("<https://localhost:3000/>")

    const pageUrl = PageTransitionEvent.url(); //get the current page url

    await page.close() //close 

  })

page fixture:

• the {page} argument tells Playwright Test to set up the page fixture and provide it to your test function.
• playwright test will set up the page fixture before running the test and tear it down after the test has finished.
• Test fixtures are isolated between tests.

  test("test case ", async({page})=>{
    await page.goto("<https://localhost:3000/>")    
    await expect(page).toHaveUrl("<https://localhost:3000/>")
  })
  
  test("test case ", async()=>{
    const browser = await chromium.launch()
    const context =await browser.newContext()
    const page= await context.newPage() 
    await page.goto("<https://localhost:3000/>")    
    await expect(page).toHaveUrl("<https://localhost:3000/>")
  })
