Playwright的wait funtion测试的实现

/**

/**

 * @param {*} page 
 * @param {*} locator 
 * @param {*} option 
 * @param {*} timeout 
 */
const selectDropDown = async (page, locator, option, timeout = 500) => {
  // 1. Click the dropdown trigger
  await page.locator(locator).click();
  // 2. Wait for the option text to be visible anywhere on the page
  // This is robust for PrimeFaces where options are often divs/li with text content
  const optionLocator = page.getByText(option, { exact: true }).first();
  // Wait up to 5 seconds for the option to appear
  await expect(optionLocator).toBeVisible({ timeout: 5000 });
  // 3. Click the option
  await optionLocator.click();
