Playwright的wait funtion测试的实现

/**
 * selects an option from a primefaces/jsf dropdown menu.
 * @param {*} page 
 * @param {*} locator 
 * @param {*} option 
 * @param {*} timeout 
 */
const selectdropdown = async (page, locator, option, timeout = 500) => {
  await page.locator(locator).click();
  await page.waitfortimeout(timeout);
  await page.getbyrole('option', { name: option }).click();
  await page.waitfortimeout(timeout);
}

/**
 * selects an option from a primefaces/jsf dropdown menu.
 * @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();
