How do you create a global configuration for Playwright .NET?
Using a selector that finds a list of locators in Playwright is exactly the same as calling .FindElements() in selenium, except that Playwright does not have a specifically named method like .FindLocators().
Playwright - a selector that matches multiple elements returns a list of locators, which you then iterate over:
var rows = page.GetByRole(AriaRole.Listitem);
var count = await rows.CountAsync();
for (int i = 0; i < count; ++i)
Console.WriteLine(await rows.Nth(i).TextContentAsync());
Selenium - FindElements returns a list of elements that you have to iterate over.
IList < IWebElement > elements = driver.FindElements(By.TagName("p"));
foreach(IWebElement e in elements) {
System.Console.WriteLine(e.Text);
}
