Selenium C# 使用 IWebElement 的预期条件

Question

I want to make a class WaitForElement with methods likes But ExpectedConditions.ElementIsVisible expect (By) not (IWebElement)

class WaitForElement
    {
(...)
public void waitUntilElementIsVisible(IWebElement element)
       {
           WebDriverWait webDriverWait = GetWebDriverWait();
           webDriverWait.Until ( ExpectedConditions.ElementIsVisible(element) );
       }

In my PageObject classes I use

 public IWebElement orderTab => Driver.FindElement(By.XPath("//a[contains(@href,'order')]"));

so I wanted to use it like that:

WaitForElement.waitUntilElementIsVisible(orderTab)

Is there any option to make it works? I can't use

public By orderTab => By.XPath("//a[contains(@href,'order')]");

Answer 1

The code to wait for an element to be visible is actually very simple.

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30));

wait.Until(d => d.FindElement(By.XPath("//a[contains(@href,'order')]")).Displayed);

I like to create extension methods for the WebDriverWait class for things like this:

namespace OpenQa.Selenium
{
    public static class WebDriverWaitExtensions
    {
        public static bool UntilElementIsDisplayed(this WebDriverWait wait, By locator)
        {
            return wait.Until(driver => driver.FindElement(locator).Displayed);
        }
    }
}

And to use it, all you need is a WebDriverWait object and using OpenQa.Selenium; at the top of the C# file:

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30));

wait.UntilElementIsVisible(By.XPath("//a[contains(@href,'order')]"));
