How to wait until dropdown selected text matches other text using selenium?

问题

HTML:

<select name="ddlFruit" id="ddlFruit" class="Searchddl">
    <option value="">Select</option>
    <option value="447">Grapes</option>
    <option value="448">Mango</option>
    <option selected="selected" value="449">Apple</option>
</select>

Suppose "Apple" is in first selected mode, due to some other actions on site, this drop-down changes to other options automatically. I want webdriver to wait until "Mango" text is in selected mode.

Tried code:

public static SelectElement FindSelectElementWhenPopulated(IWebDriver driver, By by, int delayInSeconds, string optionText)
    {
        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(delayInSeconds));
        return wait.Until<SelectElement>(drv => 
        {
            SelectElement element = new SelectElement(drv.FindElement(by));
            if (element.SelectedOption.ToString().Contains(optionText))
            {
                return element;
            }

            return null;
        }
        );
    }

Myclass.FindSelectElementWhenPopulated(driver, By.CssSelector("#ddlFruit"), 20, "Mango");

I am using C#.

You don't want to convert the SelectedOption to a string. Test the Text property instead:

if (element.SelectedOption.Text.Contains(optionText))

With a few changes, you can make this a handy extension method on WebDriverWait:

public static SelectElement UntilOptionIsSelected(this WebDriverWait wait, By by, string optionText)
{
    return wait.Until<SelectElement>(driver => 
    {
        var element = new SelectElement(driver.FindElement(by));

        if (element.SelectedOption.Text.Contains(optionText))
        {
            return element;
        }

        return null;
    });
}

And to use it:

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(20));
var dropdown = wait.UntilOptionIsSelected(By.CssSelector("#ddlFruit"), "Mango");

You need to use the Select class in Selenium:

Select dropdowns=new Select(driver.findelement(By.id("ddlFruit")));
dropdowns.selectByVisibleText("Mango");
