Selenium: How to wait for options in a select to b

Question

I am using Selenium for the first time and am overwhelmed by the options. I am using the IDE in Firefox.

When my page loads, it subsequently fetches values via an JSONP request, with which it populates options in a select.

How do I get Selenium to wait for a certain option in the select to be present before proceeding?

Answer 1

I think you should be use

waitForElementPresent command. If possible let's me see your selenium IDE code.

Answer 2

Using java 8 Awaitility

Awaitility.await()
.atMost(5, TimeUnit.SECONDS)
.until(() -> select.getOptions().size() > 0);

Answer 3

Its work for me:

  WebElement element = driver.findElement(By.xpath("//select[@name='NamE']/option[1]"));
  return element.getAttribute("text");

Answer 4

I used waitForElementPresent with a css target.

Example: To wait for

<select id="myselect"></select>

to be populated with

<option value="123">One-two-three</option>

use

• Command: waitForElementPresent
• Target: css=#myselect option[value=123]
• Value: (leave it empty)

Answer 5

I made the following function in C# that returns the select when is populated.

You have to pass a By to find the element and you a specific time to wait for it to be filled:

public static SelectElement FindSelectElementWhenPopulated(this IWebDriver driver, By by, int delayInSeconds)
    {
        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(delayInSeconds));
        return wait.Until<SelectElement>(drv => 
        {
            SelectElement element = new SelectElement(drv.FindElement(by));
            if (element.Options.Count >= 2)
            {
                return element;
            }

            return null;
        }
        );
    }

In my case I validate tha the select has more than 2 options, you can change the code so that it validates the quantity that fits your needs.

Answer 6

We had similar problem where the options within drop down was fetched from a third party service, which sometimes was a slower operation.

Select select = new Select(driver.findElement(cssSelector("cssSelectorOfSelectBox")));    
waitUnitlSelectOptionsPopulated(select)

here is the definition for waitUnitlSelectOptionsPopulated

private void waitUntilSelectOptionsPopulated(final Select select) {
            new FluentWait<WebDriver>(driver)
                    .withTimeout(60, TimeUnit.SECONDS)
                    .pollingEvery(10, TimeUnit.MILLISECONDS)
                    .until(new Predicate<WebDriver>() {
                        public boolean apply(WebDriver d) {
                            return (select.getOptions().size() > 1);
                        }
                    });
        }

Note: A check of select.getOptions().size() >1 was needed in our case as we had one static option always displayed.
