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?
I think you should be use
waitForElementPresent
command. If possible let's me see your selenium IDE code.
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)
You can use "WaitForSelectOption" command where your value can be direct label like label=1-saving Account target will have the object id
I found handy something like:
wait.until(
ExpectedConditions
.presenceOfNestedElementsLocatedBy(By.id(<selectioNId>), By.tagName("option"))
)
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.
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.
Using java 8 Awaitility
Awaitility.await()
.atMost(5, TimeUnit.SECONDS)
.until(() -> select.getOptions().size() > 0);
Its work for me:
WebElement element = driver.findElement(By.xpath("//select[@name='NamE']/option[1]"));
return element.getAttribute("text");
