How to verify an attribute is present in an element using Selenium WebDriver?

Question

I have many radio buttons on my screen. When a radio button is selected, it has an attribute of checked. When the radio button is not selected, the checked attribute is not

Answer 1

Look here:

getAttribute(java.lang.String name)

Returns: The attribute's current value or null if the value is not set.

Use whatever test framework you're using to assert that the value is null

Assert.IsNull(getSingleElement(XXX).getAttribute("checked"));

Answer 2

Checkboxes can tricky sometimes, because the attribute checked may not be followed by an attribute value.

If you're only concerned with the presence of the attribute, a simple check would look like this:

 boolean hasAttr_css = driver.findElementsByCssSelector("#input_id[checked]").isEmpty();

Answer 3

You can create a method to handle it properly. Note this following is in C#/Java mixed style, you need to tweak a bit to compile.

private boolean isAttribtuePresent(WebElement element, String attribute) {
    Boolean result = false;
    try {
        String value = element.getAttribute(attribute);
        if (value != null){
            result = true;
        }
    } catch (Exception e) {}

    return result;
}

How to use it:

WebElement input = driver.findElement(By.cssSelector("input[name*='response']"));
Boolean checked = isAttribtuePresent(input, "checked");
// do your assertion here

Answer 4

try { 
if (webdriver.findElement(By.identificationMethod(value)).getAttribute(value) != null) {
       passed = false;
    }
} catch (Exception e) {
    passed = true;
}

Was the sort of solution I used when I needed to check for element presence, however it must be noted that NullPointer errors were not caught by the NoSuchElement exception.

Answer 5

Unfortunately the accepted answer is not valid in the case reported. For some reason for Cr and FF non-existing attributes return empty string rather than null. Issue linked: https://github.com/SeleniumHQ/selenium/issues/2525

Answer 6

For asserting radio button is selected

Assert.assertTrue(element.isSelected());

For asserting radio button is not selected

Assert.assertFalse(element.isSelected());

For asserting an attribute is present in element

Assert.assertEquals(element.getAttribute(attributeName), expectedAttributeValue);
