[java] How do you tell if a checkbox is selected in Selenium for Java?

I am using Selenium in Java to test the checking of a checkbox in a webapp. Here's the code:

private boolean isChecked;
private WebElement e;

I declare e and assign it to the area where the checkbox is.

isChecked = e.findElement(By.tagName("input")).getAttribute("checked").equals("true");

What is weird is that getAttribute("checked") returns null and therefore a NullPointerException

In the HTML for the checkbox, there is no checked attribute displayed. However, isn't it the case that all input elements have a checked = "true" so this code should work?

For the event where there are multiple check-boxes from which you'd like to select/deselect only a few, the following work with the Chrome Driver (somehow failed for IE Driver):

NOTE: My check-boxes didn't have an ID associated with them, which would be the best way to identify them according to the Documentation. Note the ! sign at the beginning of the statement.

if(!driver.findElement(By.xpath("//input[@type='checkbox' and @name='<name>']")).isSelected()) 
{
  driver.findElement(By.xpath("//input[@type='checkbox' and @name= '<name>']")).click();
}

I would do it with cssSelector:

// for all checked checkboxes
driver.findElements(By.cssSelector("input:checked[type='checkbox']"));
// for all notchecked checkboxes
driver.findElements(By.cssSelector("input:not(:checked)[type='checkbox']"));

Maybe that also helps ;-)

1. Declare a variable.
2. Store the checked property for the radio button.
3. Have a if condition.

Lets assume

private string isChecked; 
private webElement e; 
isChecked =e.findElement(By.tagName("input")).getAttribute("checked");
if(isChecked=="true")
{

}
else 
{

}

Hope this answer will be help for you. Let me know, if have any clarification in CSharp Selenium web driver.

The mechanism of selenium framework:

Here selenium make request to the its server and fetch first subelement with tagname input

WebElement e = e.findElement(By.tagName("input"));

Than you try to receive attribute on that element

object attribute = e.getAttribute("checked")

So either use

findElement(By.attribute("checked")

or use

findElement(By.xpath("\\input[@checked='true']")

P.S. I'm not familiar with java's equivalent of selenium api so some method may be named slightly different.

public boolean getcheckboxvalue(String element)
    {   
        WebElement webElement=driver.findElement(By.xpath(element));
        return webElement.isSelected();
    }

 if(checkBox.getAttribute("checked") != null) // if Checked 
    checkBox.click();                         //to Uncheck it 

You can also add an and statement to be sure if checked is true.

if ( !driver.findElement(By.id("idOfTheElement")).isSelected() )
{
     driver.findElement(By.id("idOfTheElement")).click();
}
