Handle radio button & Check Boxes in Selenium

The main difference between Radio button and Checkbox is that, using radio button we will be able to select only one option from the options available. whereas using checkbox, we can select multiple options.

Selenium WebDriver supports Radio Button and Radio Group controls using the WebElement class. We can select and deselect the radio buttons using the click() method of the WebElement class and check whether a radio button is selected or deselected using the isSelected() method.

Before performing the click on the Radio buttons or check boxes we will have to verify follwing scenarios :-

• If Radio button or Checkbox is displayed on the webpage
• If Radio button or Checkbox is enabled on the webpage
• Check the default selection of the Radio button or Checkbox

We use predefined methods present in selenium to handle check Box and Radio  button :-

• isDisplayed()
• isEnabled()
• isSelected()

1. isDisplayed() this method returns a Boolean value, if it returns true then said webelement (radio) is present on the webpage or it returns False.

2. Using  isEnabled() this method  returns a Boolean value, if it returns true then said webelement (radio) button is enabled on the webpage or it returns False.

3. Using isSelected() method you can check that the element is selected or not.

@Test
public void testRadioButton()
{
//Get the Radiobutton as WebElement using it's value attribute

WebElement petrol = driver.findElement(By.xpath("//input[@value='Petrol']"));
 

//Check if its already selected? otherwise select the Radiobutton
//by calling click() method

if (!petrol.isSelected())
petrol.click();
//Verify Radiobutton is selected
assertTrue(petrol.isSelected());
//We can also get all the Radiobuttons from a Radio Group in a list
//using findElements() method along with Radio Group identifier
 

List<WebElement> fuel_type = driver.findElements(By.name("fuel_type"));
for (WebElement type : fuel_type)
{
//Search for Diesel Radiobutton in the Radio Group and select
//it
if(type.getAttribute("value").equals("Diesel"))
{
if(!type.isSelected())
type.click();
assertTrue(type.isSelected());
break;
}
}
}
