I have radio buttons that when either radio button is selected, it gets a checked attribute.

This is how the HTML looks:

My implementation of getting the descendant that has a checked attribute:

public TestObject getCheckedTestObjectFromParent(String parentID)
 WebDriver driver = DriverFactory.getWebDriver()
 WebElement parentWebElement = driver.findElement(By.id(parentID))

 List<WebElement> children = parentWebElement.findElements(By.xpath(".//*"))
 println(children.size())
 for(int i = 0; i < children.size(); i++)
 TestObject childTestObject = getTestObjectFromWebElement(children[i])
 if(WebUI.verifyElementHasAttribute(childTestObject, 'checked', 10, FailureHandling.OPTIONAL))
 return childTestObject
 
 

This is the helper method that I use for converting a WebElement to a TestObject :

public TestObject getTestObjectFromWebElement(WebElement element) 
 TestObject object = new TestObject()
 object.addProperty("xpath", ConditionType.CONTAINS, getXPathFromElement(element))
 return object
 

Helper for getting xpath from WebElement :

protected String getXPathFromElement(WebElement element) 
 String elementDescription = element.toString();
 return elementDescription.substring(elementDescription.lastIndexOf("-> xpath: ") + 10, elementDescription.lastIndexOf("]"));
 

Am I missing something here or is there something wrong with the WebElement -> TestObject conversion? Also is this possible using only TestObject or only WebElement? If I could get child TestObjects containing certain attributes from a parent TestObject then I wouldn't need to make a mess using WebElements.

Edit

Another image of the HTML, this time with the first radio button checked. As you can see the second radio button no longer has the 'checked' attribute.

Try this Xpath

"//input[@id='config-src-laserunits-wavnmradio' and @checked='checked']"

Example:

List<WebElement> children = driver.findElements(By.xpath("//input[@id='config-src-laserunits-wavnmradio' and @checked='checked']"))

It should return size 1

EDIT

 List<WebElement> children = driver.findElements(By.xpath("//input[@id='config-src-laserunits-wavnmradio']"));
 for (int i=0;i<children.size();i++)
 
 if(children.get(i).getAttribute("checked")!=null)
 
 System.out.println("radio button is checked");
 
 

Ok, If I undestand your query correctly - you want to know the which radio button is selected (THz or nm) based on checked attribute status.

Here is the xpath that will return the radio button that's selected.

selectedRadio = driver.findElement(By.xpath("//div[@id='config-src-laserunits-freqthz"]//input[@checked='checked']/following-sibling::label")).gettext();

This will work when any radio button selected in the above html.

To retrieve the WebElement that is currently checked you can use either of the following Locator Strategies:

• 
  

  cssSelector:

  
  
  

  WebElement elem = new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("div.a-toggle.a-toggle--anycase#config-src-laserunits div[id^='config-src-laserunits-']>input.a-toggle__radio[checked]")));
  

  
  


• 
  

  xpath:

  
  
  

  WebElement elem = new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@class='a-toggle a-toggle--anycase' and @id='config-src-laserunits']//div[starts-with(@id, 'config-src-laserunits-')]/input[@class='a-toggle__radio' and @checked]")));
  

  
  

I was able to fix this by changing (".//*") to (".//*[@checked='checked']")

 parentWebElement.findElement(By.xpath(".//*[@checked='checked']")

will find the element that has the attribute checked = 'checked'

Notice that a list is no longer needed as there can only be 1 checked radio button at a time.

Implementation

public TestObject getCheckedTestObjectFromParent(String parentID)
 WebDriver driver = DriverFactory.getWebDriver()
 WebElement parentWebElement = driver.findElement(By.id(parentID))

 //there is only 1 checked child at a time, so there is no need for a list
 WebElement checkedChild = parentWebElement.findElement(By.xpath(".//*[@checked='checked']"))

 //convert the WebElement to a TestObject and return
 return getTestObjectFromWebElement(checkedChild)
