how to differentiate the answers format(Checkbox or Textarea etc.) while working with for loop - selenium

Question

I have a scenario where 15 questions are there and i do have to select the answer either by selecting radiobutton or checkbox or Yes/No button or have to enter some text in textarea.
My following code successfully selecting the answer randomly whether its a radio/checkbox or Yes/No button and displays the selected option as an answer along with question on console.
But how do i check if its textarea and need to enter something with 'sendKeys? And how do i select more than one checkboxes? And how do i display the answer Yes or No onconsole?
public void AssessmentTest() throws Exception
{
List<WebElement>totalQSN = driver.findElements(By.xpath("//div[#id='assessmentQuestionAnswersContainer']/div"));
List<WebElement> mainQuestions = driver.findElements(By.xpath("//div[#id='assessmentQuestionAnswersContainer']/div/div[2]/div"));
System.out.println("The Questions are::");
for(int i=0; i<totalQSN.size()-5; i++)
{
System.out.println("QUESTION:- " + mainQuestions.get(i).getText() + "["+ i +"]" );
Random rnd = new Random();
List<WebElement> subOptions = totalQSN.get(i).findElements(By.tagName("input"));
WebElement sValue = subOptions.get(rnd.nextInt(subOptions.size()));
sValue.click();
List<WebElement> subQsnList = driver.findElements(By.xpath("//div[#id='assessmentQuestionAnswersContainer']/div/div[3]/div/span/span"));
System.out.println(subOptions.size());
for(int j=0; j<subOptions.size(); j++)
{
if(subOptions.get(j).isSelected())
{
String selectedAnswer= subQsnList.get(j).getText();
System.out.println("ANSWER: - " + selectedAnswer);
System.out.println("\n");
}
}
} }
HTML Code is as under for each type of question.
<div id="individualQuestionAnswerContainer147" class="individual-question-answer-container" style="display: block;" xpath="1">
<div class="individual-questions-count-container"></div>
<div id="questionContainer147" style="clear: both; float: left;"></div> //Contains Question
<div id="questionAnswerContainer147" class="answers-container"></div> //Contains Answers
</div>
If the question having checkboxes, the code is
<div id="individualQuestionAnswerContainer148" class="individual-question-answer-container" style="" xpath="2"> Contains 4 checkbox(divs)
<div class="individual-questions-count-container"></div>
<div id="questionContainer148" style="clear: both; float: left;"></div>
<div id="questionAnswerContainer148" class="answers-container" style="">
<div class="answer-text">
<span class="answer-text-inner btn-assessment-answer">
<input type="checkbox" name="Checkbox148" id="Checkbox449" class="radio-assessment-answer">
<span style="display: table;">
Good
</span>
</span>
</div>
<div class="answer-text">
<span class="answer-text-inner btn-assessment-answer">
<input type="checkbox" name="Checkbox148" id="Checkbox450" class="radio-assessment-answer">
<span style="display: table;">
Mold
</span>
</span>
</div>
<div class="answer-text"></div>
<div class="answer-text"></div>
</div>
</div>
If question having 2 buttons(Yes/No), the code is
<div id="individualQuestionAnswerContainer155" class="individual-question-answer-container" style="" xpath="7"> Contains 2 options Yes or No
<div class="individual-questions-count-container"></div>
<div id="questionContainer155" style="clear: both; float: left;"></div>
<div id="questionAnswerContainer155" class="answers-container" style="">
<input type="button" value="Yes" id="Button477" class="btnClass_155 btn-assessment-answer" style="">
<input type="button" value="No" id="Button478" class="btnClass_155 buttonClicked btn-assessment-answer">
</div>
</div>
If question having textarea, the code is
<div id="questionAnswerContainer38" class="answers-container" xpath="1">
<textarea maxlength="50000" rows="2" cols="100" id="FreeTextarea38"></textarea>
</div>

Answer 1

Try using this structure..Hope this helps.
public void AssessmentTest() throws Exception
{
List<WebElement>totalQSN = driver.findElements(By.xpath("//div[#id='assessmentQuestionAnswersContainer']/div"));//Assuming this xpath is correct
List<WebElement> mainQuestions = driver.findElements(By.xpath("//div[#id='assessmentQuestionAnswersContainer']/div/div[2]/div")); //Assuming this xpath is correct
System.out.println("The Questions are::");
for(int i=0; i<totalQSN.size()-5; i++)
{
System.out.println("QUESTION:- " + mainQuestions.get(i).getText() + "["+ i +"]" );
Random rnd = new Random();
String webeleTag=totalQSN.get(i).getTagName();
if(webeleTag.equals("input"))){
String webeleType=totalQSN.get(i).getAttribute("type");
switch(webeleType){
case:"checkbox":
//your code to select check box
case:"button":
//Only click event on answer
default:
}
}
else if(webeleTag.equals("textarea")){
//your code
}
else{
//Not text area,checkbox or radio something else
}
}
}

Answer 2

To detect if it is a text area, from the top of my head you can go
for .getTagName() this will return the tag of the element.
To get all the checkboxes you can use driver.findElements(By.id("questionAnswerContainer148")).toArray(new WebElement[0]) , this will return an array with the checkboxes and you can use some logic to click in the items you want from the list.
For the yes/no, I think that the driver.findElement(by).getAttribute("value") will return the content of the attribute.
Hope this helps you.
