WebElement interface methods examples in selenium - part 2 | Understanding of methods isDisplayed() Vs isEnabled() Vs isSelected()

• To verify presence of a web-element with in the web page. 
• This method returns either true or false boolean values. 
• If the element is present it returns "true" otherwise it returns "false". 
• This method avoids the problem of having to parse an element's "style" attribute.
• This method can be applicable for almost all of the elements on web-page.

<bxpath="1">This is sample text.</b>

//isDisplayed() | Text on web page | Example : This is sample text.
WebElement ThisIsSimpleText = driver.findElement(By.xpath("//b[contains(text(),'This is sample text.')]"));
boolean b1 = ThisIsSimpleText.isDisplayed();
System.out.println("Verify dispaly status of the text \"This is sample Text\"="+b1);

• To verify if an element is enabled or disabled on web-page. 
• Returns "ture" if element is enabled and returns "false" if an element is disabled. 
• Examples: Mostly used with button elements, locked/disabled text input elements. 

• Returns whether an element say check box or radio button is selected or not. 
• If selected returns "true", if not selected returns "false". 
• Examples: Check boxes, drop downs , radio buttons

<inputid="male"type="radio"name="gender"value="male"xpath="1">

//isSelected()  | Example :  male radio button
WebElement maleRaditoButton = driver.findElement(By.xpath("//input[@id='male']"));
boolean b2 = maleRaditoButton.isSelected(); //false
System.out.println("Verify male radio button selected or not before click = "+b2);
//select the male radio button and verify isSelected()
maleRaditoButton.click();
boolean b3 = maleRaditoButton.isSelected(); //true
System.out.println("Verify male radio button selected or not after click = "+b3);
