Reading Font Properties In Selenium WebDriver Using .getCssValue() Method

Sometimes you need to read font properties like font size, font color, font family, font background color etc.. during WebDriver test case execution. Selenium WebDriver Is very wast API and It has many built In methods to perform very small small operations on web page.Reading font property manually Is very simple task using firebug as shown In bellow given Image

If you wants to read above shown font property In selenium webdriver then you can do It using .getCssValue() Method. You can provide property name (Example : font-family, font-size, font-weight, etc.) with .getCssValue() method to read Its value.

Bellow given example will read values of font-size, color, font-family and text-align properties of "Example Login Page" text.

package Testing_Pack;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.testng.annotations.BeforeTest;

import org.testng.annotations.Test;

public class fontTest { 

WebDriver driver = null;

    @BeforeTest

    public void setup() throws Exception {  

  driver = new FirefoxDriver();

         driver.manage().window().maximize();

         driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

         driver.get("http://any login page");

    }

 @Test

 public void readFontProperty(){

  //Locate text string element to read It's font properties.

  WebElement text = driver.findElement(By.xpath("//h1[contains(.,'Example Login Page')]"));

  

  //Read font-size property and print It In console.

  String fontSize = text.getCssValue("font-size");

  System.out.println("Font Size -> "+fontSize);

  

  //Read color property and print It In console.

  String fontColor = text.getCssValue("color");

  System.out.println("Font Color -> "+fontColor);

  

  //Read font-family property and print It In console.

  String fontFamily = text.getCssValue("font-family");

  System.out.println("Font Family -> "+fontFamily);

  

  //Read text-align property and print It In console.

  String fonttxtAlign = text.getCssValue("text-align");

  System.out.println("Font Text Alignment -> "+fonttxtAlign);

 }

}

Output of above example Is as bellow.

Font Size -> 26.4px

Font Color -> rgba(102, 102, 102, 1)

Font Family -> "Trebuchet MS",Trebuchet,Verdana,sans-serif

Font Text Alignment -> left

Open a link in a New tab

We use actions objects to open any hyperlink in a new tab. e.g.

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Actions;
import org.testng.annotations.Test;
import java.util.concurrent.TimeUnit;

public class NewTab {
    public static void main(String[] args) {
       WebDriver driver = new FirefoxDriver();
        driver.get("http://www.flipcart.com/");
        driver.manage().window().maximize();
        Actions act = new Actions(driver);
        WebElement link = driver.findElement(By.linkText("Flipkart First"));
        act.moveToElement(link).contextClick().sendKeys("F").perform();
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
         driver.close();
   
    }
}

Final ,finally and finalize()?

Final:

• Any variable declare along with final modifier then those variables treated as final variable.
•  if we declare final variables along with static will became constants.
• public final String name = "foo"; //never change this value
• If you declare method as final that method also known as final methods.Final methods are not overridden.means we can't overridden that method in anyway.
• public final void add(){
   }
   public class A{
   void add(){
   //Can't override
   }
  
   }
• If you declare class is final that class is also known as final classes.Final classes are not extended.means we can't extens that calss in anyway.
• public final class indhu{
   }
   public class classNotAllowed extends indhu {...} //not allowed

Finally:

• Finally blocks are followed by try or catch.finally blocks are complasary executable blocks.But finally is useful for more than just exception handling.
•  it allows the programmer to avoid having cleanup code accidentally bypassed by a return,
   continue, or break,Closing streams, network connection, database connection. Putting cleanup  code in a finally block is always a good practice even when no exceptions are anticipated
•  where finally doesn't execute e.g. returning value from finally block, calling System.exit from try block etc
• finally block always execute, except in case of JVM dies i.e. calling System.exit() . 
  
   lock.lock();
  try {
    //do stuff
  } catch (SomeException se) {
    //handle se
  } finally {
    lock.unlock(); //always executed, even if Exception or Error or se
    //here close the database connection and any return statements like that we have to write
  }

Finalize():

• finalize() is a method which is present in Java.lang.Object class.
•  Before an object is garbage collected, the garbage collector calls this finalize() of object.Any unreferncebefore destorying if that object having any connections with databse or anything..It will remove  the connections and it will call finalize() of object.It will destroy the object.
• If you want to Explicitly call this garbage collector you can use System.gc() or Runtime.gc() objects are there from a long time the garbage collector will destroy that objects.
• public void finalize() {
    //free resources (e.g. unallocate memory)
    super.finalize();
  }
