How to read data from Properties file in Selenium Webdriver using Java.

'.properties' files have configuration data, database config or project settings etc to maintain project in Java. Each parameter in properties file are stored as a pair of strings, in key and value format and key is case sensitive, where each key is on one line. You can easily read properties from some file using object of type Properties.

In Selenium .properties files are mainly used to store GUI locators / elements, and also Global fields like database configuration details.

The sample properties file that was used for the java program

Here is a example program which demonstrate to read the data from .properties file using Java.

 import java.io.File;  
 import java.io.FileInputStream;  
 import java.io.FileNotFoundException;  
 import java.io.IOException;  
 import java.util.Properties;  
 import org.openqa.selenium.By;  
 import org.openqa.selenium.NoSuchElementException;  
 import org.openqa.selenium.WebDriver;  
 import org.openqa.selenium.firefox.FirefoxDriver;  
 public class Readdatafrompro {  
 public static void main(String[] args) {  
 try {  
 // Create FileInputStream Object  
 FileInputStream fileInput = new FileInputStream(new File("data.properties"));  
 // Create Properties object  
 Properties prop = new Properties();  
 //load properties file  
 prop.load(fileInput);  
 //// WebDriver reference but Firefox object  
 WebDriver driver = new FirefoxDriver();  
 //Maximize browser window    
 driver.manage().window().maximize();  

 //Visit to Facebook   
 driver.get(prop.getProperty("URL"));  
 //Read Username from Properties and send to facebook Username text field  
 driver.findElement(By.id("email")).sendKeys(prop.getProperty("Username"));  
 //Read Password from Properties and send to facebook password text field   
 driver.findElement(By.id("pass")).sendKeys(prop.getProperty("Password"));  
 driver.findElement(By.id("loginbutton")).click();  

 if (driver.getPageSource().contains("Please re-enter your password")) {  
   System.out.println("--- Pass ---");  
 } else {  
   System.out.println("!!!! Fail !!!");  
 }  

 //Print Properties Values  
 System.out.println("URL    =: " + prop.getProperty("URL"));  
 System.out.println("User name =: " + prop.getProperty("Username"));  
 System.out.println("Password =: " + prop.getProperty("Password"));  

 // Browser close    
 driver.close();
   
     } catch (FileNotFoundException e) {  
 e.printStackTrace();  
     } catch (IOException e) {  
 e.printStackTrace();  
     } catch (NoSuchElementException e) {  
 e.printStackTrace();  
     }  
   }  
 }
