What is Properties?
It is mainly used to store configuration parameters of an application. Each parameter is stored as a pair of strings i.e. both key and value are of type string.

How to use Properties Files with Selenium?
- It can be used to store all the configuration parameters like environment details, user credentials, database details, etc.… instead of hard coding it in the scripts
- It can be used as an object repository where we can store all the elements and their identifiers
Example:
public class FirstTest {
@Test
public void OpenBrowser() {
String driverPath = PropertyFileUtils.loadFrameworkProperties().getProperty("chrome.driver.path");
String url = PropertyFileUtils.loadApplicationProperties().getProperty("application.url");
WebDriver driver;
System.setProperty("webdriver.chrome.driver", driverPath);
driver = new ChromeDriver();
driver.get(url);
System.out.println(driver.getTitle());
Assert.assertTrue("Page title is not correct",driver.getTitle().equals("Google"));
driver.quit();
}
}
public class PropertyFileUtils {
public static Properties loadProperties(String path){
Properties properties = new Properties();
FileInputStream file = null;
try {
file = new FileInputStream(path);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
try {
properties.load(file);
} catch (IOException e) {
e.printStackTrace();
}
return properties;
}
public static Properties loadApplicationProperties(){

public static Properties loadFrameworkProperties(){
