Webdriver how to check the availability of a site’s url and the host ?

As a software test automation engineer, based on the availability of my testing site , I want to execute my suite . Problem I am facing it , before run my plan I want to check the site is available , or else my scripts will be started to execute , even though my site is down .

Solution- Before running your plan , in before suite method using java.net you can check your host and site are available , usually in @BeforeClass or @BeforeSuite so if the site is available only your suite get executed .

Sample code is given below .

package com.webdriver.blogs;
import java.awt.datatransfer.UnsupportedFlavorException;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.InetAddress;
import java.net.URL;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.testng.Assert;
import org.testng.annotations.AfterSuite;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;
public class ExecutionbasedOnTReachabilityOfSite {
WebDriver driver;
@BeforeClass()
public void setUp() throws IOException {
System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir") + "\\Jar_files\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
// To start Chrome in Maximized browser window
options.addArguments("start-maximized");
// To remove Chrome is being controlled by automated test software
options.addArguments("disable-infobars");
driver = new ChromeDriver(options);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
driver.manage().window().maximize();
//you can use String Host
InetAddress addressSite = InetAddress.getByName("google.com");
System.out.println("================================="+addressSite.getHostAddress());
String host=addressSite.getHostAddress();
// Or using DNS of the  host
InetAddress address = InetAddress.getByName("facetwirrer.co");
boolean reachable = address.isReachable(10000);//timeout in milliseconds
System.out.println("Is host reachable? " + reachable);
Assert.assertEquals(true, reachable, "The host is unavaiable");
URL url = new URL("https://www.google.com/");
HttpURLConnection httpURLConnect=(HttpURLConnection)url.openConnection();
httpURLConnect.setConnectTimeout(3000);
httpURLConnect.connect();
Assert.assertEquals(200, httpURLConnect.getResponseCode(), "The site is unavaiable");
System.out.println("Is site reachable? yes " + httpURLConnect.getResponseCode());
}
@Test(priority = 1)
public void navigateToWebSite() throws UnsupportedFlavorException, IOException {
// Navigate to the URL
driver.get("https://www.google.com/");
System.out.println("The title of the Site is " + driver.getCurrentUrl());
}
@AfterSuite()
public void shutDown() {
driver.close();
driver.quit();
try {
Runtime.getRuntime().exec("taskkill /F /IM chromedriver.exe");
} catch (IOException e1) {
e1.printStackTrace();
}
System.out.println("***************End of testing shutdown happend **************************");
}
}
