Executing Selenium tests using TestNG

To write Selenium tests, we will need to add below dependencies in TestNG project.

    <dependency>
      <groupId>org.testng</groupId>
      <artifactId>testng</artifactId>
      <version>6.9.10</version>
      <scope>test</scope>
    </dependency>

    <dependency>
      <groupId>org.seleniumhq.selenium</groupId>
      <artifactId>selenium-java</artifactId>
      <version>2.53.0</version>
      <scope>test</scope>
    </dependency>

Then we can create a Base Test class that has the definitions for @BeforeMethod and @AfterMethod. Note that we have instantiated the webdriver instance in @BeforeMethod and We have closed the webdriver in @AfterMethod. We have also written a code to take the screenshot in case of failure.

package org.softpost;

import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.ITestResult;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;

import java.io.File;

/**

public class BaseTest {
    WebDriver driver;

    @BeforeMethod
    public void setup(){
      driver = new FirefoxDriver();
    }

    @AfterMethod
    public void cleanup(ITestResult result){
        if (result.getStatus()==ITestResult.FAILURE){
            System.out.println("Test Failed");
            //Here we can take screen shot
            File f = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
            try {
                FileUtils.copyFile(f,
                        new File("C:\\Users\\Sagar\\IdeaProjects\\TestNG-Project\\abc.png"));
            }catch (Exception ex){
                System.out.println("exception " +ex.getMessage());
            }
        }
        driver.close();
        driver.quit();
    }
}

Below is the actual test Class. In this test, we are verifying the title of website – www.softpost.org

package org.softpost;

import org.testng.Assert;
import org.testng.annotations.Test;

public class SeleniumTests extends BaseTest {

    @Test
    public void test1(){
       driver.get("https://www.softpost.org");
        Assert.assertTrue(driver.getTitle().contains("My Tutorials"));
    }
}
