Data driven testing using java webdriver TestNg framework

In this post I implemented that how to perform data driven testing using java Webdriver  TestNg framework. As we know testNg provide @DataProvider annotation, using this I can pass a set of data into our Webdriver test method.  I have created a sample test script for Wikipedia where I use a set of country data, with Wikipedia search functionality and verify searched country.

package com.test;

import java.util.concurrent.TimeUnit;
import org.junit.Assert;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class DataDrivenTest {

  private WebDriver driver;
  private String baseUrl;
 
  @DataProvider(name = "myTest")
  public Object[][] createData1() {
          return new Object[][] {
            { "India"},
            { "Brazil"},
            { "Canada"},
            { "Sri Lanka"},
            { "England"},
            { "UK"},
            { "United States"},           
          };
  }
 
  @BeforeMethod
  public void setUp() throws Exception {
    driver = new FirefoxDriver();
    baseUrl = "http://www.wikipedia.org/";
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  }

  @Test(dataProvider = "myTest")
  public void testSearchCountry(String country) throws Exception {
    driver.get(baseUrl + "/wiki/Main_Page");
    driver.findElement(By.id("searchInput")).clear();
    driver.findElement(By.id("searchInput")).sendKeys(country);
    driver.findElement(By.id("searchButton")).click();
    String str = driver.findElement(By.cssSelector("span")).getText();
    Assert.assertTrue(country.equals(str.trim()));
  }

  @AfterMethod
  public void tearDown() throws Exception {
    driver.quit();   
  } 
}

Above test script executed seven times for each set of data used in @DataProvider annotation. Any failed test does not impact other set of execution.

After execution of above test script TestNg report should be generated as below:

Below are the execution log of above test:

PASSED: testSearchCountry("India")

PASSED: testSearchCountry("Brazil")

PASSED: testSearchCountry("Canada")

PASSED: testSearchCountry("Sri Lanka")

PASSED: testSearchCountry("England")

PASSED: testSearchCountry("United States")

FAILED: testSearchCountry("UK")

Above test failed for the value “UK” as searched result is “United Kingdom” not “UK”

Hope above test will help you for data driven testing. Comment here if you have any query.
