How to Configure Selenium WebDriver

Hola Testers,

Today I’m going to to tell how to configure Selenium WebDriver. Yes, this is the first lesson for Selenium WebDriver. I hope this will be useful for new users. In here, I’m going to use Java as my programming language. I’m going to divide this tutorial for below partitions.

  • Create a project and configure .jar files
  • Configure TestNG
  • Configure Firefox browser
  • Configure Chrome browser
  • Configure Internet Explore browser

Create a project and configure .jar files

To create a project we need programming IDE. Here I’m using eclipse.

  • Open Eclipse
  • Create a new Java Project

After create a java project we need to download selenium webdriver jars.

  • Go to seleniumhq download page
  • Download and unzip the WebDriver bindings

  • Create a folder called “libs” in java project (right click on the project > New > Folder)

Screen Shot 2017-04-11 at 5.37.45 PM

  • Paste all the .jar files from extracted folder of the downloaded zip file

Configure Firebox browser

  • Download geckoDriver from seleniumhq download page Third Party Drivers, Bindings and Plugins section and unzip it

Screen Shot 2017-04-11 at 9.19.58 PM

  • Create a folder called “driver” in project and add unzipped file. Don’t copy through eclipse.

Screen Shot 2017-04-11 at 9.40.04 PM.png

  • Create a class
  • Import Firefox browser driver
import org.openqa.selenium.firefox.FirefoxDriver
  • Initialize FirefoxDriver object
System.setProperty("webdriver.gecko.driver", "path of geckodrivergeckodriver"); 
FirefoxDriver fd=new FirefoxDriver();

Sample code

@Test

  public void firefoxTest() {

 System.setProperty("webdriver.gecko.driver", "/Users/deranthika/Documents/eclipse/workspace/TestSelenium/drivers/geckodriver");

FirefoxDriver fd=new FirefoxDriver();

fd.get("http://google.lk");

  }

If you are using windows OS, you need to put location as below

System.setProperty("webdriver.gecko.driver","path of geckodriver.exe");

Configure Chrome browser

  • Instead of gecko, you need to download chromeDriver from seleniumhq download page
  • Download the latest stable version for your OS and copy it to drivers folder
  • Import chromeDriver
import org.openqa.selenium.chrome.ChromeDriver;
  • Create new test method
  • Initailize chromeDriver object
System.setProperty("webdriver.chrome.driver", "/Users/deranthika/Documents/eclipse/workspace/TestSelenium/drivers/chromedriver");

ChromeDriver cd=new ChromeDriver();

sample code

@Test

  public void chromeTest() {

 System.setProperty("webdriver.chrome.driver", "/Users/deranthika/Documents/eclipse/workspace/TestSelenium/drivers/chromedriver");

ChromeDriver cd=new ChromeDriver();

cd.get("http://google.lk");

  }

Configure Internet Explorer browser

  • you need to download InternetExplorerDriver from seleniumhq download page
  • Download the latest stable version and copy it to drivers folder
  • Import InternetExplorerDriver
import org.openqa.selenium.ie.InternetExplorerDriver;
  • Create new test method
  • Initailize InternetExplorerDriver object
System.setProperty("webdriver.ie.driver", "C:\\Selenium\\IEDriverServer.exe");

InternetExplorerDriver id= new InternetExplorerDriver();

sample code

@Test

  public void chromeTest() {

System.setProperty("webdriver.ie.driver", "C:\\Selenium\\IEDriverServer.exe");

InternetExplorerDriver id= new InternetExplorerDriver();

id.get("http://google.lk");

  }

Run a TestNG project with Maven

Hola Testors!

Today I’m gonna show you how to run TestNG project with Maven. I’m taking my previous TestNG project for this one. You can download it from here.

I tried to run it in maven. Build got success. But you won’t see run anything.

There is a solution for this: surefire plugin 😀

You need to add testng dependency to pom.xml and add below plugin too.


<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.18.1</version>
            <configuration>
                <suiteXmlFiles>
                    <suiteXmlFile>crossbrowsing.xml</suiteXmlFile>
                </suiteXmlFiles>
            </configuration>
        </plugin>
    </plugins>
</build>

Here suiteXmlFile is out testng xml. You can pass many parameters with this plugin according to your scenarios. For more info about maven testng surefire plugin visit maven page.

See you soon!

Cross Browser Testing with TestNG

Hola Testors!

Cross browser testing become important when you are executing automation script on regression. Because your customer may request to work the particular web application on different browsers. So you need to automate the application to run in different browsers. As with our current script it will support only one browser at a time. So you have to change your browser parameter and have to run it again and again. That is why cross browser concept came to picture. By using TestNG we can easily do cross browser testing. Let’s do it!

There are two ways to do cross browser testing;

  1. Sequential order
  2. Parallel order

Sequential

First we look at how to do it on sequentially.

First Create a sample project (I’m creating sample maven project called crossbrowserTest )and apply all the dependancies.

Since this is TestNG, we have to include TestNG dependancy to our pom.xml.

<dependency>
     <groupId>org.testng</groupId>
     <artifactId>testng</artifactId>
     <version>6.9.6</version>
</dependency>

You can download TestNG repositories or JAR from maven repository by clicking here.

Then I’m creating a class to test google home page in different browsers. So, I’m creating a java class called VerifyTitle under src/test/java

package com.daz.crossbrowserTest.crossbrowserTest;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.safari.SafariDriver;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

public class VerifyTitle {
    WebDriver driver;
    static String CHROME_PATH="drivers/chromedriver";
    static String URL="http://www.google.lk";
    
    @Test
    @Parameters("browser")
    public void VerifyPageTitle(String BrowserName)
	{
		if(BrowserName.equalsIgnoreCase("Firefox"))
		{
			driver=new FirefoxDriver();
		}
		else if(BrowserName.equalsIgnoreCase("Safari"))
		{
			driver=new SafariDriver();
		}
		else if(BrowserName.equalsIgnoreCase("Chrome"))
		{
			System.setProperty("webdriver.chrome.driver", CHROME_PATH);
			driver=new ChromeDriver();
		}
		driver.manage().window().maximize();
		driver.get(URL);
		System.out.println(BrowserName+" : "+driver.getTitle());
		driver.quit();
	}

}

Make sure to create @Test and @Parameter annotations with TestNG

Our class is ready now. What Next?

We have to pass the browser to our test class. That is the place we do cross browsing.

Right Click on Class > TestNG > Convert to TestNG.

It will display “Refactoring” dialog box. There you can give a any name for the xml (I’m giving crossbrowsing.xml) and click Finish

Screen Shot 2015-09-16 at 10.50.14 PM    Screen Shot 2015-09-16 at 10.50.39 PM

Open the crossbrowsing.xml and add tests to the suite as below

<?xml version="1.0" encoding="UTF-8">
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
    <test name="FirefoxTest">
  	<parameter name="browser" value="Firefox"/>
  	<classes>
  		<class name="com.daz.crossbrowserTest.crossbrowserTest.VerifyTitle">
  	</classes>
  </test>
  <test name="SafariTest">
  <parameter name="browser" value="Safari"/>
  <classes>
  	<class name="com.daz.crossbrowserTest.crossbrowserTest.VerifyTitle"/>
  </classes>
  </test>
  <test name="ChromeTest">
  	<parameter name="browser" value="Chrome"/>
  	<classes>
  		<class name="com.daz.crossbrowserTest.crossbrowserTest.VerifyTitle"/>
  	</classes>
  </test>
</suite>

Here I explain what the <class name> in above xml. That is your test class name. You can give it as <package_name>.<class_name>.

Now you can run the test by right click on crossbrowsing.xml > Run As > TestNG Suite

Since this is sequential, it will run according to the order of browsers giving on crossbrowsing.xml.

In our example it will Firefox, Opera and Chrome. Here I add console output and TestNG output

Parallel

Now we can look how to do parallel test. Now it is easy 😉

Open crossbrowsing.xml file and do below change

<suite name="Suite" parallel="tests">

Save the xml

Right click on crossbrowsing.xml > Run As > TestNG Suite.

In this scenario all the browsers will open parallel. But you can see test results will differ from sequential order. Because fastest browser will finish the test first.  Here I attach my parallel test results as well.
