Execute selenium webdriver testng.xml using Maven

We can execute our tests using maven Surefire plug-in. This plug-in is used during the test phase of software build lifecycle to execute tests. To configure Surefile Plug-in, we need to add the snippet as below in pom.xml file. And also we need to add TestNG dependency to the pom.xml file.

To get started with TestNG, we need to include the following dependency in our project configuration file Pom.xml

 <dependency>
   	<groupId>org.testng</groupId>
      	<artifactId>testng</artifactId>
      	<version>6.9.x</version>
      	<scope>test</scope>
 </dependency>

To run selenium tests, we need to include following dependency to pom file :

<dependency>
<groupId>org.seleniumhq.selenium</groupId>
	<artifactId>selenium-java</artifactId>
	<version>2.xx.x</version>
</dependency>

To execute tests over multiple machines / virtual machines, we need to include Selenium server into your maven project, you need to add the following dependency to your pom.xml.

   <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-server</artifactId>
        <version>3.0.1</version>
    </dependency> 

After adding dependencies, navigate to project directory and run maven command from command-line which downloads all dependencies and adds them to the project.
mvn clean install

We have to include, maven-compiler-plugin and maven-surefire-plugin to the configuration file Pom.xml

Maven-compiler-plugin: Compiler-plugin is used to compile the sources of our project

	<plugin>
		<groupId>org.apache.maven.plugins</groupId>
		<artifactId>maven-compiler-plugin</artifactId>
		<version>3.5.1</version>
			<configuration>
				<source>${jdk.level}</source>
				<target>${jdk.level}</target>
			</configuration>
	</plugin>

Maven-surefire-plugin: Surefire-plugin is responsible for running tests that are placed in test source directory /src/test/java.

	<plugin>
		<groupId>org.apache.maven.plugins</groupId>
		<artifactId>maven-surefire-plugin</artifactId>
		<version>2.19.1</version>
			<configuration>
				<suiteXmlFiles>
				<!-- TestNG suite XML files -->
					<suiteXmlFile>testng.xml</suiteXmlFile>
				</suiteXmlFiles>
			</configuration>
	</plugin>

By default, Surefire-plugin runs all tests that matches with filename pattern such as *Test.java in test source directory src/test/java . To use a different naming scheme, we can configure Surefire Plugin which includes parameter and specify the tests that we want to include.

Let us now create a simple example using selenium, testNG and execute with the help of Maven.

Step 1: First create a maven project and name it as 'FirstDemo'.
Step 2: Create a class 'GoogleHomePageTest.java'
Step 3: Add Tests in 'GoogleHomePageTest.java' class.
Step 4: Add TestNg and Selenium Dependencies to maven pom.xml file.
Step 5: Now add maven Surefire Plug-in to pom.xml
Step 6: Execute tests using 'mvn test' from command prompt.

The below is the Project structure after creating as above steps.
maven Testng Java project

The below is the example program to execute testng.xml file using maven.

package com.google.tests;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class GoogleHomePageTest {
	
	private WebDriver driver; 
	String appURL = "http://google.com";

	@BeforeClass
	public void testSetUp() {
		
		driver = new FirefoxDriver();
	}
	
	@Test
	public void verifyGooglePageTittle() {
		driver.navigate().to(appURL);
		String getTitle = driver.getTitle();
		Assert.assertEquals(getTitle, "Google");
	}
	
	@AfterClass
	public void tearDown() {
		driver.quit();
	}
	
}

We have a test 'verifyGooglePageTitle()' in the above class. Below is the testng.xml file which we will include in pom.xml file.

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Example test run">
  <test name="Simple Test">
    <classes>
      <class name="com.google.tests.GoogleHomePageTest"/>
    </classes>
  </test>
</suite>

After adding all the dependencies, we need to add the classes that we want to execute. And below is the pom.xml file looks like.

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>FirstDemo</groupId>
	<artifactId>FirstDemo</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<properties>
		<jre.level>1.7</jre.level>
		<jdk.level>1.7</jdk.level>
	</properties>

	<build>
		<plugins>
			<!-- Compiler plug-in -->
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<source>${jdk.level}</source>
					<target>${jdk.level}</target>
				</configuration>
			</plugin>
			<!-- Below plug-in is used to execute tests -->
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-surefire-plugin</artifactId>
				<version>2.18.1</version>
				<configuration>
					<suiteXmlFiles>
						<!-- TestNG suite XML files -->
						<suiteXmlFile>testng.xml</suiteXmlFile>
					</suiteXmlFiles>
				</configuration>
			</plugin>
		</plugins>
	</build>
	<!-- Include the following dependencies -->
	<dependencies>
		<dependency>
			<groupId>org.seleniumhq.selenium</groupId>
			<artifactId>selenium-java</artifactId>
			<version>2.45.0</version>
		</dependency>
		<dependency>
			<groupId>org.testng</groupId>
			<artifactId>testng</artifactId>
			<version>6.8.8</version>
		</dependency>
	</dependencies>

</project>

After executing the above program, the report will be generated in your project folder under target\surefire-reports. You can checkout default testng html reports.

Hope the above example works for you. Please let us know if you face any problem.

Hello Team,

Thank for the such a fantastic website.
I do have a doubt in this topic"Execute selenium webdriver testng.xml using Maven".
I have created a maven project, now how to create testNG.xml? and where to put it in folder

Simply you need to right click on the project and create a file and give it to name testng.xml.
It will be shown in your project structure.

Same way you can install TestNG the way you installed Maven either from Eclipse Marketspace or from Install new software. once you install TestNG, refresh your project and you will see one testng.xml.

I just started working with maven, and very soon i understand the importance of POM.XML. Many thanks for your explaination to link tests with pom.

Hi, thanks for great tuttorial. Could we create a executable to run the program? Example:
# java -jar FirstDemo.jar

hi,
i understood the concept,but liitle bit confused

@Admin: Can you also suggest command line way of execution . What should be -cp value for java / testng libraries

[ERROR] No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>.

When I run the file I get an exception: java.lang.NoClassDefFoundError: org/testng/remote/RemoteArgs.

Could anyone please help me with this issue?
