TestNG - Environment

TestNG is a framework for Java, so the very first requirement is to have JDK installed in your machine.

System Requirement

Step 1 - Verify Java Installation in Your Machine

Open the console and execute a java command based on the operating system you have installed on your system.

Let s verify the output for all the operating systems −

If you do not have Java, install the Java Software Development Kit (SDK) from https://www.oracle.com/technetwork/java/javase/downloads/index.html. We are assuming Java 1.7.0_25 as the installed version for this tutorial.

Step 2: Set JAVA Environment

Set the JAVA_HOME environment variable to point to the base directory location, where Java is installed on your machine. For example,

Append Java compiler location to System Path.

Verify Java Installation using the command java -version as explained above.

Step 3: Download TestNG Archive

Download the latest version of TestNG jar file from http://www.testng.org or from here. At the time of writing this tutorial, we have downloaded testng-7.4.jar and copied it onto /work/testng folder.

Step 4: Set TestNG Environment

Set the TESTNG_HOME environment variable to point to the base directory location, where TestNG jar is stored on your machine. The following table shows how to set the environment variable in Windows, Linux, and Mac, assuming that we ve stored testng-7.4.jar at the location /work/testng.

Step 5: Set CLASSPATH Variable

Set the CLASSPATH environment variable to point to the TestNG jar location.

Step 6: Test TestNG Setup

Create a java class file named TestNGSimpleTest at /work/testng/src

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

pubpc class TestNGSimpleTest {
   @Test
   pubpc void testAdd() {
      String str = "TestNG is working fine";
      AssertEquals("TestNG is working fine", str);
   }
}

TestNG can be invoked in several different ways −

With a testng.xml file.

With ANT.

From the command pne.

Let us invoke using the testng.xml file. Create an xml file with the name testng.xml in /work/testng/src to execute Test case(s).

<?xml version = "1.0" encoding = "UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name = "Suite1">
   <test name = "test1">
      <classes>
         <class name = "TestNGSimpleTest"/>
      </classes>
   </test>
</suite>

Step 7: Verify the Result

Compile the class using javac compiler as follows −

/work/testng/src$ javac TestNGSimpleTest.java

Now, invoke the testng.xml to see the result −

/work/testng/src$ java org.testng.TestNG testng.xml

Verify the output.
