Overview

In this tutorial, we will learn to run tests from the TestNG Suite testng.xml. The default test suite in TestNG is testng.xml. We can create TestNG test suites using the XML files.  Let’s create sample TestNG test methods and run them using the TestNG testng.xml suite file.

Create testng.xml

Right click in the Package explorer >> New >> File.

Create a new testng.xml file to the project and add the test classes information.

<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
<suite name="First Suite" verbose="1" >
 <test name="My First TestNG Test" >
 <classes>
 <class name="com.testingdocs.testng.tutorial.SampleTestClass" >
 <methods>
 <include name="testMethod1"/>
 </methods>
 </class>
 </classes>
 </test>
 <test name="My Second TestNG Test" >
 <classes>
 <class name="com.testingdocs.testng.tutorial.SampleTestClass" >
 <methods>
 <include name="testMethod2"/>
 </methods>
 </class>
 </classes>
 </test>
</suite>

Run TestNG tests

To run the tests in Eclipse, right-click on the TestNG Suite file, choose

Run As >> TestNG Suite
