TestNG: Run Test suite from xml file

In TestNG, you can group test classes in a <test> element and all the <test> elements can be grouped in a suite file.

suiteDemo.xml

<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd" >

<suite name="sanity test suite">

 <test name="Sanity test 1">
  <classes>
   <class name="com.sample.app.arithmetic.TestClass1"></class>
   <class name="com.sample.app.arithmetic.TestClass2"></class>
  </classes>
 </test>

 <test name="Sanity test 2">
  <classes>
   <class name="com.sample.app.arithmetic.TestClass3"></class>
   <class name="com.sample.app.arithmetic.TestClass4"></class>
  </classes>
 </test>

</suite>

Define ‘suiteDemo.xml’ file in the same package where your test classes exist.

As you see the xml, this test suite has two test elements. First test element groups the test classes TestClass1 and TestClass2. Second test element groups the test classes TestClass3 and TestClass4.

BaseTest.java

package com.sample.app.arithmetic;

 public void beforeSuite_2() {
  System.out.println("Inside beforeSuite_2\n");
 }

 @AfterSuite

  System.out.println("\nInside afterSuite_1");
 }

 @AfterSuite
 public void afterSuite_2() {
  System.out.println("Inside afterSuite_2");

How to run the test suite file?

Right click on the xml file.

Run As -> TestNG Suite.

You will get below messages in console.
