TestNG Annotations Order Example

Document Contents

Overview

In this tutorial, we will learn TestNG annotations order. In the earlier post, we had a look at some of the various TestNG annotations.

https://www.testingdocs.com/testng-annotations/

@BeforeSuite
This Before Suite Method is executed before any of the tests in the TestNG suite XML file.

@AfterSuite
This After Suite Method is executed after all the tests in the TestNG suite XML file are executed.

@BeforeTest
This Before Test method is executed before the first @Test annotated method in each test tag in TestNG suite XML file.

@AfterTest
This After Test method is executed after the last test method in the test tag in the suite XML file.

@BeforeClass
This Before Class method which is executed before the test methods inside a test class.

@AfterClass
This After Class Method is executed after all of the test methods inside a test class.

@BeforeGroups
This Before Groups Method is executed before execution of the tests belonging to the group specified in the ‘groups’ attribute.

@AfterGroups
This After Groups Method is executed after execution of all the tests belonging to the group specified in the ‘groups’ attribute.

@BeforeMethod
This Before Method is executed before each @Test annotated method.

@AfterMethod
This After Method is executed after each @Test annotated method.

TestNG Annotations Order – Example

To know the TestNG Annotations order of execution, we will write a test class with the annotations and run the test class using the testng.xml file.

testng.xml File

Copy Code

                    
<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
<!-- www.TestingDocs.com TestNG Tutorials -->
<suite name="TestingDocs Suite">
	<test name="TestOne">
		<classes>
			<class name="com.testingdocs.testng.tutorials
.TestNGAnnotationExecutionOrder">
			</class>
		</classes>
	</test>
</suite>

Run the TestNG Suite file. Right click on the testng.xml file and choose Run As >> TestNG Suite option in the context menu. The TestNG annotations order of execution is shown in the output.
