In TestNG, @BeforeTest and @AfterTest are annotations used to define methods that should run before and after the execution of any test methods in the specified test tag in the TestNG XML file. These annotations help set up and clean up resources needed for tests.
@BeforeTest
The ‘@BeforeTest‘ annotation is used to identify methods that should run before any test method in the current ‘<test>‘ tag is executed. It is typically used for setting up configurations or initializing resources required for the tests.
Example of @BeforeTest
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import org.testng.annotations.AfterTest;
public class SampleTest {
@BeforeTest
public void setUp() {
System.out.println("Setting up the test environment");
// Code to set up the test environment, e.g., initialize WebDriver
}
@Test
public void testMethod1() {
System.out.println("Executing test method 1");
// Test logic here
}
@Test
public void testMethod2() {
System.out.println("Executing test method 2");
// Test logic here
}
@AfterTest
public void tearDown() {
System.out.println("Cleaning up the test environment");
// Code to clean up after tests, e.g., close WebDriver
}
}
Explanation
‘
@BeforeTest setUp()‘:- This method will run before any test methods in the
<test>tag of the XML file. - It’s used to set up the environment or initialize resources needed for the tests, such as WebDriver initialization in Selenium.
- This method will run before any test methods in the
Test Methods:
testMethod1andtestMethod2are the actual test methods.- These methods contain the test logic and will run after the
@BeforeTestmethod.
@AfterTest tearDown():- This method will run after all the test methods in the
<test>tag have been executed. - It’s used to clean up the environment or release resources used during the tests, such as closing the WebDriver.
- This method will run after all the test methods in the
XML Configuration
To see the full effect of ‘@BeforeTest‘ and ‘@AfterTest‘, you should configure the TestNG XML file to define your tests.
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite1">
<test name="Test1">
<classes>
<class name="SampleTest"/>
</classes>
</test>
</suite>
Usage in Selenium
To see the full effect of ‘@BeforeTest‘ and ‘@AfterTest‘, you should configure the TestNG XML file to define your tests.
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import org.testng.annotations.AfterTest;
public class SeleniumTest {
WebDriver driver;
@BeforeTest
public void setUp() {
System.out.println("Initializing WebDriver");
System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("https://example.com");
}
@Test
public void testMethod1() {
System.out.println("Executing test method 1");
// Perform test actions on the web page
}
@Test
public void testMethod2() {
System.out.println("Executing test method 2");
// Perform test actions on the web page
}
@AfterTest
public void tearDown() {
System.out.println("Closing WebDriver");
if (driver != null) {
driver.quit();
}
}
}
Explanation for Selenium
‘
@BeforeTest setUp()‘:- Initializes the WebDriver before any test method is executed.
- Maximizes the browser window and navigates to a specific URL.
Test Methods:
- Contains the logic to interact with the web page.
‘
@AfterTest tearDown()‘:- Closes the WebDriver after all the test methods have been executed to ensure proper cleanup.
Using @BeforeTest and @AfterTest helps to ensure that your test environment is properly set up before the tests run and cleaned up afterwards, which is crucial for maintaining a stable and consistent testing process.
