TestNG Annotations - @BeforeTest

@BeforeTest is one of the TestNG Annotations. As the name defines, @BeforeTest is executed before the execution of all the @test annotated methods inside a TestNG Suite. This annotation allows developers to specify various actions to be taken before the execution of all the @test annotated methods inside a TestNG Suite.

Let’s understand the @BeforeTest annotation through an example.

Step 1: In the Maven project, create a TestNG Class that contains @BeforeTest.

Before_Test1.Java

Now, let’s explain what this code does:

• Package Declaration: Before_Test1 Class is on the com.geeksforgeeks.test package.
• Imports: Before_Test1 Class imports annotations and classes from the TestNG framework (org.testng.annotations.BeforeMethod and org.testng.annotations.Test).
• Before_Test1 Class: This is the main test class. It contains test methods and beforeTest method.

beforeTest (@BeforeTest):

• This method is annotated with @BeforeTest, indicating that it should be executed before test execution this suite contains many classes.
• It prints this "This method will be executed before the execution of all @Test annotated methods" statement.

Test Methods (@Test):

• Each test method is annotated with @Test, indicating that it is a test case.
• There are two test methods: test1() and test2().
• Each test method prints their respective statement.

After performing the operation, the result is printed to the console.

Step 2: Now, we create the AnnotationsTest.xml file to configure the Before_Test1 Class.

Step 3: Run the AnnotationsTest.xml. Right click on the AnnotationsTest.xml file, move the cursor down to Run As and then click on the TestNG Suite.
