As per the names, BeforeMethod and AfterMethod annotations get executed for each test method/case in a class file.
Please note, that methods defined under @BeforeMethod and @AfterMethod are not considered as Test Cases. The result would be generated according to the methods defined under @Test annotations only.
BeforeMethod and AfterMethod
Sample program to understand the usage of these annotations.
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;
/**

* Sample program to understand the usage of @BeforeMethod and @AfterMethod.
*/
public class BeforeAfterMethod
{
@BeforeMethod
public void login()
{
System.out.println("User logged in to website.");
}
@Test(priority=1)
public void getBlogsCount()
{
System.out.println("Extract total count of blogs.");
}
@Test(priority=2)
public void myProfile()
{
System.out.println("User Profile get opened.");
}
@Test(priority=3)
public void search()
{
System.out.println("Search Result get populated.");
}
@AfterMethod()
public void logout()
{
System.out.println("User Logged out from the website.");
}
}
- In the above console output, observe below points:
- The sequence of execution in format @BeforeMethod > @Test > @AfterMethod
- The total number of test cases would be the same as the number of @Test annotations.
- If the result of BeforeMethod is FAIL then rest of the Test Cases get SKIPPED.
Working Example
Let’s think about a scenario where we have to test a few functionalities on a website. And for each test case, we have to launch the browser and Close the browser. So, the dry run of the program would be like:
- Test Case 1:- Launch the browser and URL > Check Profile of the author > Close browser
- Test Case 2:- Launch the browser and URL > Get blogs count on the page > Close browser
- Test Case 3:- Launch the browser and URL > Validate Search Functionality > Close browser
