@BeforeClass method execution in TestNG during inheritence

Question

I have just started using TestNG, and I had a question in mind. If class A has a @BeforeSuite method and class B is inheriting class A like in the below example:

class A file:

class A
{
  @BeforeSuite
  public void beforeTest()
  {
    //something
  }
}

class B file:

class B extends A
{
 @Test
 public void executeTest()
 {
  //something
 }
}

So, in this scenario, the @BeforeSuite from class A will run for sure when I try and execute ClassB:executeTest() . Is there any way I could disable the @BeforeSuite method from running, without excluding the inheritance or disabling the @Test method?

Answer 1

You can override method like in example below. @BeforeSuite of the base class will not be executed in this case.

TestA:

import org.testng.annotations.BeforeSuite;
import org.testng.log4testng.Logger;

public class TestA {
    protected static Logger LOGGER = Logger.getLogger(TestA.class);

    @BeforeSuite
    public void beforeSuite() {
        LOGGER.warn("beforeSuite - TestA");
    }
}

TestB:

import org.testng.annotations.BeforeSuite;
import org.testng.annotations.Test;

public class TestB extends TestA {

    @BeforeSuite
    public void beforeSuite() {
        LOGGER.warn("beforeSuite - TestB");
    }

    @Test
    public void executeTest() {
        LOGGER.warn("executeTest - TestB");
    }
}

Run TestB and check output:

[TestA] [WARN] beforeSuite - TestB
[TestA] [WARN] executeTest - TestB
