Common annotations used in different test classes

Question

I have a question regarding annotations like @BeforeTest or @BeforeMethod. Is it possible to set a global annotations, so that all my test classes will be use them? I have in my framework over 20 test classes with a lot of test methods. Every test class has preconditions like @BeforeTest or @BeforeMethod, but for each test class this preconditions are the same. So I think this might be a good idea, to write a common annotations methods, which could be used in every test class.

Answer 1

Make the code reusable using inheritance. Create a super class DefaultTestCase:

public class DefaultTestCase{
  @BeforeTest
  public void beforeTest() {
     System.out.println("beforeTest");
  }  
  @BeforeMethod
  public void beforeMethod() {
    System.out.println("beforeMethod");
  }  
}

and each test case class extends the DefaultTestCase:

public class ATest extends DefaultTestCase{
  @Test
  public void test() {
     System.out.println("test");
  }
  @Test
  public void anotherTest() {
     System.out.println("anotherTest");
  }
}

Output:

beforeTest
beforeMethod
test
beforeMethod
anotherTest

Using an implementation of ITestListener and IClassListener, you could do as below. onTestStart would be invoked before each test case and onStart would be invoked for <test> in your suite and onBeforeClass is executed once for each class.

public class MyListener implements ITestListener, IClassListener {
    
    @Override
    public void onStart(ITestContext context) {
        // Put the code in before test.
        beforeTestLogic();
    }

    @Override
    public void onBeforeClass(ITestClass testClass) {
        // Put the code in before class.
        beforeClassLogic();
    }

    @Override
    public void onTestStart(ITestResult result) {
        // Put the code in before method.
        beforeMethodLogic();
    }
}

Now add the @Listener annotation to the required test classes:

@Test
@Listener(MyListener.class)
public class MyTest {
    // ........
}
