Class level annotations in TestNG

TestNG has great feature to define annotations on a class instead of a each test method.

If say suppose there are 10 test methods, where adding @Test on a class level is simpler than adding @Test for each method.

When we make class level @Test annotation, all the public methods of this class will become test methods even if they are not annotated.

We can still define @Test annotation on of the method if we want to add any attributes to particular test method.

NOTE: In the same way, we can also define groups "ex: @Test(groups = { "regression" })" at the class level and
then add groups at the individual method level:

Below is the sample program using @Test annotation at class level:

package com.example.classlevel;

import org.testng.annotations.Test;

@Test
public class ClassLevelAnnotations {

        @Test
	public void methodOne() {
		System.out.println("Helloo.. Im in method adding numbers");
	}

        @Test
	public void MethodTwo() {
		System.out.println("Helloo.. Im in method divided by zero");
		int e = 1 / 0;
	}

	@Test(dependsOnMethods={"MethodTwo"})
	public void methodThree() {
		System.out.println("Helloo.. Im in method skip");
	}
}

In the above example we have added @Test annotation only to the last method with attribute 'dependsOnMethods'. methodThree() will be skipped as it depends on MethodTwo() which is failed due to ArithmeticException.

The below is the output:

Helloo.. Im in method divided by zero
Helloo.. Im in method adding numbers
PASSED: methodOne
FAILED: MethodTwo
java.lang.ArithmeticException: / by zero
	at com.example.classlevel.ClassLevelAnnotations.MethodTwo(ClassLevelAnnotations.java:14)
......
	at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:175)

SKIPPED: methodThree

Comments

Hi,
I got a different when performing this:
TestNGPackage.DemoFour.methodThree() is depending on method public void TestNGPackage.DemoFour.methodTwo(), which is not annotated with @Test or not included.

Am I doing something wrong?
