Selenium Automation Testing using Java: Dependency on 'single' Test Methods , 'Multiple' test methods:

Dependency on 'single' Test Methods , 'Multiple' test methods:

In TestNG, dependencies between test methods can be defined using the dependsOnMethods attribute of the @Test annotation. This allows you to specify that a particular test method should only be executed if certain other test methods have been successfully executed.

package TestNGAsserionsBasics;

import org.testng.annotations.Test;

public class TestMethodWithDependency {

@Test

public void login()

{

System.out.println("in login ");

// add some excpetion and check

// throw new NullPointerException();

// Assert.assertTrue(false); // making this method failing

// it will check given value is true or not

// if given value is true- it will pass test method

// if given value is false -it will fail test method

}

// Define dependency for Test method=

// this test method depends on login test method,

//if login method is failing. it will not execute create order method

// it will skip createorder method

@Test(dependsOnMethods = "login")

public void createOrder()

{

System.out.println("createOrder ");

}
