TestNG Beginner's Guide

By: Varun Menon

Overview of this book

<p>Unit/Functional testing has now become part of every development life cycle. Junit was once the main framework that was used by developers for the purpose of Unit testing when it came to Java. But Junit had certain limitations in terms of execution and features. This book explains about the features and usage of TestNg, a new framework that overcomes Junit’s limitations and provides a lot of extra features.</p> <p>TestNg Beginner’s Guide is a practical, hands-on guide that aims to increase your knowledge of TestNg. This step-by-step guide will help you to learn and understand the different TestNg features, and you will learn about the advantages and how to use and configure each feature according to your needs. <br /><br />This book explains the various features of the TestNG testing framework. It provides a step-by-step guide that explains the different features with practical examples and sample programs.You will also learn about how to use and configure each feature based on different test scenarios. We will also take a look at extending TestNG to add custom logging and test-reports. If you are a beginner in TestNG or test frameworks, then this book will help you in learning, practising, and getting started with TestNg.</p>

Time for action – DataProvider in different class


  1. Open Eclipse and add two new classes with the names DataProviderClass and TestClass to the Java project created earlier.

  2. Add the following code to TestClass:

    package test.dataprovider;
    
    import org.testng.annotations.Test;
    
    public class TestClass {
      
      @Test(dataProvider = "data-provider",dataProviderClass=DataProviderClass.class)
      public void testMethod(String data) {
        System.out.println("Data is: " + data);
      }
    
    }

    The preceding test class contains a test method which takes one argument as input and prints it onto the console when executed. The DataProvider to provide parameter values to a test method is defined by giving the name of the DataProvider using the DataProvider attribute while using Test annotation. As the DataProvider method is in a different class, the class name to refer for getting the DataProvider is provided to TestNG using the dataProviderClass attribute as seen in the preceding code.

  3. Add the following code to DataProviderClass...
