Learn how to design a test automation framework for automating web-based applications.

Test Automation

Testing the user interface for any application is generally time-consuming when done for each new release. UI test automation is the most common and effective way to simulate the actual user journey and business use cases for any application.

In this module, we’ll learn to design a test automation framework from scratch to automate any web-based application using Java, Selenium, and TestNG. We’ll start by learning the basics of Selenium and TestNG and then learn about build management, logging, and reporting, all of which are key concepts for any QA engineer or developer. By the end of this module, we will successfully create a UI test automation framework.

Design a Test Automation Framework with Selenium and Java

# Introduction 

**TestNG** is an easy-to-use testing framework written in Java, designed for unit, functional, and end-to-end integration tests providing many functionalities. Many plugins are integrated with TestNG.

Writing tests with TestNG is very simple. Write the business logic inside a method. Then annotate the method with `@Test`. Add metadata about the test inside `@Test` like *description*, *group*, *priority*, *enabled*, etc. This process will be covered in the [next lesson](https://www.educative.io/courses/test-automation-framework-selenium-java/testng-annotations).

# About testng.xml

***testng.xml*** is a file that contains the test configuration, and it allows us to organize test classes and define test suites and tests. 

Please find a sample TestNG class below:

```java
package com.example.tests;

import org.testng.Assert;
import org.testng.annotations.Test;

public class TestClass {

	@Test // is an annotation to indicate this is a test method
	public void testA() {
		Assert.assertTrue(true); 
	}

	@Test
	public void testB() {
		Assert.fail();
	}
}

```

To define this class in a ***testng.xml***:

```xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Sample Test Suite">

    <test name="Sample Test">
        <classes>
            <class name="com.example.tests.TestClass">
            </class>
        </classes>
    </test>
</suite>
```

Not everything is mandatory. The bare minimum is having a `suite` tag with at least one `test` tag, containing at least one *packages* or a *classes* tag as shown in the above XML.
