Next generation java testing testng free download

In this tutorial of three articles, my goal is to share knowledge regarding Test Next Generation (Test NG). Test NG is a powerful Test Framework for testing Java code. A Test Framework is a pattern for writing and running Test Scripts. Thanks to x Unit, we have a family of frameworks for testing many programming languages. Test NG is not a part of x Unit but was influenced by x Unit. JUnit, NUnit, and Py Unit are some of the frameworks within the x Unit family. JUnit is the de facto standard for Java while NUnit is the framework for C# and Py Unit is the framework for Python. However, in the beginning, there were limitations with the x Unit family. For example, JUnit 3 had the following constraints: As a result of the limitations, Test NG was created and added more features. In return, JUnit 4 embraced Test NG’s features then added some of those same features. Hopefully you can learn and apply a new feature whether you are using Test NG or another Test Framework. By the end of this tutorial, you will know: Test Frameworks are important because it facilitates the testing process. It facilitates the testing process by allowing us to write a quick test using Annotations and Assertions. In addition, we can execute a single Test Script or a collection of Test Scripts in a Test Suite. Experienced Automation Engineers can leverage a Test Framework to design a Page Object Model and create Automation Design Frameworks. A Page Object Model is a design pattern while Automation Design Frameworks can be applied to most automation endeavors such as Selenium and UFT formerly known as QTP. Three of the most popular Automation Design Frameworks are Data Driven Frameworks, Keyword Driven Frameworks, and Hybrid Driven Frameworks. The following are four core functions of a Test Framework: We can install Test NG using an IDE (Eclipse, Net Beans, Intelli J), Build Tool (Maven, Gradle, Ant), Command Line, or Download the Test NG jars. Accept Terms Annotations support Test NG by controlling the execution flow of our program. For scalability, a Build Tool is the preferred way to install Test NG. They are written above their respective method and prefixed with an at “@” symbol. However, Eclipse Marketplace is one of the fastest ways to install Test NG. We can place an Annotation anywhere on the editor because it’s automatically connected to the method. In this section, we’ll cover the Configuration Annotations and Test Annotation. Configuration Annotations are like Pre-Conditions and Post-Conditions. A Pre-Condition is executed before our test and a Post-Condition is executed after our test. The following screenshot lists each Configuration Annotation: All @Before Annotations help us configure and set up our test. For example, we can set the system property, load the browser, and load the Application Under Test (AUT) in a @Before Annotation. The @After Annotations provide a way to clean up important things like quitting the driver after our test. Here’s a code snippet for @Before Method and @After Method: A Test Annotation is written as @Test and identifies our method as a Test Method. We have the option of marking our methods or entire class with @Test. After executing our test, the Console and Results tab only show results for public methods. Other methods such as default or private are allowed to be annotated with @Test but will not execute as a Test Method. The following code snippet shows an example of 3 Test Methods annotated with @Test: In our program, the @Before Configuration Annotation(s) always execute first. Next, is the Test Method(s) followed by the @After Configuration(s). We have the ability to add multiple Configuration Annotations and/or Test Methods. A Test Requirement determines which annotations we choose for our Test Script. Here’s a description of each Configuration Annotation in their hierarchy order (from highest to lowest): The xml file provides a picture regarding each Configuration Annotation execution order. However, it does not provide a picture regarding the Test Method’s execution order. By default, the Test Methods execute in alphanumeric order. Therefore, the execution order runs each Test Method in the following order: Test NG identifies the methods by looking up its annotation. As a result, we are allowed to set a priority for each Test Method by implementing an attribute. The @Test Annotation has a total of 24 attributes with the priority attribute establishing a specific execution order. Here’s an example of each @Test Annotation with a priority attribute: Test NG has more than 50 Assertion methods that verify whether our test Pass or Fail. All of them are included in a package called org.testng. The assertion methods are overloaded versions of the following: Each Assertion contains the same signature whereby the first parameter is an actual result, the second parameter is an expected result, and the third parameter is an optional String value. The String value will only be shown if the Assertion Fails. Test NG provides two types of Assertions: Hard Assertions and Soft Assertions. Let’s take a look at the difference between both Test NG Assertions. A Hard Assertion stops executing a Test Method soon as an Assertion Fail. We begin Hard Assertions by writing Assert then the dot (.) operator. After writing the dot operator, a list of assertion methods are visible in the editor. The following screenshot and code snippet display Test Project’s Home page after logging into their application and four Hard Assertions: Notice, two Assertions Fail. The first Assertion encloses a different actual and expected result while the third Assertion returns false for the assert True method. In our Test Report, we should see two Fail Assertions. However, the Test Report displays only one assertion from the first Assertion. The Test Report returned one Assertion because Hard Asserts are designed to exit a Test Method after its first Assertion failure. A Soft Assertion continues executing the Test Method after an Assertion failure. As a result, the remaining Assertions are never executed to verify if they Passed or Failed. Other Test Frameworks do not have a Soft Assertion feature but can plug in a similar feature. First, we declare the Soft Assert class then utilize the softassert object. Notice, the last line contains a method called assert All. The purpose of assert All is to receive all Assertion Errors if there is a failure. The following screenshots show an accurate report after executing the same Test Script with Soft Assert. Both Assertions show up because they Fail the verification step. Soft Assertions are beneficial for Test Methods with multiple verification steps. However, there are situations when it’s more efficient to implement a Hard Assertion. For example, we should consider a Hard Assertion if the application does not open. There isn’t a need to continue executing if the application fails to open. Therefore, it’s best to utilize Soft Assertions as well as Hard Assertions in our program. In this first tutorial we’ve covered why Test Frameworks are important, what are the core functions of a Test Framework, talked about configuration and test annotations and learned all about hard and soft assertions.
