Introduction
TestNG stands for "Next Generation" and is an automation testing framework. JUnit, which uses annotations (@), inspired TestNG. TestNG addresses JUnit's shortcomings and is designed to make end-to-end testing simple. You can easily find out how many test cases are passed, failed, or skipped by using TestNG to generate a proper report. You can run the failed test cases on your own. In this article, we will be introducing TestNG and we will learn how to install it. So let us dive in!
TestNG
TestNG is a testing framework that aims to make a wide range of testing tasks easier to accomplish, from unit testing to integration testing.
TestNG is a testing framework that can be used with a variety of parameters. The test configuration is adaptable, and it comes with a robust execution model.
Additionally, TestNG supports annotations such as @BeforeCLass, @AfterClass, and others, which are very useful in the execution of test cases. It tries to cover all testing categories, such as unit testing, functional testing, and integration testing, among others.
Reports are also generated in HTML and XML formats.
It isn't necessary to extend any classes.
Despite the fact that Selenium is installed, both can run test cases in parallel. As a result, TestNG is a framework that covers all testing categories, provides annotations, and allows Selenium to work in tandem with it, resulting in the highest possible quality output.
A test is typically written in three steps:
Write your test's business logic and include TestNG annotations in your code.
In a testng.xml or build.xml file, add information about your test (such as the class name, the groups you want to run, and so on).
Run the TestNG.xml file.
Installation
We must first ensure that Selenium IDE is already installed before installing TestNG.
Step 1: Open Eclipse and select the Help tab from the top menu bar, then select 'Install New Software.'
Step 4: Once you've completed this, you'll be presented with the software that can be found at the above-mentioned URL. Select the checkbox that says "TestNG" and then click the "Next" button.
Step 5: Before starting the installation, the requirements and dependencies will be checked. If all of these conditions are met, TestNG will prompt you to install the software before proceeding. It will be installed successfully in the vast majority of cases.
Step 6: When this step is finished, it will prompt you to review the installation procedure. If everything appears to be in order, you can proceed by clicking 'Next.'
Step 7: To obtain the license, select "I accept the terms of the license agreement" and then "Finish."
Installation using Eclipse Marketplace
To complete the installation using this method, follow the steps below.
Step 1: Open Eclipse and select Help from the menu bar. Select Eclipse Marketplace from the drop-down menu.
Step 2: Search for TestNG in the Eclipse Marketplace and click the search button.
Step 4: The next dialogue box will be the License Agreement box, which can be accessed by pressing the Next button. Then click Finish after selecting 'I Accept the terms of the License Agreement.'
Step 5: If any warnings appear, dismiss them and click OK. After that, simply wait for the installation to finish.
Eclipse may then prompt you to restart. Yes can be selected.
Step 6: After Eclipse has been restarted, check to see if TestNG was successfully installed. You can check this by going to Window -> Preferences. TestNG must be included in the Preferences list in the list that is displayed.
You can now create your own TestNG class once the installation is complete. You can create a new TestNG class by going to File -> New -> TestNG in the select menu. If a Java file is already open, the Navigator will display all public methods for the Java File that is selected. You will have the option to select which ones you need to test. Every method selected on this page will be used to create a new TestNG class. The exception will be thrown if there is no implementation.
The next step verifies whether or not the file is being created. For configuration methods, it should have a default implementation. Java Client Driver for Selenium with TestNG After that, you can go ahead and download the Selenium Java Client Driver. You can run 'eclipse.exe' once the download is complete. The default workspace location should be used, or the browse option should be used to find the desired workspace location.
Configure Eclipse IDE
You can run eclipse.exe to find this file, which is stored in C:eclipseeclipse.exe.
After you've chosen a workspace, you can choose any location you want or stick with the default.
By going to File -> New -> Java Project, you can start a new project. You are free to name this project whatever you want. You can create a New Package after the project is completed. A new class can be created using this method.
Then go to the property for this class and select 'Java Build Path.'
Click Libraries and then 'Add External JARs' to get the external libraries.
Go to C:\selenium-2.25.0\ . It is possible to take all of the jars that are present at this location.
After importing all of the files, you'll have all of the Selenium Libraries you need to use with TestNG.
Frequently Asked Questions
Why use TestNG with Selenium? Default Selenium tests do not produce test results in a consistent format. We can generate test results in Selenium using TestNG.
What are the advantages of TestNG over JUnit? TestNG has three significant advantages over JUnit: - Annotations make things clearer. - It is easier to group test cases. - It is possible to test in parallel.
What is Annotation in TestNG? Annotations in TestNG are lines of code that control the execution of the method below them.
In TestNG, how do you write test cases? Step 1: Write your business logic and test it with TestNG annotations. Step 2: Fill in the blanks with more information, such as the name of the class, the names of the groups, the names of the packages, and so on. Step 3: Start the TestNG program.
What is TestNG Dataprovider? The TestNG Dataprovider is a way to pass parameters into the test function, allowing for multiple values in test cases to be passed in a single execution.
