TestNG is a testing framework sparked from JUnit and NUnit but advancing some new functionalities that make it more robust and easier to use. TestNG include all levels of tests: unit, functional, end-to-end, integration, etc., and it requires JDK 5 or higher. <\/p>\n\n\n\n
TestNG Features<\/h2>\n\n\n\n
Supports Before and after annotations.<\/li>
Parameterization of test methods.<\/li>
Supports Data-Driven Testing using Data providers.<\/li>
Test cases can be arranged and prioritized easily.<\/li>
Supports threat safe environment when executing multiple threads.<\/li>
Easily integrate with various tools and plug-ins like build tools (Ant, Jenkins, Maven etc.), Integrated Development Environment (Eclipse).<\/li>
Facilitates user with effective means of Report Generation using ReportNG.<\/li>
Support for multi-threaded testing.<\/li><\/ul>\n\n\n\n
Installation and Setup<\/strong><\/h2>\n\n\n\n
If you are using Eclipse IDE, it\u2019s very easy to install TestNG. Below are the steps to install TestNG.<\/p>\n\n\n\n
Step 1: <\/strong>Launch eclipse IDE -> Click on the Help option in the menu -> Select \u201cEclipse Marketplace\u201d option in the dropdown.<\/p>\n\n\n\n<\/figure>\n\n\n\n
Step 2:<\/strong> Enter \u201cTestNG\u201d in the search field and click on the \u201cGo\u201d button.<\/p>\n\n\n\n<\/figure>\n\n\n\n
Step 3:<\/strong> Now, click on the Install button to install TestNG. <\/p>\n\n\n\n<\/figure>\n\n\n\n
So, After the Installation Eclipse would recommend you to restart in order to reflect the changes made. After restarting Eclipse, you can verify the TestNG installation. <\/p>\n\n\n\n
Go to Window->Preferences.<\/p>\n\n\n\n<\/figure>\n\n\n\n<\/figure>\n\n\n\n
TestNG: First Test<\/strong><\/h2>\n\n\n\n
Let us start with the creation of TestNG project.<\/p>\n\n\n\n
Step 1:<\/strong> Click on the File option in the menu -> Click on New -> Select Java Project.<\/p>\n\n\n\n<\/figure>\n\n\n\n
Step 2:<\/strong> Enter the project and click on the \u201cFinish\u201d button.<\/p>\n\n\n\n<\/figure>\n\n\n\n
Step 3:<\/strong> Configure the TestNG library inside the Java project. Go to “Configure Build Path” -> Click on the \u201cLibraries\u201d tab. Click on \u201cAdd library\u201d as shown below. <\/p>\n\n\n\n<\/figure>\n\n\n\n
Step 4:<\/strong> Now, select TestNG and click on the Next button. and, click on the Finish button.<\/p>\n\n\n\n
The TestNG is now added to the Java project. <\/p>\n\n\n\n
NOTE:<\/strong> Add all the JAR files inside the\u00a0selenium<\/strong>\u00a0and\u00a0libs<\/strong>\u00a0folders.<\/em><\/p>\n\n\n\n
Creating TestNG File<\/h2>\n\n\n\n
Step 1:<\/strong> Right-click the src<\/strong> folder of the Java Project and select New > Other\u2026<\/p>\n\n\n\n
Select TestNG class<\/strong> and then click Next<\/strong><\/p>\n\n\n\n<\/figure>\n\n\n\n
Step 2:<\/strong> Now, enter the Source folder, package name and the TestNG class name. Here, we can also select multiple TestNG notations.<\/p>\n\n\n\n<\/figure>\n\n\n\n
Click Finish<\/strong>. The template for your first TestNG file will be created with the default schema<\/p>\n\n\n\n
import org.testng.annotations.Test;\nimport org.testng.annotations.BeforeTest;\nimport org.testng.annotations.AfterTest;\n\npublic class NewTest {\n @Test\n public void f() {\n }\n @BeforeTest\n public void beforeTest() {\n }\n\n @AfterTest\n public void afterTest() {\n }\n\n}<\/pre>\n\n\n\n
The @Test<\/code> annotation is the root of TestNG test cases, tells that the method under it is a ‘test case’. Here, the method f<\/code> is a test case. <\/p>\n\n\n\n
The @BeforeTest<\/code> annotation tells that the method under it will be executed before the first test case. The @AfterTest<\/code> annotation tells that the method under it will be executed after the last test case.<\/p>\n\n\n\n
Let\u2019s now code an actual test code. In the following code snippet, we will be automating the sign-up flow<\/strong> using annotations.<\/p>\n\n\n\n
import org.testng.annotations.Test;\nimport org.testng.annotations.BeforeMethod;\nimport org.testng.annotations.AfterMethod;\nimport org.testng.annotations.BeforeClass;\n\nimport java.util.concurrent.TimeUnit;\n\nimport org.openqa.selenium.By;\nimport org.openqa.selenium.WebDriver;\nimport org.openqa.selenium.chrome.ChromeDriver;\nimport org.testng.annotations.AfterClass;\n\npublic class NewTest {\n\nWebDriver driver;\n\n@BeforeClass\npublic void testSetup()\n{\nSystem.setProperty("webdriver.chrome.driver", ".\\\\Driver\\\\chromedriver.exe");\ndriver=new ChromeDriver();\ndriver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);\ndriver.manage().window().maximize();\n\n}\n\n@BeforeMethod\npublic void openBrowser()\n{\ndriver.get("https:\/\/example.com\/");\ndriver.findElement(By.id("signup")).click();\nSystem.out.println("We are currently on the following URL" +driver.getCurrentUrl());\n}\n\n@Test(description="This method validates the sign up functionality")\npublic void signUp()\n{\ndriver.findElement(By.id("fullname")).sendKeys("John Doe");\ndriver.findElement(By.id("emailid")).sendKeys("johndoe@webkul.com");\ndriver.findElement(By.id("password")).sendKeys("demo123");\ndriver.findElement(By.id("submit")).click();\n\n}\n\n@AfterMethod\npublic void postSignUp()\n{\nSystem.out.println(driver.getCurrentUrl());\n\n}\n\n@AfterClass\npublic void afterClass()\n{\ndriver.quit();\n}\n\n}<\/pre>\n\n\n\n
Execute the TestNG script<\/strong><\/h2>\n\n\n\n
In order to run the test, follow the below steps:<\/p>\n\n\n\n
Right-click the NewTest folder and Select Run as<\/strong> > TestNG Test<\/strong>:<\/p>\n\n\n\n<\/figure>\n\n\n\n
The results of the test will be displayed into two windows the console window and in the TestNG results window:<\/p>\n\n\n\n<\/figure>\n\n\n\n<\/figure>\n\n\n\n
To generate the HTML report<\/strong><\/h2>\n\n\n\n
Right-click the Project<\/strong> and select Refresh<\/strong>. A test-output folder will be created:<\/a><\/li>
