TestNG Tutorial: What is, Annotations & Framework in Selenium (easy)

Creating TestNG Files

• To create a new TestNG file, right-click on the 'src/test/java' package folder.
• Alternatively, right-click on the 'src/test/java' package folder to create a new TestNG file.

TestNG Annotations

• The @Test annotation is used to specify a test case in TestNG.
• The SoftAssert class is used for verification operations in TestNG.

TestNG Reporting

• The index.html file is the report of the results of the most recent test run.
• The testng-failed.xml file in the test-output folder contains information about failed test cases.

TestNG Annotations Order of Execution

• The @BeforeSuite annotation block is executed first.
• The @BeforeTest annotation block is executed second.
• The @BeforeMethod annotation block is executed third.

Purpose of Annotations

• The @BeforeTest annotation is used to execute a method before the test.
• The @AfterTest annotation is used to execute a method after the test.
• The @Test annotation is used to specify a test case.
• The @BeforeSuite annotation is used to run a method before all tests in a TestNG suite have run.
• The @AfterSuite annotation is used to run a method after all tests in a TestNG suite have run.
• The @BeforeClass annotation is used to run a method before any test method belonging to the classes inside the tag is run.
• The @AfterClass annotation is used to run a method after all the test methods belonging to the classes inside the tag have run.
• The @BeforeMethod annotation is used to run a method before each test method.
• The @AfterMethod annotation is used to run a method after each test method.

TestNG Features

• TestNG provides support for data-driven testing, making end-to-end testing easy.
• TestNG handles failed test cases by providing information about the failures in the testng-failed.xml file.
• Advantages of using TestNG include support for data-driven testing and generation of test reports.
• TestNG allows the execution of the same test case multiple times without using loops using the dataProvider feature.
• Annotations in TestNG are used to specify the purpose of a method.

Integration with Other Tools

• Selenium Grid is more preferred for testers using TestNG.
• Selenium can be easily integrated with TestNG for test automation.
• TestNG provides support for generating test reports in Selenium using the index.html file.
