TestNG Interview Questions and Answers
Ques 16. Explain the purpose of the 'alwaysRun' attribute in TestNG annotations.
The 'alwaysRun' attribute, when set to 'true' in TestNG annotations, ensures that the annotated method (such as @BeforeMethod or @AfterMethod) always runs, even if the test method fails.
Ques 17. How can you perform cross-browser testing in TestNG?
Cross-browser testing in TestNG can be achieved by parameterizing the browser type and using the @Parameters annotation or the dataProvider attribute to supply different browsers to the test method.
Ques 18. What is the purpose of the IRetryAnalyzer interface in TestNG?
The IRetryAnalyzer interface in TestNG allows you to implement custom logic to decide whether a test method should be retried after a failure. It is used in conjunction with the @Test annotation's 'retryAnalyzer' attribute.
Ques 19. Explain the concept of testng.xml in TestNG.
The testng.xml file in TestNG is an XML configuration file that defines the structure and parameters for test execution. It allows you to customize the test suite, set parameters, and configure test groups.
Ques 20. What is the purpose of the @Listeners annotation in TestNG?
The @Listeners annotation in TestNG is used to specify one or more listener classes that will be notified during the test execution. This allows you to implement custom behavior at various stages of the test lifecycle.
