What Is TestNG Annotations-Benefits, Hierarchy

What Is TestNG Annotations- Its Benefits, Hierarchy & TestNG Case Priorities?

Annotations generally represent a note or a comment on a diagram, etc., to convey its meaning. TestNG also uses them for the exact reason. TestNG annotations are the code written inside your source test code logic to manage the flow of the execution of tests? Therefore, it is vital to annotate your processes in TestNG to execute the tests. TestNG will ignore the process that does not contain an annotation since it won't know when to run it.

Annotations in TestNG can be comprehended as distinct pieces of code integrated within the logic of a program to manage the sequential execution of the test methods. In other words, TestNG Annotations assist in deciding the sequence of the tests made to execute. These annotations are extracted from Java language and are a critical component of Test Next Generation (TestNG), an automation framework that Selenium uses.

A TestNG annotation begins from the symbol "@," and the annotation name follows after that. Apart from the header file and '@' symbol, you require nothing to execute TestNG annotations.

Different Kinds Of TestNG Annotations

In TestNG, there are ten kinds of annotations:

@BeforeSuite – In TestNG, the @BeforeSuite method executes before all other test methods.@AfterSuite – In TestNG, the @AfterSuite method runs after all other test methods have been completed.@BeforeTest – The @BeforeTest function in TestNG runs before all of the test methods in that folder are executed.@AfterTest – TestNG's @AfterTest function runs after all test methods in a folder are executed.@BeforeClass – In TestNG, the @BeforeClass function runs before the first method collects the current class.@AfterClass – In TestNG, the @AfterClass method is called after all of the current class's test methods have been completed.@BeforeMethod – In TestNG, the @BeforeMethod method executes before each test method.@AfterMethod – In TestNG, the @AfterMethod method executes after each test method is run.@BeforeGroups – In TestNG, the @BeforeGroups method runs before the test cases in that group run. It only executes once.@AfterGroups – The @AfterGroups function in TestNG executes after the test cases in that group have been run. It is only used once.https://www.devlabsalliance.com/courses/certified-sdet-professional/
