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.
