What is the purpose of the @BeforeClass annotation in TestNG?
A) To execute a method before all methods in a class
B) To execute a method after all methods in a class
C) To execute a method before each method in a class
D) To execute a method after each method in a class
Answer:
A) To execute a method before all methods in a class
Explanation:
The @BeforeClass annotation in TestNG is used to execute a method before all test methods in a class are run. This annotation is typically used for setup tasks that need to be performed before any test methods in the class are executed.
For example:
@BeforeClass
public void setUpClass() {
// Code to set up before all test methods in the class
}
In this example, setUpClass() will be executed once before any of the test methods in the class are run.
