Test Annotations | BeforeGroups | BeforeClass

Before and After Class

• @BeforeClass: This annotation is used to specify that a method should run before any of the test methods in the current class. Typically, it's used for setting up resources (e.g., opening a browser, setting up a database connection) that are needed for the entire test class.
• @AfterClass: This annotation is used to specify that a method should run after all the test methods in the current class have been executed. It's commonly used to clean up resources (e.g., closing a browser, releasing database connections).

Before and After Groups

• @BeforeGroups: This annotation is used to define a method that will be executed before any of the test methods in the specified group(s) are executed. It's often used to prepare the environment for a specific group of tests.
• @AfterGroups: This annotation is used to define a method that will be executed after all the test methods in the specified group(s) are executed. It’s useful for cleanup activities related to the group.

• @BeforeClass / @AfterClass: Run once before/after all methods in a test class.
• @BeforeGroups / @AfterGroups: Run before/after methods belonging to specific groups.
