Logic behind TestNG annotations

💡Let's take example to understand it:

If in class have 2 test methods i.e 

@Test(priority=0)

public void googleSearch()

{}

@Test(priority=1)

public void googleSearch1()

{}

Then, result would be below:

@BeforeSuite & @AfterSuite

It will execute only once before all test methods and after all test methods.

@BeforeClass & @AfterClass

It will execute only once before all test methods and after all test methods.

@BeforeMethod & @AfterMethod

It will execute before and after each test methods. Means in above scenario, 2 methods then 2 times before and after method will get executed.

@BeforeTest & @AfterTest

It will execute only once before all test methods and after all test methods.
