What is the difference between BeforeTest and BeforeMethod in TestNG

Question

Both annotations runs before the @test in testNG then what is the difference between two of them.

Answer 1

I know there have already been several good answers to this question, I just wanted to build on them to visually tie the annotations to the xml elements in testng.xml, and to include before/after suite as well.
I tried to keep it as newbie friendly as possible, I hope it helps.

My java example is basically just a reformatted version of Ishita Shah's code.

BeforeAfterAnnotations.java (assumes this file is in a package called "test")

package test;

{
    @BeforeSuite
    public void beforeSuiteDemo()
    {
        System.out.println("\nThis is before a  start tag.");
    }


    @BeforeTest

        System.out.println("\tThis is before a  start tag.");
    }

    }
