While executing the Testng framework the user wants to generate the customised reports after each test case execution.Which class is used from the below

While executing a TestNG class from an XML file, one group got included in
execution which does not exist. What will happen with the execution?

Arrange the below tags from parent to child?

a)<test>
<suite>
<class>
<methods>
<classes>

b)<suite>
<class>
<class>
<methods>
<classes>

c)<suite>
<test>
<classes>
<class>
<methods>

d)<suite>
<classes>
<test>
<class>
<methods>

Can we generate the Junit Report for the test cases generated in TestNG ?

What is the main node that contains everything in the configuration file for our tests?

Consider an XML file to execute a TestNG class. If the tag is empty
whereas group names are included in tag, what will be the result of the
execution of this XML file?

Inorder to execute the script parallely on different browsers,@Before method should be run with which of the below annotation.

Consider following two classes:

public class BaseClass {
@BeforeSuite
public void beforeSuite() {....}
@AfterSuite
public void afterSuite() {....}
@Test
public void f() {....}
}
public class Derived1 extends BaseClass {
@Test
public void testOne() {....}
}

What methods will be executed when Derived1 is executed through xml?

While executing 20 testcases using TestNg.xml(CMD)15 testcases have passed and 5 testcases have failed so how can you rerun the testcases which have failed without having to run the entire your testcases again?

Consider a scenario where you have two @Test annotations in your class for each of the below methods :
a) Login
b) CheckMail

Now due to the some reasons (Invalid credentials), @Test Login method fails. Now how can we skip executing the @Test CheckMail method when login fails (Since CheckMail method can be executed only after Login method is success).
