rerun failed test in testng code example

Example 1: how to run failed test

- I use a cucumber plugin that is called "rerun",
which allows me to run ONLY failed test cases.

-     How did I achieve that is:
	- I created a second runner class and
      name it FailedTestRunner which dedicated
      to running only failed scenarios.
	- Let's say I have 100 tests running in the 
      first run and ten of those tests are failed.
	- If we implemented "rerun" structure correctly,
      all of the failed tests are going to be
      stored in "rerun.txt"
	- Our "FailedTestRunner" class will be pointing
     to "rerun.txt", and when we run it,
     it will only run those failed tests.

Example 2: rerun failed test in testng

1. After the first run of an automated test run.
Right click on Project and click on Refresh

2. A folder will be generated named
“test-output” folder. Inside “test-output”
folder, you could find “testng-failed.xml”

3. Run “testng-failed.xml” to execute 
the failed test cases again. Right-click
on this file and click on run as and 
select the option called "testNG suite".
