how to fail the test case in selenium 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: how do you test failed test in framework

- 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 3: why testing failed test cases

-> Why we would want to rerun the failed test cases?
	- If a bunch of tests are failing from a
    big regression suite, we don't want to
    rerun the whole suite again.
	-> Therefore we just re-run the failed tests to
    make sure those tests are actually failing and
    it is not a syncronization issue
