RunAndVerify()

def googletest-break-on-failure-unittest.GTestBreakOnFailureUnitTest.RunAndVerify	(		self,
			env_var_value,
			flag_value,
			expect_seg_fault
	)

Runs googletest-break-on-failure-unittest_ and verifies that it does
(or does not) have a seg-fault.

Args:
  env_var_value:    value of the GTEST_BREAK_ON_FAILURE environment
                    variable; None if the variable should be unset.
  flag_value:       value of the --gtest_break_on_failure flag;
                    None if the flag should not be present.
  expect_seg_fault: 1 if the program is expected to generate a seg-fault;
                    0 otherwise.
