  18 # Test essential Machine interface (MI) operations
  19 #
  20 # Verify that, using the MI, we can run a simple program and perform basic
  21 # debugging activities like: insert breakpoints, run the program,
  22 # step, next, continue until it ends and, last but not least, quit.
  23 #
  24 # The goal is not to test gdb functionality, which is done by other tests,
  25 # but to verify the correct output response to MI operations.
