  21 # Test essential Machine interface (MI) operations
  22 #
  23 # Verify that, using the MI, we can run a simple program and perform basic
  24 # debugging activities like: insert breakpoints, run the program,
  25 # step, next, continue until it ends and, last but not least, quit.
  26 #
  27 # The goal is not to test gdb functionality, which is done by other tests,
  28 # but to verify the correct output response to MI operations.
