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