21 # Test essential Machine interface (MI) operations
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.
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.
