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