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