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