# Test essential Machine interface (MI) operations

#

# Verify that, using the MI, we can run a simple program and perform basic

# debugging activities like: insert breakpoints, run the program,

# step, next, continue until it ends and, last but not least, quit.

#

# The goal is not to test gdb functionality, which is done by other tests,

# but to verify the correct output response to MI operations.
