Re: [libvirt] [test-API PATCH 3/3] repo: Add test for console input and output operations
On 04/03/2012 09:20 PM, Peter Krempa wrote:
This test checks if the console input and output work as desired.
The
test takes as an argument a string, that is sent to the console and
another string that is expected to be read from the console. When those
two compare successfuly the test succeeds.

It'd better to raise 'TestError' exception from framework
because of
unexpected environment error, or something common for all of
tests.

we need a console_io_clean(params) function for use by clean flag
in testcase config
BTW, I tried the testcase, but don't know how to offer the
options to let it run successful
It always hang up, could you give a detailed comments.
