We have several CentOS 6.x systems that are incorporated into suites of special test equipment. One of the requirements for these systems is that they be kept up to date and they are kept up to date using yum once per week or more frequently, as needed. All of our CentOS 6.x systems have at least 2TB system disks and were installed with essentially everything that was available on the DVD at the time of initial setup.
One of our programs is currently in Beta Test which includes both command line and GUI operator inputs and responses. The functional testing requires operator inputs or responses within certain time frames. This timing has usually been implemented with a stopwatch that is operated by a test director. Other timing options would beneficial for complex testing scenarios
One of our test directors suggested that we use a digital count- down timer with audio outputs to prompt test operators for their inputs or responses at appropriate times. We have not found such a utility on our CentOS 6 distribution. If there is one available, we would appreciate any information that can be provided. Thanks.
