When you associate a Functional Tester project with a Rational project, you can use TestManager both to run your Functional Tester scripts and to coordinate testing activities from a single Windows computer, called the Local computer.
When a test runs, scripts play back on the Local computer or on the computers that you have designated as Agent computers. You use Agent computers to perform these tasks:
Run scripts on more than one computer. If you are running a test, you can save time by running the scripts on the next available Agent computer instead of running all scripts on the Local computer.
Test different machine configurations. If you are testing various hardware and software configurations, you can run scripts on Agent computers that are set up with different configurations.
Run Functional Tester scripts remotely on Linux or Windows computers. If you run Functional Tester scripts remotely, you must enable environments and configure applications on the Linux or Windows Agent computers. For information, see the Rational Functional Tester Installation Guide.
这个我也没具体试过,以后有时间会试的用一下,到时再具体回答些问题。
