Its purpose is to provide a single front end for all tests. DejaGnu provides a layer of abstraction which allows you to write tests that are portable to any host or target where a program must be tested.
All tests have the same output format.
This makes it easy to integrate testing into other software development processes. Tests are usually written in expect using Tcl, but you can also use a Tcl script to run a test suite that is not based on expect . When you have a cross configuration, the tests run on a different computer, controlled by the host running runtest . See section Defaults for runtest options . By default, runtest prints only the names of the tests it runs, output from any tests that have unexpected results, and a summary showing how many tests passed and how many failed.
