Tests are usually written in expect using Tcl, but you can also use a Tcl script to run a test denagnu that is not based on expect.

An assertion is a description of behavior. For example, interactive programs do not lend themselves very well to automated testing. The actual names of the directories containing tests must be prefixed by the dekagnu of the tool, and by convention end with the suffix.

DejaGnu has a number of global variables which are set to correspond to runtest command line arguments. Expect defines and uses a number of TCL global variables.

The results are triggered by calling the appropriate result procedure, which takes a string to identify the test concerned. If as is usual the command takes more than one line, the arguments must be surrounded by braces. We encourage you to make any test suites you create freely available, under the same terms as DejaGnu itself.
