| >This document describes the functionality of DejaGnu, the |
| testing framework of the GNU project. DejaGnu is written in |
| <SPAN |
| CLASS="PRODUCTNAME" |
| >Expect</SPAN |
| >, which uses |
| <SPAN |
| CLASS="PRODUCTNAME" |
| >Tcl</SPAN |
| > as a command |
| language. <SPAN |
| CLASS="PRODUCTNAME" |
| >Expect</SPAN |
| > acts as a very |
| programmable shell. As with other Unix command shells, you can |
| run any program, but once the program is started, your test script |
| has programmable control over its input and output. This does not |
| just apply to the programs under test; <B |
| CLASS="COMMAND" |
| >expect</B |
| > |
| can also run any auxiliary program, such as |
| <B |
| CLASS="COMMAND" |
| >diff</B |
| > or <B |
| CLASS="COMMAND" |
| >sh</B |
| >, with full |
| control over its input and output.</P |
| ><P |
| >DejaGnu itself is merely a framework for the creation of |
| testsuites. Testsuites are distributed with each |
| application.</P |
