DejaGnu is entirely written in <SPAN CLASS="PRODUCTNAME" >Expect</SPAN >, which uses <SPAN CLASS="PRODUCTNAME" >Tcl</SPAN > as a command language. <SPAN CLASS="PRODUCTNAME" >Expect</SPAN > serves as a very programmable shell; you can run any program, as with the usual Unix command shells---but once the program is started, your test script has fully programmable control of 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 creation of a test suites. Test suites are distributed separately for each GNU tool.</P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="book1.html" ><<< Previous</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="book1.html" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="overview.html" >Next >>></A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >DejaGnu</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" > </TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Overview</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
